Inhalt


Konzept

Wir entwickeln weiterhin Muster, die auf Zeitreihendaten basieren. Im ersten Artikel der Musterserie haben wir ein Toolkit für die Suche und Anzeige verschiedener Muster erstellt und eine Funktionalität für die Suche nach dem Muster „Pin-Bar“ aus den Price Action-Formationen entwickelt. In diesem Artikel werden wir die Funktionalität für die Suche nach verschiedenen Mustern in Preischarts weiterentwickeln und verfeinern und die Suche nach den Mustern „Inside-Bar“ der Price Action erstellen.

Wenn das „Pin-Bar“-Muster eine Formation aus einem Balken ist und nach den Proportionen eines Balkens gesucht wird, dann ist die „Inside-Bar“ eine Formation aus zwei Balken, die aus zwei Balken besteht - dem Mutter-Balken (dem Balken links) und dem definierenden Balken (Balken rechts):


Bei der Suche nach solchen Formationen reicht es nicht aus, nur die Proportionen eines Balkens zu vergleichen. Hier müssen wir zwei benachbarte Balken vergleichen. Außerdem können solche Formationen in einer Reihe laufen, und dann wird der Mutterbalken für alle ineinander verschachtelten Formationen einer sein, und zwar der ganz linke, während es viele definierende Balken geben wird - jeder rechte Balken jeder verschachtelten Formation. Der Balken ganz rechts ist der letzte der bestimmenden Balken der gesamten verschachtelten Formation. Um nach solchen Strukturen zu suchen, werden wir eine universelle Funktionalität implementieren und eine weitere Eigenschaft zu den Mustereigenschaften hinzufügen - die Öffnungszeit des Mutterbalkens. Anhand der Differenz zwischen den Eröffnungszeiten der Mutter- und der Definitionsbalken lässt sich die Anzahl der Balken bestimmen, die in der gesamten verschachtelten Formation enthalten sind. Dies ist nützlich, um Beschreibung des Musters auf dem Chart zu zeichnen. Mit anderen Worten, zusätzlich zu der Tatsache, dass jedes Muster mit einem einfachen Punkt auf dem Chart markiert werden kann, werden wir es ermöglichen, das Muster visuell anzuzeigen, indem wir einen Rahmen um die in der Formation enthaltenen Balken zeichnen. Dementsprechend werden wir die Möglichkeit schaffen, zwischen verschiedenen Methoden zur Darstellung von Mustern im Chart zu wählen.

Außerdem werden uns die heute geschaffenen Funktionen bei der Erstellung anderer Mustertypen helfen.


Verbesserung der Bibliotheksklassen

Bevor wir mit der Implementierung von Codes für das nächste Muster beginnen, sollten wir die vorgefertigten Dateien und Bibliotheksklassen fertigstellen.

Wir fügen in \MQL5\Include\DoEasy\Defines.mqh den Objekttyp „Bitmap“ zur Liste der Bibliotheksobjekttypen hinzu:

//+------------------------------------------------------------------+
//| List of library object types                                     |
//+------------------------------------------------------------------+
enum ENUM_OBJECT_DE_TYPE
  {
//--- Graphics
   OBJECT_DE_TYPE_GBASE =  COLLECTION_ID_LIST_END+1,              // "Base object of all library graphical objects" object type
   OBJECT_DE_TYPE_GELEMENT,                                       // "Graphical element" object type
   OBJECT_DE_TYPE_GFORM,                                          // Form object type
   OBJECT_DE_TYPE_GFORM_CONTROL,                                  // "Form for managing pivot points of graphical object" object type
   OBJECT_DE_TYPE_GSHADOW,                                        // Shadow object type
   OBJECT_DE_TYPE_GGLARE,                                         // Glare object type
   OBJECT_DE_TYPE_GBITMAP,                                        // Bitmap object type
   //--- WinForms
   OBJECT_DE_TYPE_GWF_BASE,                                       // WinForms Base object type (base abstract WinForms object)
   OBJECT_DE_TYPE_GWF_CONTAINER,                                  // WinForms container object type
   OBJECT_DE_TYPE_GWF_COMMON,                                     // WinForms standard control object type
   OBJECT_DE_TYPE_GWF_HELPER,                                     // WinForms auxiliary control object type
//--- Animation
//--- ...
//---...
 

Objekte vom Typ OBJ_BITMAP ermöglichen es, eine bmp-Ressource anzuhängen und verschiedene Primitive darauf zu zeichnen. Ein solches Objekt ist an die Balkenzeit und den Preis gebunden. Wir werden sie verwenden, um die Balken des Musters mit einem Rahmen zu umreißen.

Zusätzlich zu der Tatsache, dass Musterobjekte die Zeiten der Balken speichern, auf denen sie gebildet werden, werden wir auch die Arten von Mustern, die darauf gefunden wurden, dem Bibliotheksbalkenobjekt hinzufügen. Da es sich bei den Mustertypen um Bitflags handelt, können viele verschiedene Arten von Mustern in einer Variablen gespeichert werden. Aus dem Wert dieser Variablen können wir dann immer den Typ und dementsprechend den Namen aller auf dem Balken gefundenen Muster extrahieren.

Das ist praktisch, wenn man nach einem Muster sucht, mit dem man von einem Nutzerprogramm aus arbeiten will: Man holt sich ein Balkenobjekt, prüft die Arten von Mustern, die darauf gefunden werden, und arbeitet mit denen, deren Flags in die Variable geschrieben werden.

Wir fügen eine weitere Eigenschaft zu den Ganzzahl-Eigenschaften des Balkenobjekts hinzu und erhöhen die Anzahl der Ganzzahl-Eigenschaften des Balkenobjekts von 13 auf 14:

//+------------------------------------------------------------------+
//| Bar integer properties                                           |
//+------------------------------------------------------------------+
enum ENUM_BAR_PROP_INTEGER
  {
   BAR_PROP_TIME = 0,                                       // Bar period start time
   BAR_PROP_TYPE,                                           // Bar type (from the ENUM_BAR_BODY_TYPE enumeration)
   BAR_PROP_PERIOD,                                         // Bar period (timeframe)
   BAR_PROP_SPREAD,                                         // Bar spread
   BAR_PROP_VOLUME_TICK,                                    // Bar tick volume
   BAR_PROP_VOLUME_REAL,                                    // Bar exchange volume
   BAR_PROP_TIME_DAY_OF_YEAR,                               // Bar day serial number in a year
   BAR_PROP_TIME_YEAR,                                      // A year the bar belongs to
   BAR_PROP_TIME_MONTH,                                     // A month the bar belongs to
   BAR_PROP_TIME_DAY_OF_WEEK,                               // Bar week day
   BAR_PROP_TIME_DAY,                                       // Bar day of month (number)
   BAR_PROP_TIME_HOUR,                                      // Bar hour
   BAR_PROP_TIME_MINUTE,                                    // Bar minute
   BAR_PROP_PATTERNS_TYPE,                                  // Pattern types on the bar (pattern flags from the ENUM_PATTERN_TYPE enumeration)
  }; 
#define BAR_PROP_INTEGER_TOTAL (14)                         // Total number of integer bar properties

Wenn wir mit Listen von Zeitreihen nach Mustern suchen und ein Muster in einem Balken finden, fügen wir den Typ des gefundenen Musters zu eben dieser Variablen im Balkenobjekt hinzu. Basierend auf den Ergebnissen der Suche nach verschiedenen Arten von Mustern können in dieser Variablen in einem Balken die Flags der verschiedenen gefundenen Mustertypen aufgezeichnet werden.

Füge wir das Sortieren nach Mustertyp der Balken zur Liste der möglichen Sortierkriterien für Balkenobjekte:

//+------------------------------------------------------------------+
//| Possible bar sorting criteria                                    |
//+------------------------------------------------------------------+

Zuvor war für das Harami-Muster in der Liste der Mustertypen der Wert 0 angegeben. Das ist nicht ganz richtig. Es ist besser, wenn Null das Fehlen von Mustern auf dem Balken anzeigt.
Wir sollten dies beheben und eine Makrosubstitution hinzufügen, die die Gesamtzahl der in der Bibliothek verfügbaren Suchmuster angibt:

Hierbei handelt es sich um eine neue Art von grafischen Objekten für die Bibliothek, die an Preis/Zeit-Koordinaten gebunden sind und auf denen Sie auf dieselbe Weise zeichnen können wie auf den GUI-Elementen der Bibliothek. Aus diesem Grund wurde sie in diese Liste aufgenommen. Wahrscheinlich werden wir sie neben der Darstellung von Musterbalken im Preischart auch für andere Zwecke der Bibliothek verwenden.


Fügen wir in der Bibliotheksdatei \MQL5\Include\DoEasy\Data.mqh die Indizes für neue Bibliotheksmeldungen hinzu:

Oft ist es notwendig, die Gültigkeit der an Funktionen und Methoden übergebenen Symbol- und Periodenwerte zu überprüfen. Um Codewiederholungen zu vermeiden, implementieren wir die Funktionen, die den korrekten Symbolnamen und die Chartperiode zurückgeben, in \MQL5\Include\DoEasy\Services\DELib.mqh:

//+------------------------------------------------------------------+
//| Service functions                                                |
//+------------------------------------------------------------------+
//+------------------------------------------------------------------+
//| Correct and return a symbol name                                 |
//+------------------------------------------------------------------+
string CorrectSymbol(const string symbol) 
  {
   return(symbol==NULL || symbol=="" ? ::Symbol() : symbol);
  }
//+------------------------------------------------------------------+
//| Correct and return a timeframe name                              |
//+------------------------------------------------------------------+
ENUM_TIMEFRAMES CorrectTimeframe(const ENUM_TIMEFRAMES timeframe)
  {
   return(timeframe==PERIOD_CURRENT ? ::Period() : timeframe);
  }

Wenn NULL, ein leerer String, 0 oder PERIOD_CURRENT als Chart-Periode übergeben werden, geben die Funktionen das aktuelle Symbol oder den aktuellen Zeitrahmen zurück. In allen anderen Fällen geben sie die an die Funktion übergebenen Werte zurück. So werden wir nach und nach alle Codes in der Bibliothek, in denen ähnliche Prüfungen auf die Gültigkeit der an die Methoden übergebenen Werte durchgeführt werden, durch diese Funktionen ersetzen.

Wir werden hier auch die Funktionen hinzufügen, die Musterbeschreibungen zurückgeben:

     }
  }

Je nach dem an die Funktion übergebenen Mustertyp wird die entsprechende Textbeschreibung zurückgegeben.


Die Funktion, die die Anzahl und die Liste der Muster in einer ulong-Variablen zurückgibt:

//+------------------------------------------------------------------+
//| Return the number and list of patterns in the ulong variable     |
//+------------------------------------------------------------------+
int ListPatternsInVar(const ulong var,ulong &array[])
  {
   int size=0;
   ulong x=1;
//--- In the loop from 1 to the number of patterns PATTERNS_TOTAL-1
   for(int i=1;i<PATTERNS_TOTAL;i++)
     {
      //--- set the value of the pattern flag to be checked from the ENUM_PATTERN_TYPE enumeration by the loop index
      x=(i>1 ? x*2 : 1);
      ENUM_PATTERN_TYPE type=(ENUM_PATTERN_TYPE)x;
      //--- If the value passed to the function contains the pattern flag with x value,
      bool res=(var & type)==type;
      if(res)
        {
         //--- increase the size of the pattern array
         size++;
         ArrayResize(array,size,PATTERNS_TOTAL-1);
         //--- write the pattern type to the array
         array[size-1]=type;
        }
     }
//--- Return the number of pattern types stored in the variable
   return size;
  }

Die Funktion erhält die Variable, die die Musterflags enthält, und ein Array, in das die aus dieser Variable extrahierten Mustertypen geschrieben werden. Da jedes Flag doppelt so groß ist wie das vorherige, ist es einfach, den Wert des Flags in einer Schleife aus dem Wert des Schleifenindexes zu bilden und dann nach dem Vorhandensein eines solchen Flags im Variablenwert zu suchen. Wenn ein solches Flag in eine Variable geschrieben wird, wird der Mustertyp in ein Array geschrieben, das zuvor um 1 erhöht wurde, um einen neuen Mustertyp hineinzuschreiben. Am Ende der Schleife nach Mustertypen werden alle Muster, die in Form von Flags in die Variable geschrieben werden, in das Array eingetragen, das dann im Programm verwendet werden kann.


Die Funktion, die eine Beschreibung der Mustertypen in einer ulong-Variablen an das Journal sendet:

//+------------------------------------------------------------------------+
//| Send a description of pattern types in a ulong variable to the journal |
//+------------------------------------------------------------------------+
void PatternsInVarDescriptionPrint(const ulong var,const bool dash=false)
  {
   ulong array[];
//--- Get the number of patterns in the value passed to the function
   int total=ListPatternsInVar(var,array);
//--- In the loop by the array of patterns, obtain a description of the next pattern and print it
   for(int i=0;i<total;i++)
      Print((dash ? " - " : ""),PatternTypeDescription((ENUM_PATTERN_TYPE)array[i]));
  }

Die Methodenlogik wird in den Codekommentaren beschrieben.


Die Funktion, die eine Beschreibung der Mustertypen in einer ulong-Variablen zurückgibt:

//+------------------------------------------------------------------+
//| Return a description of pattern types in a ulong variable        |
//+------------------------------------------------------------------+
string PatternsInVarDescription(const ulong var,const bool dash=false)
  {
   ulong array[];
//--- Get the number of patterns in the value passed to the function
   int total=ListPatternsInVar(var,array);
   string txt="";
//--- In the loop by the array of patterns, obtain a description of the next pattern and add it to the text variable
   for(int i=0;i<total;i++)
      txt+=((dash ? " - " : "")+PatternTypeDescription((ENUM_PATTERN_TYPE)array[i]))+(i<total-1 ? "\n" : "");
//--- Return the obtained text
   return txt;
  }

Alle diese Funktionen sind von jeder Stelle des Programms aus zugänglich und ermöglichen dem Nutzer einen einfachen Zugriff auf die Listen der auf einem Balken erkannten Muster. Die Eigenschaft der Balken hat jetzt eine Variable, die die Flags der gefundenen Muster speichert. Anhand des Wertes dieser Eigenschaft und unter Verwendung der Funktionen können wir immer alle Arten von Mustern auf dem Balken extrahieren und im Programm verarbeiten. Genau das werden wir im Test-EA tun.


Die Objektklasse für grafische Elemente in der Datei \MQL5\Include\DoEasy\Objects\Graph\GCnvElement.mqh dient als Grundlage für die Erstellung komplexerer GUI-Elemente, aber es gibt einige Variablen in dieser Klasse, auf die von abgeleiteten Klassen nicht zugegriffen werden kann. Verschieben wir diese Variablen und Methoden aus dem privaten Bereich in den geschützten Bereich:

//+------------------------------------------------------------------+
//| Class of the graphical element object                            |
//+------------------------------------------------------------------+
class CGCnvElement : public CGBaseObj
  {
protected:
   CGCnvElement     *m_element_main;                           // Pointer to the initial parent element within all the groups of bound objects
   CGCnvElement     *m_element_base;                           // Pointer to the parent element within related objects of the current group
   CCanvas           m_canvas;                                 // CCanvas class object
   CPause            m_pause;                                  // Pause class object
   bool              m_shadow;                                 // Shadow presence
   color             m_chart_color_bg;                         // Chart background color
   uint              m_duplicate_res[];                        // Array for storing resource data copy
   color             m_array_colors_bg[];                      // Array of element background colors
   color             m_array_colors_bg_dwn[];                  // Array of control background colors when clicking on the control
   color             m_array_colors_bg_ovr[];                  // Array of control background colors when hovering the mouse over the control

   int               m_shift_coord_x;                          // Offset of the X coordinate relative to the base object
   int               m_shift_coord_y;                          // Offset of the Y coordinate relative to the base object

//--- Create (1) the object structure and (2) the object from the structure

...

   long              m_long_prop[CANV_ELEMENT_PROP_INTEGER_TOTAL];   // Integer properties
   double            m_double_prop[CANV_ELEMENT_PROP_DOUBLE_TOTAL];  // Real properties
   string            m_string_prop[CANV_ELEMENT_PROP_STRING_TOTAL];  // String properties

   ENUM_FRAME_ANCHOR m_text_anchor;                            // Current text alignment
   int               m_text_x;                                 // Text last X coordinate
   int               m_text_y;                                 // Text last Y coordinate

protected:   
//--- Initialize property values
   void              Initialize(const ENUM_GRAPH_ELEMENT_TYPE element_type,
                                const int element_id,const int element_num,
                                const int x,const int y,const int w,const int h,
                                const string descript,const bool movable,const bool activity);
                                
private:   
//--- Return the index of the array the order's (1) double and (2) string properties are located at


Wir schreiben im Abschnitt der Methoden für die Arbeit mit dem Text zwei Methoden für den Zugriff auf die Einstellung der privaten Klasseneigenschaften:

//+------------------------------------------------------------------+
//| Methods of working with text                                     |
//+------------------------------------------------------------------+
//--- Set the last text coordinate (1) X, (2) Y
   void              SetTextLastX(const int x)                    { this.m_text_x=x;                                                   }
   void              SetTextLastY(const int y)                    { this.m_text_y=y;                                                   }
//--- Return (1) alignment type (anchor method), the last (2) X and (3) Y text coordinate

Die Methoden sind im Konstruktor von abgeleiteten Klassen nützlich, da die Platzierung dieser Variablen in einem geschützten Bereich der Klasse noch größere Änderungen an anderen Klassen nach sich zieht. Für den Moment werden wir uns mit diesen Methoden begnügen, ohne die Variablen umzubenennen.

Bisher haben wir Objekte verwendet, die auf dem Objekt OBJ_BITMAP_LABEL - „Graphical label“ basieren:


Die Position des Ankerpunkts relativ zum Etikett kann aus der Aufzählung ENUM_ANCHOR_POINT ausgewählt werden. Die Koordinaten der Ankerpunkte werden in Pixel angegeben.

Sie können auch die Verankerungsecke der Bitmap aus der Aufzählung ENUM_BASE_CORNER auswählen.

Diese Objekte haben Bildschirmkoordinaten in Pixeln und eignen sich für die Erstellung grafischer Steuerelemente.

Wenn wir aber ein solches Objekt an Preis/Zeit-Koordinaten binden und gleichzeitig genau die gleichen Möglichkeiten zum Zeichnen innerhalb des Objekts wie auf der Leinwand nutzen wollen, dann kommt das grafische Objekt OBJ_BITMAP zur Hilfe:


Dies ist genau das gleiche grafische Objekt, das entweder eine Rasterbilddatei oder eine dynamisch erstellte Ressource als Bild verwenden kann, in dem das Rendering stattfindet.

Die Methoden der Klasse CCanvas ermöglichen die Erstellung eines Bitmap-Objekts. Daher müssen wir lediglich eine Zeichnungsobjektklasse erstellen, die auf der Klasse der grafischen Elemente basiert und nur geringfügige Änderungen aufweist.


Klasse der Bitmap-Grafikelemente

Wir erstellen im Bibliotheksverzeichnis \MQL5\Include\DoEasy\Objects\Graph\ eine neue Datei GCnvBitmap.mqh der Klasse CGCnvBitmap.
Die Klasse sollte von der grafischen Elementklasse abgeleitet sein, deren Datei in die Datei der erstellten Klasse aufgenommen werden sollte:

class CGCnvBitmap : public CGCnvElement
  {
  }


Im Körper der Klasse brauchen wir nur einige private Variablen und Methoden, um mit ihnen zu arbeiten, eine virtuelle Methode, um ein Objekt zu erzeugen, sowie Konstruktoren mit einem Destruktor. Alles andere ist bereits in der übergeordneten Klasse implementiert:

      this.Initialize(element_type,0,0,0,0,w,h,descript,false,false);
      this.SetVisibleFlag(false,false);
      this.SetTimePrice(time,price);
     }
   else
     {
      ::Print(DFUN,CMessage::Text(MSG_LIB_SYS_FAILED_CREATE_ELM_OBJ),"\"",this.TypeElementDescription(element_type),"\" ",this.NameObj());
     }
  }

Hier verwenden wir den Standardkonstruktor der übergeordneten Klasse, da in ihm alle Objektparameter gesetzt werden und das Objekt erstellt wird. Um die Parameter in diesem Konstruktor nicht neu zu definieren und um ein Objekt eines neuen Typs nicht zu löschen und neu zu erstellen, machen wir das alles gleich hier, in diesen Konstruktoren, unter Verwendung des Standardkonstruktors des übergeordneten Objekts.


Die virtuelle Methode zur Erstellung eines grafischen Bitmap-Objekts:

//+------------------------------------------------------------------+
//| Create the graphical bitmap object                               |
//+------------------------------------------------------------------+
bool CGCnvBitmap::Create(const long chart_id,     // Chart ID
                         const int wnd_num,       // Chart subwindow
                         const int x,             // X coordinate
                         const int y,             // Y coordinate
                         const int w,             // Width
                         const int h,             // Height
                         const bool redraw=false) // Flag indicating the need to redraw
                         
  {
   ::ResetLastError();
   if(this.m_canvas.CreateBitmap((chart_id==NULL ? ::ChartID() : chart_id),wnd_num,this.m_name,x,y,w,h,COLOR_FORMAT_ARGB_NORMALIZE))
     {
      this.Erase(CLR_CANV_NULL);
      this.m_canvas.Update(redraw);
      this.m_shift_y=(int)::ChartGetInteger((chart_id==NULL ? ::ChartID() : chart_id),CHART_WINDOW_YDISTANCE,wnd_num);
      return true;
     }
   int err=::GetLastError();
   int code=(err==0 ? (w<1 ? MSG_CANV_ELEMENT_ERR_FAILED_SET_WIDTH : h<1 ? MSG_CANV_ELEMENT_ERR_FAILED_SET_HEIGHT : ERR_OBJECT_ERROR) : err);
   string subj=(w<1 ? "Width="+(string)w+". " : h<1 ? "Height="+(string)h+". " : "");
   CMessage::ToLog(DFUN_ERR_LINE+subj,code,true);
   return false;
  }

Im Gegensatz zur gleichen Methode der Elternklasse wird hier die Methode verwendet, um die Methode CreateBitmap() der Klasse CCanvas anstelle der Methode CreateBitmapLabel() zu erstellen. Dies ist der einzige Unterschied zwischen dieser Methode und der Methode der übergeordneten Klasse.


Die Methoden zum Festlegen von Preis- und Zeitkoordinaten für ein Bitmap-Objekt:

//+------------------------------------------------------------------+
//| Set the time coordinate                                          |
//+------------------------------------------------------------------+
bool CGCnvBitmap::SetTime(const datetime time)
  {
   string name=this.NameObj();
   if(name==NULL || name=="")
      return false;
   ::ResetLastError();
   if(!::ObjectSetInteger(this.ChartID(),name,OBJPROP_TIME,time))
     {
      ::PrintFormat("%s%s. %s %s",DFUN,CMessage::Text(MSG_ERR_FAILED_SET_BITMAP_OBJ_TIME),CMessage::Text(MSG_LIB_SYS_ERROR),::GetLastError());
      return false;
     }
   this.m_time=time;
   return true;
  }
//+------------------------------------------------------------------+
//| Set the price coordinate                                         |
//+------------------------------------------------------------------+
bool CGCnvBitmap::SetPrice(const double price)
  {
   string name=this.NameObj();
   if(name==NULL || name=="")
      return false;
   ::ResetLastError();
   if(!::ObjectSetDouble(this.ChartID(),name,OBJPROP_PRICE,price))
     {
      ::PrintFormat("%s%s. %s %s",DFUN,CMessage::Text(MSG_ERR_FAILED_SET_BITMAP_OBJ_PRICE),CMessage::Text(MSG_LIB_SYS_ERROR),::GetLastError());
      return false;
     }
   this.m_price=price;
   return true;
  }
//+------------------------------------------------------------------+
//| Set both coordinates                                             |
//+------------------------------------------------------------------+
bool CGCnvBitmap::SetTimePrice(const datetime time,const double price)
  {
   if(!this.SetTime(time))
      return false;
   return this.SetPrice(price);
  }
//+------------------------------------------------------------------+

Kurz gesagt: Wenn es nicht möglich war, eine Eigenschaft in einem grafischen Objekt zu setzen, zeigen wir eine entsprechende Meldung im Journal an und geben false zurück.
Wenn eine Eigenschaft erfolgreich auf ein Objekt gesetzt wird, wird ein neuer Wert in die Klassenvariable geschrieben und true zurückgegeben.


Wir deklarieren in der Verwaltungsklasse für grafische Elemente in der Datei \MQL5\Include\DoEasy\Objects\Graph\GraphElmControl.mqh die Methode zur Erstellung eines Bitmap-Objekts:

//+------------------------------------------------------------------+
//| Class for managing graphical elements                            |
//+------------------------------------------------------------------+
class CGraphElmControl : public CObject
  {
private:
   int               m_type;                          // Object type
   int               m_type_node;                     // Type of the object the graphics is constructed for
//--- Set general parameters for standard graphical objects
   void              SetCommonParamsStdGraphObj(const long chart_id,const string name);
public:
//--- Return itself
   CGraphElmControl *GetObject(void)                  { return &this;               }
//--- Set a type of the object the graphics is constructed for
   void              SetTypeNode(const int type_node) { this.m_type_node=type_node; }
   
//--- Create a form object
   CForm            *CreateForm(const int form_id,const long chart_id,const int wnd,const string name,const int x,const int y,const int w,const int h);
   CForm            *CreateForm(const int form_id,const int wnd,const string name,const int x,const int y,const int w,const int h);
   CForm            *CreateForm(const int form_id,const string name,const int x,const int y,const int w,const int h);

//--- Create Bitmap object
   CGCnvBitmap      *CreateBitmap(const int obj_id,const long chart_id,const int wnd,const string name,const datetime time,const double price,const int w,const int h,const color clr);
   
//--- Creates the trend line standard graphical object


Nun schreiben wir die Implementierung außerhalb des Hauptteils der Klasse:

//+------------------------------------------------------------------+
//| Create Bitmap object                                             |
//+------------------------------------------------------------------+
CGCnvBitmap *CGraphElmControl::CreateBitmap(const int obj_id,const long chart_id,const int wnd,const string name,const datetime time,const double price,const int w,const int h,const color clr)
  {
   CGCnvBitmap *obj=new CGCnvBitmap(GRAPH_ELEMENT_TYPE_BITMAP,NULL,NULL,obj_id,0,chart_id,wnd,name,time,price,w,h,clr,200);
   return obj;
  }

Die Methode erstellt ein neues Objekt der Klasse CDCnvBitmap mit den übergebenen Parametern und einer Deckkraft von 200 und gibt den Zeiger auf das erstellte Objekt zurück.


Wir schreiben nun in die Basisobjektklasse der CBaseObj-Bibliothek, d. h. in die Datei \MQL5\Include\DoEasy\Objects\BaseObj.mqh, die Methoden zur Erstellung eines Bitmap-Objekts:

//+------------------------------------------------------------------+
//| Methods for handling graphical elements                          |
//+------------------------------------------------------------------+
//--- Create a form object on a specified chart in a specified subwindow
   CForm            *CreateForm(const int form_id,const long chart_id,const int wnd,const string name,const int x,const int y,const int w,const int h)
                       { return this.m_graph_elm.CreateForm(form_id,chart_id,wnd,name,x,y,w,h);                }
//--- Create a form object on the current chart in a specified subwindow
   CForm            *CreateForm(const int form_id,const int wnd,const string name,const int x,const int y,const int w,const int h)
                       { return this.m_graph_elm.CreateForm(form_id,wnd,name,x,y,w,h);                         }
//--- Create the form object on the current chart in the main window
   CForm            *CreateForm(const int form_id,const string name,const int x,const int y,const int w,const int h)
                       { return this.m_graph_elm.CreateForm(form_id,name,x,y,w,h);                             }
   
//--- Create a bitmap object on a specified chart in a specified subwindow
   CGCnvBitmap      *CreateBitmap(const int obj_id,const long chart_id,const int wnd,const string name,const datetime time,const double price,const int w,const int h,const color clr)
                       { return this.m_graph_elm.CreateBitmap(obj_id,chart_id,wnd,name,time,price,w,h,clr);   }
//--- Create a bitmap object on the current chart in a specified subwindow
   CGCnvBitmap      *CreateBitmap(const int obj_id,const int wnd,const string name,const datetime time,const double price,const int w,const int h,const color clr)
                       { return this.m_graph_elm.CreateBitmap(obj_id,::ChartID(),wnd,name,time,price,w,h,clr);}
//--- Create the bitmap object on the current chart in the main window
   CGCnvBitmap      *CreateBitmap(const int obj_id,const string name,const datetime time,const double price,const int w,const int h,const color clr)
                       { return this.m_graph_elm.CreateBitmap(obj_id,::ChartID(),0,name,time,price,w,h,clr);  }
   
//--- Create a standard graphical trend line object in the specified subwindow of the specified chart

Drei Methoden zum Erstellen eines Zeichnungsobjekts (1) auf dem angegebenen Chart im angegebenen Unterfenster, (2) auf dem aktuellen Chart im angegebenen Unterfenster und (3) auf dem aktuellen Chart im Hauptfenster. Die Methoden geben einfach das Ergebnis des Aufrufs der Methode zur Erstellung eines Bitmap-Objekts der Klasse CGraphElmControl mit den oben angegebenen Parametern zurück.

Jetzt können wir ein Zeichenobjekt aus einem beliebigen Bibliotheksobjekt erstellen, um etwas visuell zu gestalten. Übrigens konnten wir früher schon einige grafische Primitive und GUI-Elemente aus beliebigen Bibliotheksobjekten erstellen. Jetzt wurde der Liste ein Bitmap-Objekt hinzugefügt.

Die Klasse des grafischen Formularobjekts wird von der Klasse des grafischen Elements geerbt. Dementsprechend ist die grafische Elementdatei mit der Formularobjektklassendatei verbunden. Da wir nun eine weitere Klasse haben, die von dem grafischen Element geerbt wurde - die Bitmap-Objektklasse -, werden wir, um alle diese Klassen optimal miteinander zu verbinden, die Bitmap-Objektklassendatei mit der Formularobjektklassendatei verbinden. Da diese Klasse von dem grafischen Element abgeleitet ist, sind beide Klassen in der Formularobjektklasse verfügbar.

Die Formularobjektklassendatei \MQL5\Include\DoEasy\Objects\Graph\Form.mqh erhält die Bitmap-Objektklassendatei anstelle der grafischen Elementdatei:

class CForm : public CGCnvElement
  {

Jetzt sind sowohl das Elementobjekt als auch das Bitmap-Objekt im Formularobjekt verfügbar. Dementsprechend werden in anderen Dateien, in denen das Element-Objekt benötigt wird, beide Objekte verfügbar sein.


Tragen wir die gefundenen Objekte in das Balkenobjekt ein.
Dazu schreiben wir in den öffentlichen Abschnitt der Datei der Balken-Objektklasse \MQL5\Include\DoEasy\Objects\Series\Bar.mqh die Methode, die einen neuen Mustertyp zur Balken-Eigenschaft hinzufügt:

//--- Return itself
   CBar             *GetObject(void)                                    { return &this;}
//--- Set (1) bar symbol, timeframe and time, (2) bar object parameters
   void              SetSymbolPeriod(const string symbol,const ENUM_TIMEFRAMES timeframe,const datetime time);
   void              SetProperties(const MqlRates &rates);
//--- Add the pattern type on bar
   void              AddPattern(const ENUM_PATTERN_TYPE pattern_type)   { this.m_long_prop[BAR_PROP_PATTERNS_TYPE] |=pattern_type;           }

//--- Compare CBar objects by all possible properties (for sorting the lists by a specified bar object property)
   virtual int       Compare(const CObject *node,const int mode=0) const;
//--- Compare CBar objects by all properties (to search for equal bar objects)
   bool              IsEqual(CBar* compared_bar) const;
//--- Constructors
                     CBar(){ this.m_type=OBJECT_DE_TYPE_SERIES_BAR; }
                     CBar(const string symbol,const ENUM_TIMEFRAMES timeframe,const datetime time,const string source);
                     CBar(const string symbol,const ENUM_TIMEFRAMES timeframe,const MqlRates &rates);

Die Methode empfängt den Mustertyp, und sein Wert (Bitmaske) wird zum Wert der Eigenschaft BAR_PROP_PATTERNS_TYPE hinzugefügt. Mit dem logischen Operator „oder“ können wir einer Variablen verschiedene Typen hinzufügen, ohne den Variablenwert zu überschreiben. So können mehrere verschiedene Arten von Mustern in einer Variablen gespeichert werden.


Im Abschnitt Beschreibungen der Balken-Eigenschaften, deklarieren wir die Methode, die eine Liste von Mustern im übergebenen Array zurückgibt und die Methode, die eine Liste von Mustern auf einem Balken an das Journal ausgibt:

//+------------------------------------------------------------------+
//| Descriptions of bar object properties                            |
//+------------------------------------------------------------------+
//--- Get description of a bar's (1) integer, (2) real and (3) string properties
   string            GetPropertyDescription(ENUM_BAR_PROP_INTEGER property);
   string            GetPropertyDescription(ENUM_BAR_PROP_DOUBLE property);
   string            GetPropertyDescription(ENUM_BAR_PROP_STRING property);

//--- Return the bar type description
   string            BodyTypeDescription(void)  const;
//--- Display the description of the object properties in the journal (full_prop=true - all properties, false - supported ones only - implemented in descendant classes)
   virtual void      Print(const bool full_prop=false,const bool dash=false);
//--- Display a short description of the object in the journal
   virtual void      PrintShort(const bool dash=false,const bool symbol=false);
//--- Return the (1) short name, (2) description of bar object parameters and (3) a list of patterns in the passed array
   virtual string    Header(void);
   string            ParameterDescription(void);
   int               GetPatternsList(ulong &array[]);
//--- Display a list of patterns on the bar in the journal
   void              PatternTypeDescriptionPrint(const bool dash=false);
//---
  };


Wir setzen in der Methode, die die Parameter des Balkenobjekts festlegt, den Mustertyp des Balkens als nicht vorhanden fest (der Variablenwert ist Null):

//+------------------------------------------------------------------+
//| Set bar object parameters                                        |
//+------------------------------------------------------------------+
void CBar::SetProperties(const MqlRates &rates)
  {
   this.SetProperty(BAR_PROP_SPREAD,rates.spread);
   this.SetProperty(BAR_PROP_VOLUME_TICK,rates.tick_volume);
   this.SetProperty(BAR_PROP_VOLUME_REAL,rates.real_volume);
   this.SetProperty(BAR_PROP_TIME,rates.time);
   this.SetProperty(BAR_PROP_TIME_YEAR,this.TimeYear());
   this.SetProperty(BAR_PROP_TIME_MONTH,this.TimeMonth());
   this.SetProperty(BAR_PROP_TIME_DAY_OF_YEAR,this.TimeDayOfYear());
   this.SetProperty(BAR_PROP_TIME_DAY_OF_WEEK,this.TimeDayOfWeek());
   this.SetProperty(BAR_PROP_TIME_DAY,this.TimeDay());
   this.SetProperty(BAR_PROP_TIME_HOUR,this.TimeHour());
   this.SetProperty(BAR_PROP_TIME_MINUTE,this.TimeMinute());
//---
   this.SetProperty(BAR_PROP_OPEN,rates.open);
   this.SetProperty(BAR_PROP_HIGH,rates.high);
   this.SetProperty(BAR_PROP_LOW,rates.low);
   this.SetProperty(BAR_PROP_CLOSE,rates.close);
   this.SetProperty(BAR_PROP_CANDLE_SIZE,this.CandleSize());
   this.SetProperty(BAR_PROP_CANDLE_SIZE_BODY,this.BodySize());
   this.SetProperty(BAR_PROP_CANDLE_BODY_TOP,this.BodyHigh());
   this.SetProperty(BAR_PROP_CANDLE_BODY_BOTTOM,this.BodyLow());
   this.SetProperty(BAR_PROP_CANDLE_SIZE_SHADOW_UP,this.ShadowUpSize());
   this.SetProperty(BAR_PROP_CANDLE_SIZE_SHADOW_DOWN,this.ShadowDownSize());
//---
   this.SetProperty(BAR_PROP_RATIO_BODY_TO_CANDLE_SIZE,this.CandleRatioBodyToCandleSize());
   this.SetProperty(BAR_PROP_RATIO_UPPER_SHADOW_TO_CANDLE_SIZE,this.CandleRatioUpperShadowToCandleSize());
   this.SetProperty(BAR_PROP_RATIO_LOWER_SHADOW_TO_CANDLE_SIZE,this.CandleRatioLowerShadowToCandleSize());
   this.SetProperty(BAR_PROP_PATTERNS_TYPE,0);
   this.SetProperty(BAR_PROP_TYPE,this.BodyType());
//--- Set the object type to the object of the graphical object management class
   this.m_graph_elm.SetTypeNode(this.m_type);
  }


Außerhalb des Klassenkörpers schreiben wir die Methode, die eine Liste der Muster im übergebenen Array zurückgibt:

//+------------------------------------------------------------------+
//| Return the list of patterns in the passed array                  |
//+------------------------------------------------------------------+
int CBar::GetPatternsList(ulong &array[])
  {
   return ListPatternsInVar(this.GetProperty(BAR_PROP_PATTERNS_TYPE),array);
  }

Das Array wird an die Methode übergeben und das Ergebnis der Ausführung der oben implementierten Funktion ListPatternsInVar() wird zurückgegeben. In diesem Fall wird die Liste aller Muster auf dem Balken in das Array gestellt, das durch den Link an die Methode übergeben wird.


Die Methode zur Anzeige die Beschreibung der Muster eines Balkens im Journal:

//+------------------------------------------------------------------+
//| Display the description of patterns on the bar in the journal    |
//+------------------------------------------------------------------+
void CBar::PatternTypeDescriptionPrint(const bool dash=false)
  {
   ulong patt=this.GetProperty(BAR_PROP_PATTERNS_TYPE);
   ::Print(CMessage::Text(MSG_LIB_TEXT_BAR_PATTERNS_TYPE),": ",(patt>0 ? "" : CMessage::Text(MSG_LIB_PROP_EMPTY)));
   if(patt>0)
      ::Print(PatternsInVarDescription(patt,dash));
  }

Zuvor haben wir die Funktion PatternsInVarDescription() geschrieben, die eine Zeichenkette mit Beschreibungen aller Muster zurückgibt, deren Flags in der Variablen enthalten sind. Hier senden wir den Wert der Variablen, die die Balken-Eigenschaft BAR_PROP_PATTERNS_TYPE speichert, an diese Funktion und drucken die von der Funktion erhaltene Zeichenkette in das Journal.


Wir fügen in der Methode, die die Beschreibung der Eigenschaft Balken integer zurückgibt, die Rückgabe der Beschreibung des Eigenschaftswerts BAR_PROP_PATTERNS_TYPE hinzu:

//+------------------------------------------------------------------+
//| Return the description of the bar integer property               |
//+------------------------------------------------------------------+

Lassen Sie uns Verbesserungen an der Datei \MQL5\Include\DoEasy\Objects\Series\Patterns\Pattern.mqh vornehmen.

Da wir den Zeiger auf das Balkenobjekt, auf dem das Muster gefunden wurde, auf das Musterobjekt setzen werden, müssen wir die Klassendatei des Balkenobjekts in die Klassendatei des Musterobjekts aufnehmen. Das Muster hat eine Basis und einen „Mutterbalken“. Für den Basisbalken verwenden wir den Zeiger auf das Balkenobjekt (den Balken, auf dem das Muster gefunden wurde). Im Falle des „Mutter“-Balkens erstellen wir die MqlRates-Struktur, in der die Balkendaten gespeichert werden sollen. Auf diese Weise haben wir immer alle Daten über die Balken, die von dem Muster „abgedeckt“ werden. Wenn es sich übrigens um ein Muster aus einem Balken handelt, sind der Mutter- und der Basisbalken derselbe Balken. Wir werden das Muster mit Hilfe des Bitmap-Objekts „umreißen“, dessen Klasse hier erstellt wurde. Wir deklarieren den Zeiger auf das Klassenobjekt im geschützten Abschnitt der abstrakten Musterobjektklasse. Um die erforderliche Größe des Musters für die Balken des Musters berechnen zu können, müssen wir die Abmessungen und Parameter des Charts kennen. Wir deklarieren die Variablen zum Speichern der Chartparameter, die zur Berechnung der Größe des Bitmap-Objekts erforderlich sind.

Implementierung der Methode, die die Daten des „Mutter“-Balkens festlegt:

//+------------------------------------------------------------------+
//| Set the "mother" bar data                                        |
//+------------------------------------------------------------------+
void CPattern::SetMotherBarData(MqlRates &data)
  {
   this.m_mother_bar_prop.open=data.open;
   this.m_mother_bar_prop.high=data.high;
   this.m_mother_bar_prop.low=data.low;
   this.m_mother_bar_prop.close=data.close;
   this.m_mother_bar_prop.time=data.time;
   this.SetProperty(PATTERN_PROP_MOTHERBAR_TIME,data.time);
  }

Die Methode empfängt die Balkenstruktur, und die erforderlichen Strukturfelder werden auf die entsprechenden Strukturfelder der Struktur der Mitgliedsvariablen der Klasse m_mother_bar_prop gesetzt. Zusätzlich wird die Zeit aus der übergebenen Balkenstruktur in die Zeit-Eigenschaft des Mutterbalkens geschrieben - dieser Wert ist in den Objekteigenschaften vorhanden und sollte korrekt ausgefüllt werden.

Die Methode, die das Info-Panel auf dem Chart anzeigt , erhält die Eingabe, ohne dass das Chart neu gezeichnet werden muss. Das Chart wird neu gezeichnet, wenn der Variablenwert auf true gesetzt wird:

//+------------------------------------------------------------------+
//| Display the info panel on the chart                              |
//+------------------------------------------------------------------+
void CPattern::ShowInfoPanel(const int x,const int y,const bool redraw=true)
  {
//--- If there is no panel object yet, create it
   if(this.m_form==NULL)
      if(!this.CreateInfoPanel())
         return;
//--- Get the chart width and height
   int chart_w=(int)::ChartGetInteger(this.m_chart_id,CHART_WIDTH_IN_PIXELS);
   int chart_h=(int)::ChartGetInteger(this.m_chart_id,CHART_HEIGHT_IN_PIXELS);
//--- Calculate the X and Y coordinates of the panel so that it does not go beyond the chart
   int cx=(x+this.m_form.Width() >chart_w-1 ? chart_w-1-this.m_form.Width()  : x);
   int cy=(y+this.m_form.Height()>chart_h-1 ? chart_h-1-this.m_form.Height() : y);
//--- Set the calculated coordinates and display the panel
   if(this.m_form.SetCoordX(cx) && this.m_form.SetCoordY(cy))
      this.m_form.Show();
   if(redraw)
      ::ChartRedraw(this.m_chart_id);
  }

Dies wurde so gemacht, dass das Panel mit der Beschreibung des Musters ohne Verzögerung erscheint, nachdem der Mauszeiger über den Balken mit dem Muster bewegt wurde. Wenn es mehrere Muster auf diesem Balken gibt, sollte der Wert dieser Variable für alle Infotafeln, wenn sie auf dem Chart angezeigt werden, auf false gesetzt werden, außer für die letzte, die auf true gesetzt wird. In diesem Fall wird das Chart erst dann neu gezeichnet, wenn das letzte Feld (und nicht jedes einzelne) angezeigt wird.

Da Muster auf zwei Arten im Chart angezeigt werden können - als Punkte und als Bitmap-Objekte - sollten wir die Methode zur Anzeige des Mustersymbols im Chart fertigstellen:

//+------------------------------------------------------------------+
//| Display the pattern icon on the chart                            |
//+------------------------------------------------------------------+
void CPattern::Show(const bool redraw=false)
  {
   if(this.m_draw_dots)
     {
      ::ObjectSetInteger(this.m_chart_id,this.m_name_graph_obj,OBJPROP_TIMEFRAMES,OBJ_ALL_PERIODS);
      return;
     }
   if(this.m_bitmap!=NULL)
      this.m_bitmap.Show();
   if(redraw)
      ::ChartRedraw(this.m_chart_id);
  }

Wenn wir Punkte verwenden, schalten wir die Sichtbarkeit des grafischen Objekts wie zuvor ein. Wenn wir das Bitmap-Objekt verwenden, rufen wir dessen Methode Show() auf, falls vorhanden. Wir aktualisieren daher das Chart, wenn das Redraw-Flag gesetzt ist.

Auch verfeinern wir die Methode zum Ausblenden des Mustersymbols im Chart:

//+------------------------------------------------------------------+
//| Hide the pattern icon on the chart                               |
//+------------------------------------------------------------------+
void CPattern::Hide(const bool redraw=false)
  {
   if(this.m_draw_dots)
     {
      ::ObjectSetInteger(this.m_chart_id,this.m_name_graph_obj,OBJPROP_TIMEFRAMES,OBJ_NO_PERIODS);
      return;
     }
   if(this.m_bitmap!=NULL)
      this.m_bitmap.Hide();
   if(redraw)
      ::ChartRedraw(this.m_chart_id);
  }


Die Methode, mit der die Breite des Bitmap-Objekts berechnet wird:

//+------------------------------------------------------------------+
//| Calculate the bitmap object width                                |
//+------------------------------------------------------------------+
int CPattern::GetBitmapWidth(void)
  {
//--- Calculate the width of the chart candles in pixels
   int px=int(1<<this.m_chart_scale);
//--- Calculate the number of bars that make up the pattern
   int num_bars=::Bars(this.Symbol(),this.Timeframe(),this.MotherBarTime(),this.Time());
   if(num_bars==0)
      num_bars=(int)this.Candles();
//--- Calculate and return the width of the bitmap object
   return (px*num_bars*2)-px+1;
  }

Je nach Maßstab des Charts berechnen wir die Breite der Kerzen in Pixeln. Dann wird die Breite des Musters in Balken ermittelt, und aus diesen beiden Werten wird die erforderliche Breite des Musterobjekts berechnet und zurückgegeben.


Die Methode zur Berechnung der Höhe des Zeichnungsobjekts:

//+------------------------------------------------------------------+
//| Calculate the bitmap object height                               |
//+------------------------------------------------------------------+
int CPattern::GetBitmapHeight(void)
  {
//--- Calculate the chart price range and pattern price range
   double chart_price_range=this.m_chart_price_max-this.m_chart_price_min;
   double patt_price_range=this.MotherBarHigh()-this.MotherBarLow();
//--- Using the calculated price ranges, calculate and return the height of the bitmap object
   return (int)ceil(patt_price_range*this.m_chart_height_px/chart_price_range)+8;
  }

Hier erhalten wir die Kursspanne des Charts vom Höchst- bis zum Tiefstkurs auf dem Chart und die Kursspanne von Hoch und Tief des Mutterbalkens des Musters. Dann berechnen wir das Verhältnis eines Bereichs zu einem anderen in Pixeln und geben die resultierende Höhe des Bitmap-Objekts zurück, indem Sie 8 Pixel dazu addieren - vier oben und vier unten.

Im Konstruktor des Musters „Pin-Bar“ legen wir die Anzahl der verschachtelten Muster gleich dem Wert der Musterbalken (1) fest:

//+------------------------------------------------------------------+
//| Constructor                                                      |
//+------------------------------------------------------------------+
CPatternPinBar::CPatternPinBar(const uint id,const string symbol,const ENUM_TIMEFRAMES timeframe,MqlRates &rates,const ENUM_PATTERN_DIRECTION direct) : 
   CPattern(PATTERN_STATUS_PA,PATTERN_TYPE_PIN_BAR,id,direct,symbol,timeframe,rates)
  {
   this.SetProperty(PATTERN_PROP_NAME,"Pin Bar");
   this.SetProperty(PATTERN_PROP_CANDLES,1);
   this.m_bars_formation=(int)this.GetProperty(PATTERN_PROP_CANDLES);
  }


Erstellen wir nun die Klasse für das neue Preisaktionsmuster „Inside-Bar“.

Die Klasse des Musters „Inside-Bar“

De neue Musterklasse „Inside-Bar“ erstellen wir in derselben Datei, in der auch die Klassen des abstrakten Musters und des Musters „Pin-Bar“ gespeichert sind. Im Wesentlichen müssen wir nur einige virtuelle Methoden und Eigenschaftswerte des Musters schreiben (überschreiben). Die Klasse sollte von der abstrakten Musterobjektklasse abgeleitet sein:

//+------------------------------------------------------------------+
//| "Inside Bar" pattern class                                       |
//+------------------------------------------------------------------+
class CPatternInsideBar : public CPattern
  {
protected:
//--- Create the (1) image object, the appearance of the (2) info panel and (3) the bitmap object
   virtual bool      CreateBitmap(void);
   virtual void      CreateInfoPanelView(void);
   void              CreateBitmapView(void);
public:
//--- Return the flag of the pattern supporting the specified property
   virtual bool      SupportProperty(ENUM_PATTERN_PROP_INTEGER property)   { return true; }
   virtual bool      SupportProperty(ENUM_PATTERN_PROP_DOUBLE property)    { return true; }
   virtual bool      SupportProperty(ENUM_PATTERN_PROP_STRING property)    { return true; }
   
//--- Return description of the pattern (1) status and (2) type
   virtual string    StatusDescription(void) const { return CMessage::Text(MSG_LIB_TEXT_PATTERN_STATUS_PA);       }
   virtual string    TypeDescription(void)   const { return CMessage::Text(MSG_LIB_TEXT_PATTERN_TYPE_INSIDE_BAR); }

//--- Draw the pattern icon on the chart
   virtual void      Draw(const bool redraw);

//--- Constructor
                     CPatternInsideBar(const uint id,const string symbol,const ENUM_TIMEFRAMES timeframe,MqlRates &rates,const ENUM_PATTERN_DIRECTION direct);
  };


Im Klassenkonstruktor legen wir den Musternamen, die Anzahl der Musterbalken gleich zwei sowie die Anzahl der Balken der verschachtelten Formationen gleich 2 fest - keine verschachtelten Formationen:

//+------------------------------------------------------------------+
//| Constructor                                                      |
//+------------------------------------------------------------------+
CPatternInsideBar::CPatternInsideBar(const uint id,const string symbol,const ENUM_TIMEFRAMES timeframe,MqlRates &rates,const ENUM_PATTERN_DIRECTION direct) : 
   CPattern(PATTERN_STATUS_PA,PATTERN_TYPE_INSIDE_BAR,id,direct,symbol,timeframe,rates)
  {
   this.SetProperty(PATTERN_PROP_NAME,"Inside Bar");
   this.SetProperty(PATTERN_PROP_CANDLES,2);
   this.m_bars_formation=(int)this.GetProperty(PATTERN_PROP_CANDLES);
  }


Die virtuelle Methode, die das Aussehen der Infotafel bestimmt:

//+------------------------------------------------------------------+
//| Create the info panel appearance                                 |
//+------------------------------------------------------------------+
void CPatternInsideBar::CreateInfoPanelView(void)
  {
//--- If the form object is not created, leave

      return;

//--- Set the background and form frame colors
   this.m_form.SetBackgroundColor(this.m_color_panel_bidirect,true);
   this.m_form.SetBorderColor(clrGray,true);
//--- Create strings to describe the pattern, its parameters and search criteria
   string name=::StringFormat("Inside Bar (%lu bars)",int(this.Time()-this.MotherBarTime())/::PeriodSeconds(this.Timeframe())+1);
   string param=this.DirectDescription();//::StringFormat("%s (%.2f/%.2f/%.2f)",this.DirectDescription(),this.GetProperty(PATTERN_PROP_RATIO_BODY_TO_CANDLE_SIZE_CRITERION),this.GetProperty(PATTERN_PROP_RATIO_LARGER_SHADOW_TO_CANDLE_SIZE_CRITERION),this.GetProperty(PATTERN_PROP_RATIO_SMALLER_SHADOW_TO_CANDLE_SIZE_CRITERION));
//--- Set the coordinates of the panel and calculate its width and height depending on the size of the texts placed on the panel
   int x=3;
   int y=20;
   int w=4+(::fmax(20+this.m_form.TextWidth(name),::fmax(x+this.m_form.TextWidth(param),x+this.m_form.TextWidth(::TimeToString(this.Time())))));
   int h=2+(20+this.m_form.TextHeight(this.DirectDescription())+this.m_form.TextHeight(::TimeToString(this.Time())));
//--- Set the width and height of the panel according to the calculated values
   this.m_form.SetWidth(w);
   this.m_form.SetHeight(h);
//--- Depending on the chart size and coordinates, we calculate the coordinates of the panel so that it does not go beyond the chart
   int chart_w=(int)::ChartGetInteger(this.m_chart_id,CHART_WIDTH_IN_PIXELS);
   int chart_h=(int)::ChartGetInteger(this.m_chart_id,CHART_HEIGHT_IN_PIXELS);
   int cx=(this.m_form.RightEdge() >chart_w-1 ? chart_w-1-this.m_form.Width()  : this.m_form.CoordX());
   int cy=(this.m_form.BottomEdge()>chart_h-1 ? chart_h-1-this.m_form.Height() : this.m_form.CoordY());
   this.m_form.SetCoordX(cx);
   this.m_form.SetCoordY(cy);
//--- Fill the background with a gradient color
   this.m_form.Erase(clr,200,true,false);
//--- Draw the panel frame, an icon with (i), draw the header text with the proportions of a candle and separate the header with a horizontal line
   this.m_form.DrawFrameSimple(0,0,this.m_form.Width(),this.m_form.Height(),1,1,1,1,this.m_form.BorderColor(),200);
   this.m_form.DrawIconInfo(1,1,200);
   this.m_form.Text(20,3,name,clrBlack,200);
   this.m_form.DrawLine(1,18,this.m_form.Width()-1,18,clrDarkGray,250);
//--- Under the horizontal line, enter the pattern description with its search criteria and the date of the pattern-defining bar
   y=20;
   this.m_form.Text(x,y,param,clrBlack,200);
   y+=this.m_form.TextHeight(::TimeToString(this.Time()));
   this.m_form.Text(x,y,::TimeToString(this.Time()),clrBlack,200);
//--- Update the panel while redrawing the chart
   this.m_form.Update(true);
  }

Für jeden Mustertyp werden wir eigene virtuelle Methoden erstellen, um das Erscheinungsbild des Info-Panels zu gestalten, denn jedes Muster hat seine eigenen wichtigen Parameter, die auf dem Panel angezeigt werden können, um das Muster visuell zu beschreiben.


Die Methode, die das Mustersymbol auf dem Chart zeichnet:

//+------------------------------------------------------------------+
//| Draw the pattern icon on the chart                               |
//+------------------------------------------------------------------+
void CPatternInsideBar::Draw(const bool redraw)
  {
//--- If the flag for drawing with dots is set, call the parent class method and leave
   if(this.m_draw_dots)
     {
      CPattern::Draw(redraw);
      return;
     }
//--- If the bitmap object has not yet been created, create it
   if(this.m_bitmap==NULL)
     {
      if(!this.CreateBitmap())
         return;
     }
//--- display
   this.Show(redraw);
  }

Die Logik der Methode ist in den Kommentaren beschrieben. Die Methode der übergeordneten Klasse erstellt und zeichnet Musterbeschriftungen (Punkte) auf dem Chart. Wenn also das Flag zum Zeichnen von Punkten gesetzt ist, werden sie mit der Methode der Elternklasse gezeichnet.
Andernfalls wird das Bitmap-Objekt erstellt und im Chart angezeigt.


Die Methode, die das Bitmap-Objekt erstellt:

//+------------------------------------------------------------------+
//| Create the bitmap object                                         |
//+------------------------------------------------------------------+
bool CPatternInsideBar::CreateBitmap(void)
  {
//--- If the bitmap object has already been created earlier, return 'true'
   if(this.m_bitmap!=NULL)
      return true;
//--- Calculate the object coordinates and dimensions
   datetime time=this.MotherBarTime();
   double   price=(this.MotherBarHigh()+this.MotherBarLow())/2;
   int      w=this.GetBitmapWidth();
   int      h=this.GetBitmapHeight();
//--- Create the Bitmap object
   this.m_bitmap=this.CreateBitmap(this.ID(),this.GetChartID(),0,this.Name(),time,price,w,h,this.m_color_bidirect);
   if(this.m_bitmap==NULL)
      return false;
//--- Set the object origin to its center and remove the tooltip
   ::ObjectSetInteger(this.GetChartID(),this.m_bitmap.NameObj(),OBJPROP_ANCHOR,ANCHOR_CENTER);
   ::ObjectSetString(this.GetChartID(),this.m_bitmap.NameObj(),OBJPROP_TOOLTIP,"\n");
//--- Draw the bitmap object appearance
   this.CreateBitmapView();
   return true;
  }


Die Methode zur Erstellung das Aussehen des Bitmap-Objekts:

//+------------------------------------------------------------------+
//| Create the bitmap object appearance                              |
//+------------------------------------------------------------------+
void CPatternInsideBar::CreateBitmapView(void)
  {
   this.m_bitmap.Erase(CLR_CANV_NULL,0);
   int x=this.m_bitmap.Width()/2-int(1<<this.m_chart_scale)/2;
   this.m_bitmap.DrawRectangleFill(x,0,this.m_bitmap.Width()-1,this.m_bitmap.Height()-1,this.m_color_bidirect,80);
   this.m_bitmap.DrawRectangle(x,0,this.m_bitmap.Width()-1,this.m_bitmap.Height()-1,clrGray);
   this.m_bitmap.Update(false);
  }

Hier füllen wir den Hintergrund (canvas) mit einer transparenten Farbe und berechnen die anfängliche X-Koordinate des Rechtecks, das die Musterbalken umgibt. Dann füllen wir den rechteckigen Bereich, beginnend an der berechneten X-Koordinate, mit der für das bidirektionale Muster eingestellten Farbe und einer Deckkraft von 80, und umranden den gefüllten Bereich mit dem grauen Rechteck. Anschließend aktualisieren wir die Ressource, ohne das Chart neu zu zeichnen.


Jedes gesuchte Muster mit seinen Parametern wird durch das Objekt der Musterverwaltungsklasse kontrolliert und behandelt. Ein solches Objekt wird einmal erstellt, wenn die Erlaubnis erteilt wird, nach einem Muster mit dem angegebenen Typ und den angegebenen Mustersuchparametern zu suchen. In derselben Klasse müssen wir die Eigenschaften des Chartfensters auslesen - damit wir sie nur einmal beim Erstellen eines Steuerobjekts auslesen und dann die ausgelesenen Chartparameter in die erstellten Musterobjekte schreiben können. Charteigenschaften werden benötigt, um sicherzustellen, dass die Informationsfelder jedes einzelnen Musters nicht über den Rand des Charts hinausragen, wenn sie angezeigt werden. Wenn wir die Chartparameter jedes Mal auslesen, wenn wir ein neues Musterobjekt erstellen, wird das sehr ressourcenaufwändig - schließlich gibt es viele Muster in einer Zeitreihe. Außerdem, warum jedes Mal die gleichen Parameter lesen, wenn sie einmal gelesen und dann in jedem erstellten Muster verwendet werden können? Wir benötigen auch Chartparameter, wenn wir Bitmap-Objekte erstellen, die die Musterbalken umreißen. Auch hier ist es nicht optimal, jedes Mal dieselbe Größe in der Tabelle abzulesen. Daher werden wir sie nur lesen, wenn wir ein Mustersteuerungsobjekt erstellen. Allerdings gibt es hier eine Nuance: Wenn die Größe der Chart geändert wird, bleiben alle zuvor gelesenen Daten gleich, wie sie bereits empfangen wurden. Sie müssen erneut aus der Tabelle abgefragt und in den Eigenschaften der einzelnen Muster erfasst werden. Wir werden dies in den folgenden Artikeln tun.

Die Objektklasse der Mustersteuerung befindet sich in \MQL5\Include\DoEasy\Objects\Series\SeriesDE.mqh. Wir werden die notwendigen Änderungen daran vornehmen:

Die meisten Methoden müssen nicht vorgestellt werden - ihr Zweck ist in den Kommentaren beschrieben, und die Methoden setzen oder geben nur die entsprechenden Parameter des Klassenobjekts zurück. Wir übergeben nun der Mustersuchmethode eine Verknüpfung zur MqlRates-Struktur, in die wir die Daten des Mutterbalkens einfügen werden. Um diese Daten zu setzen, wird die Methode SetBarData() geschrieben, die den Zeiger auf ein Balkenobjekt und eine Verknüpfung zu einer Variablen vom Typ MqlRates erhält. Die variablen Felder enthalten die entsprechenden Eigenschaften des Balkenobjekts. Die Methode CreateAndRefreshPatternList() erhält die Mindestgröße des Kerzenkörpers. Anschließend werde ich die Einstellung dieses Wertes in das Mustersteuerungsobjekt aufnehmen. Der Wert wird an die Mustersuch- und Aktualisierungsmethode übergeben. Es geht darum, bei der Suche nach Mustern die Balken zu überspringen, deren Größe kleiner als dieser Wert ist. Für den Moment werden wir dort eine Null eingeben, wodurch dieser Filter deaktiviert wird.


Im Klassenkonstruktor berechnen wir die Chartdaten und schreiben sie in die neuen Klassenvariablen:

  }

      //--- Sort the list of all patterns by the unique pattern code
      this.m_list_all_patterns.Sort(SORT_BY_PATTERN_CODE);
      //--- search for a pattern in the list using a unique code
      int index=this.m_list_all_patterns.Search(&this.m_pattern_instance);
      //--- If there is no pattern equal to the sample in the list of all patterns
      if(index==WRONG_VALUE)
        {
         //--- Create the pattern object
         CPattern *pattern=this.CreatePattern(direction,this.m_list_all_patterns.Total(),bar);
         if(pattern==NULL)
            continue;
         //--- Sort the list of all patterns by time and insert the pattern into the list by its time
         this.m_list_all_patterns.Sort(SORT_BY_PATTERN_TIME);
         if(!this.m_list_all_patterns.InsertSort(pattern))
           {
            delete pattern;
            continue;
           }
         //--- Add the pattern to the list of bar object patterns
         bar.AddPattern(pattern.TypePattern());
         //--- Add the pointer to the bar the pattern object is found on, together with the mother bar data
         pattern.SetPatternBar(bar);
         pattern.SetMotherBarData(pattern_mother_bar_data);
         //--- set the chart data to the pattern object
         pattern.SetChartHeightInPixels(this.m_chart_height_px);
         pattern.SetChartScale(this.m_chart_scale);
         pattern.SetChartPriceMax(this.m_chart_price_max);
         pattern.SetChartPriceMin(this.m_chart_price_min);
         //--- If the drawing flag is set, draw the pattern label on the chart
         if(this.m_drawing)
            pattern.Draw(false);
        }
     }
//--- Sort the list of all patterns by time and return the total number of patterns in the list
   this.m_list_all_patterns.Sort(SORT_BY_PATTERN_TIME);
   return m_list_all_patterns.Total();
  }

Nun erhält die Methode die Mindestgröße des Balkenkörpers des gewünschten Musters. Wir übergeben der Mustersuchmethode die Größe und den Verweis auf die Struktur des Hauptbalkens, der die Balkenparameter enthalten soll. Wenn das Muster gefunden wird, wird der Typ des gefundenen Musters in das Balkenobjekt geschrieben, in dem das Muster gefunden wurde. Gleichzeitig erhält das auf dem Balken befindliche Musterobjekt den Zeiger auf den Balken, die Daten des Mutterbalkens und die Daten des Charts.


Die Methode, die das Flag für das Zeichnen von Mustersymbolen als Punkte setzt:

//+------------------------------------------------------------------+
//| Set the flag for drawing pattern icons as dots                   |
//+------------------------------------------------------------------+
void CPatternControl::SetDrawingAsDots(const bool flag,const bool redraw)
  {
   this.m_draw_dots=flag;
//--- Get a list of patterns controlled by the control object
   CArrayObj *list=this.GetListPatterns();
   if(list==NULL || list.Total()==0)
      return;
//--- In a loop by the list of patterns,
   for(int i=list.Total()-1;i>=0;i--)
     {
      //--- get the next pattern object
      CPattern *obj=list.At(i);
      if(obj==NULL)
         continue;
      //--- Set the flag value. If 'false', remove the pattern dot object
      obj.SetDrawAsDots(flag);
      if(!flag)
         obj.DeleteGraphObj();
      //--- Display the pattern label on the chart if the flag is 'true'
      else
         obj.Draw(false);
     }
//--- At the end of the cycle, redraw the chart if the flag is set
   if(redraw)
      ::ChartRedraw(this.m_chart_id);
  }

Die Methodenlogik wurde in den Codekommentaren ausführlich beschrieben. Hier erhalten wir die Liste der Muster, die von diesem Kontrollobjekt verwaltet werden. In jedem Musterobjekt geben wir das Flag für das Zeichnen mit Punkten an. Wenn das Flag zurückgesetzt ist, müssen wir den zuvor gezeichneten Punkt löschen, und wenn das Flag gesetzt ist, sollten wir ihn zeichnen. Am Ende der Bearbeitung der Schleife aller Muster in der Liste und wenn ein Redrawing-Flag an die Methode übergeben wird, wird das Chart neu gezeichnet.


Als Nächstes müssen wir die Klasse des Musters „Pin-Bar“ ändern. Wir integrieren die Variable MqlRates in die Mustersuchmethode, um die Daten für den Mutterbalken festzulegen:

//+------------------------------------------------------------------+
//| Pin Bar pattern control class                                    |
//+------------------------------------------------------------------+
class CPatternControlPinBar : public CPatternControl
  {
protected:
//--- (1) Search for a pattern, return direction (or -1),
//--- (2) create a pattern with a specified direction,
//--- (3) create and return a unique pattern code
//--- (4) return the list of patterns managed by the object
   virtual ENUM_PATTERN_DIRECTION FindPattern(const datetime series_bar_time,const uint min_body_size,MqlRates &mother_bar_data) const;
   virtual CPattern *CreatePattern(const ENUM_PATTERN_DIRECTION direction,const uint id,CBar *bar);
   virtual ulong     GetPatternCode(const ENUM_PATTERN_DIRECTION direction,const datetime time) const
                       {
                        //--- unique pattern code = candle opening time + type + status + pattern direction + timeframe + timeseries symbol
                        return(time+PATTERN_TYPE_PIN_BAR+PATTERN_STATUS_PA+direction+this.Timeframe()+this.m_symbol_code);
                       }
   virtual CArrayObj*GetListPatterns(void);
//--- Create object ID based on pattern search criteria
   virtual ulong     CreateObjectID(void);

public:
//--- Parametric constructor
                     CPatternControlPinBar(const string symbol,const ENUM_TIMEFRAMES timeframe,
                                           CArrayObj *list_series,CArrayObj *list_patterns,
                                           const double ratio_body_to_candle_size,
                                           const double ratio_larger_shadow_to_candle_size,
                                           const double ratio_smaller_shadow_to_candle_size) :
                        CPatternControl(symbol,timeframe,PATTERN_STATUS_PA,PATTERN_TYPE_PIN_BAR,list_series,list_patterns)
                       {
                        this.m_ratio_body_to_candle_size=ratio_body_to_candle_size;
                        this.m_ratio_larger_shadow_to_candle_size=ratio_larger_shadow_to_candle_size;
                        this.m_ratio_smaller_shadow_to_candle_size=ratio_smaller_shadow_to_candle_size;
                        this.m_object_id=this.CreateObjectID();
                       }
  };


In der Methode, die das Muster mit der angegebenen Richtung erstellt, fügen wir der Variablen MqlRates schreibende Balkendaten hinzu:

//+---------------------------------------------------------------------+
//| CPatternControlPinBar::Create a pattern with a specified direction  |
//+---------------------------------------------------------------------+
CPattern *CPatternControlPinBar::CreatePattern(const ENUM_PATTERN_DIRECTION direction,const uint id,CBar *bar)
  {
//--- If invalid indicator is passed to the bar object, return NULL
   if(bar==NULL)
      return NULL;
//--- Fill the MqlRates structure with bar data
   MqlRates rates={0};
   this.SetBarData(bar,rates);
//--- Create a new Pin Bar pattern
   CPatternPinBar *obj=new CPatternPinBar(id,this.Symbol(),this.Timeframe(),rates,direction);
   if(obj==NULL)
      return NULL;
//--- set the proportions of the candle the pattern was found on to the properties of the created pattern object
   obj.SetProperty(PATTERN_PROP_RATIO_BODY_TO_CANDLE_SIZE,bar.RatioBodyToCandleSize());
   obj.SetProperty(PATTERN_PROP_RATIO_LOWER_SHADOW_TO_CANDLE_SIZE,bar.RatioLowerShadowToCandleSize());
   obj.SetProperty(PATTERN_PROP_RATIO_UPPER_SHADOW_TO_CANDLE_SIZE,bar.RatioUpperShadowToCandleSize());

   obj.SetProperty(PATTERN_PROP_RATIO_SMALLER_SHADOW_TO_CANDLE_SIZE_CRITERION,this.RatioSmallerShadowToCandleSizeValue());
//--- Set the control object ID to the pattern object
   obj.SetProperty(PATTERN_PROP_CTRL_OBJ_ID,this.ObjectID());
//--- Return the pointer to a created object
   return obj;
  }

Zuvor haben wir hier die Daten Element für Element eingegeben. Jetzt wird diese elementweise Eingabe in der Methode SetBarData() durchgeführt, die die gleiche ist, aber der Methodencode ist kürzer.


In der Methode, die nach dem Muster sucht, fügen wir die Eingabedaten zu dem Balkendaten-Mutterbalken hinzu, in dem das Muster gefunden wurde:

//+------------------------------------------------------------------+

//--- If the list is empty, return -1

      return WRONG_VALUE;

     {

      if(bar!=NULL)
        {
         this.SetBarData(bar,mother_bar_data);
         return PATTERN_DIRECTION_BULLISH;
        }

        {
         this.SetBarData(bar,mother_bar_data);

        }
     }

   return WRONG_VALUE;
  }

Da es sich beim „Pin-Bar“ um eine Formation aus einem Balken handelt, ist der Mutterbalken auch der Basisbalken, auf dem das Muster gefunden wurde.


Erstellen wir die Klasse zur Verwaltung des Musters „Inside-Bar“. Die Struktur dieses Musters ist streng definiert und hat keine weiteren Parameter, außer dass sich der Basisbalken (rechts) vollständig innerhalb des Mutterbalkens (links) befinden muss. Es gibt keine weiteren Parameter. Daher ist jedes „Inside-Bar“-Muster das einzige Muster in einer Zeitreihe, im Gegensatz zum „Pin-Bar“-Muster, bei dem wir die Parameter für die Suche festlegen können, und es kann mehrere „Pin-Bar“-Muster mit unterschiedlichen Parametern in einer Zeitreihe geben. Für jedes dieser Muster wird ein eigenes Kontrollobjekt erstellt. In Anbetracht der obigen Ausführungen wird für das Muster „Inside-Bar“ immer nur ein Kontrollobjekt für jede Zeitreihe erstellt.

Tragen wir die neue Klasse zur Verwaltung des Musters „Inside-Bar“ in derselben Datei nach der Kontrollklasse für das Muster „Pin-Bar“ ein:

//+------------------------------------------------------------------+
//| Inside Bar pattern control class                                 |
//+------------------------------------------------------------------+
class CPatternControlInsideBar : public CPatternControl
  {

                           return false;

                       }
   bool              FindMotherBar(CArrayObj *list,MqlRates &rates) const
                       {
                        bool res=false;
                        if(list==NULL)
                           return false;
                        //--- In a loop through the list, starting from the bar to the left of the base one
                        for(int i=list.Total()-2;i>0;i--)
                          {
                           //--- Get the pointers to two consecutive bars 
                           CBar *bar0=list.At(i);
                           CBar *bar1=list.At(i-1);
                           if(bar0==NULL || bar1==NULL)
                              return false;
                           //--- If the obtained bars represent a pattern

                             {

                              this.SetBarData(bar1,rates);
                              res=true;
                             }
                           //--- If there is no pattern, interrupt the loop
                           else
                              break;
                          }

                       }
  };

Die Klasse ist praktisch eine Kopie der Klasse des Musters „Pin-Bar“, die im vorherigen Artikel über die Bibliotheksmuster beschrieben wurde. Im Klassenkonstruktor setzen wir alle Kriterien für die Mustersuche auf Null, da sie hier nicht verwendet werden. Die Objekt-ID ist immer Null, da dies das einzige Objekt in einer Zeitreihe ist:

//+------------------------------------------------------------------+
//| Create object ID based on pattern search criteria                |
//+------------------------------------------------------------------+
ulong CPatternControlInsideBar::CreateObjectID(void)
  {
   return 0;
  }


Die wichtigsten Methoden der Mustersuche sind der Vergleich zweier benachbarter Balken auf das Vorhandensein des Musters und die Suche nach dem Mutterbalken:

//--- Check and return the presence of a pattern on two adjacent bars
   bool              CheckInsideBar(const CBar *bar1,const CBar *bar0) const
                       {
                        //--- If empty bar objects are passed, return 'false'
                        if(bar0==NULL || bar1==NULL)
                           return false;
                        //--- Return the fact that the bar on the right is completely within the dimensions of the bar on the left
                        return(bar0.High()<bar1.High() && bar0.Low()>bar1.Low());
                       }
   bool              FindMotherBar(CArrayObj *list,MqlRates &rates) const
                       {
                        bool res=false;
                        if(list==NULL)
                           return false;
                        //--- In a loop through the list, starting from the bar to the left of the base one
                        for(int i=list.Total()-2;i>0;i--)
                          {
                           //--- Get the pointers to two consecutive bars 
                           CBar *bar0=list.At(i);
                           CBar *bar1=list.At(i-1);
                           if(bar0==NULL || bar1==NULL)
                              return false;
                           //--- If the obtained bars represent a pattern 
                           if(CheckInsideBar(bar1,bar0))
                             {
                              //--- set mother bar data to the MqlRates variable and set 'res' to 'true'
                              this.SetBarData(bar1,rates);
                              res=true;
                             }
                           //--- If there is no pattern, interrupt the loop
                           else
                              break;
                          }
                        //--- return the result
                        return res;
                       }

Die Mustersuchmethode vergleicht einfach die Größen zweier benachbarter Balken und gibt das Flag zurück, dass der rechte Balken vollständig innerhalb des linken liegt.

Bei der Suche nach dem Mutterbalken wird in einer Schleife durch die Liste der Balken nach Mustern gesucht, und wenn ein Muster gefunden wird, werden die Balkendaten in die Variable MqlRates geschrieben, und die Suche wird mit dem nächsten Balkenpaar fortgesetzt. Die Suche wird so lange fortgesetzt, bis bei jeder Iteration der Schleife Muster gefunden werden, und die Daten des Mutterbalkens werden in eine Variable aus jedem nachfolgenden Balken geschrieben. Auf diese Weise finden wir alle verschachtelten Muster und erhalten schließlich die Daten des Hauptbalkens aus dem ganz linken Balken der gesamten Sequenz.


Die Methode, die das Muster mit der angegebenen Richtung erstellt:

//+-----------------------------------------------------------------------+
//|CPatternControlInsideBar::Create a pattern with the specified direction|
//+-----------------------------------------------------------------------+
CPattern *CPatternControlInsideBar::CreatePattern(const ENUM_PATTERN_DIRECTION direction,const uint id,CBar *bar)
  {
//--- If invalid indicator is passed to the bar object, return NULL
   if(bar==NULL)
      return NULL;
//--- Fill the MqlRates structure with bar data
   MqlRates rates={0};
   this.SetBarData(bar,rates);
//--- Create a new Inside Bar pattern
   CPatternInsideBar *obj=new CPatternInsideBar(id,this.Symbol(),this.Timeframe(),rates,PATTERN_DIRECTION_BOTH);
   if(obj==NULL)
      return NULL;
//--- set the proportions of the candle the pattern was found on to the properties of the created pattern object
   obj.SetProperty(PATTERN_PROP_RATIO_BODY_TO_CANDLE_SIZE,bar.RatioBodyToCandleSize());
   obj.SetProperty(PATTERN_PROP_RATIO_LOWER_SHADOW_TO_CANDLE_SIZE,bar.RatioLowerShadowToCandleSize());
   obj.SetProperty(PATTERN_PROP_RATIO_UPPER_SHADOW_TO_CANDLE_SIZE,bar.RatioUpperShadowToCandleSize());
//--- set the search criteria of the candle the pattern was found on to the properties of the created pattern object
   obj.SetProperty(PATTERN_PROP_RATIO_BODY_TO_CANDLE_SIZE_CRITERION,this.RatioBodyToCandleSizeValue());
   obj.SetProperty(PATTERN_PROP_RATIO_LARGER_SHADOW_TO_CANDLE_SIZE_CRITERION,this.RatioLargerShadowToCandleSizeValue());
   obj.SetProperty(PATTERN_PROP_RATIO_SMALLER_SHADOW_TO_CANDLE_SIZE_CRITERION,this.RatioSmallerShadowToCandleSizeValue());
//--- Set the control object ID to the pattern object
   obj.SetProperty(PATTERN_PROP_CTRL_OBJ_ID,this.ObjectID());
//--- Return the pointer to a created object
   return obj;
  }

Die Methode erstellt einfach ein neues Objekt der Musterklasse „Inside-Bar“ und gibt das Ergebnis der Erstellung des neuen Objekts zurück. Alles unterhalb der Zeichenketten für die Erstellung eines neuen Objekts sind immer noch nutzlose Zuweisungen von Nullen an Objekteigenschaften, die bereits im Klassenkonstruktor zugewiesen werden. Aber im Moment ist das alles noch übrig. Später kann es notwendig sein, die Verwendung einiger Parameter zur Identifizierung des Musters hinzuzufügen. Wenn nicht, dann werde ich den zusätzlichen Code einfach entfernen.


Die Methode zur Suche nach dem Muster:

   if(list==NULL || list.Total()==0)
      return WRONG_VALUE;
//--- Sort the list by bar opening time

   for(int i=list.Total()-2;i>=0;i--)
     {
      CBar *bar_prev=list.At(i);
      if(bar_prev==NULL)
         return WRONG_VALUE;
      //--- check that the resulting two bars are a pattern. If not, return -1
      if(!this.CheckInsideBar(bar_prev,bar_patt))
         return WRONG_VALUE;
      //--- If the pattern is found at the previous step, look for nested patterns.
      //--- The leftmost bar will be the mother bar for the entire chain of nested patterns
      //--- If the found pattern does not have nested ones, then its mother bar will be the current cycle bar (to the left of the base one)
      if(!this.FindMotherBar(list,mother_bar_data))
         SetBarData(bar_prev,mother_bar_data);
//--- Return the pattern direction (bidirectional)
      return PATTERN_DIRECTION_BOTH;
     }
//--- No patterns found - return -1
   return WRONG_VALUE;
  }

Die Logik der Methode ist in den Kommentaren beschrieben. Die Eröffnungszeit des aktuellen Balkens wird an die Methode übergeben. Holt die Liste aller Balken außer dem aktuellen Balken (wir suchen nicht nach Mustern auf dem Null-Balken). In der Schleife, die auf der resultierenden Liste der Balken basiert, werden alle zwei benachbarten Balken daraufhin überprüft, ob sie die Kriterien des Musters erfüllen. Wenn ihre Beziehung ein Muster ist, suchen wir nach verschachtelten Mustern, d. h. wir suchen in einer zusätzlichen Schleife nach benachbarten Mustern, bis sie gefunden werden. Auf diese Weise finden wir die gesamte Kette benachbarter Muster, und das am weitesten links liegende - sein linker Balken - wird der Mutterbalken für die gesamte Kette verschachtelter Muster sein. Dieser Balken, seine Zeit und die Preise werden in die Eigenschaften des gefundenen Musters geschrieben. Diese Daten geben uns die Möglichkeit, die gesamte Kette der verschachtelten Muster vollständig einzurahmen, wenn wir sie auf dem Chart anzeigen, der im Test-EA sichtbar sein wird.


Die Methode gibt eine Liste von Mustern zurück, die von dem Objekt verwaltet werden:

//+------------------------------------------------------------------+
//| Returns the list of patterns managed by the object               |

Passen wir in der Klasse des Muster-Managements die Methode an, die das Objekt „Inner Bar“ des der Musterkontrolle zurückgibt:

                        return NULL;
                       }

Zuvor gab die Methode NULL zurück, da die Klasse des von der Methode zurückgegebenen Objekts noch nicht erstellt worden war.


Passen wir die Methode an, die das Flag für die Verwendung des Musters „Inside-Bar“ setzt und ein Steuerelementobjekt erstellt, wenn es noch nicht vorhanden ist:

//--- Set the flag for using the Pattern Inside and create a control object if it does not already exist
   void              SetUsedPatternInsideBar(const bool flag)
                       {
                        //--- Get the pointer to the Inner Bar pattern control object 
                        CPatternControlInsideBar *obj=this.GetObjControlPatternInsideBar();
                        //--- If the pointer is received (the object exists), set the use flag 
                        if(obj!=NULL)
                           obj.SetUsed(flag);
                        //--- f there is no object and the flag is passed as 'true'
                        else if(flag)
                          {
                           //--- Create the new Inside Bar pattern control object
                           obj=new CPatternControlInsideBar(this.Symbol(),this.Timeframe(),this.m_list_series,this.m_list_all_patterns);
                           if(obj==NULL)
                              return;
                           //--- Add pointer to the created object to the list
                           if(!this.m_list_controls.Add(obj))
                             {
                              delete obj;
                              return;
                             }
                           //--- Set the usage flag and pattern parameters to the control object
                           obj.SetUsed(flag);
                           obj.SetRatioBodyToCandleSizeValue(0);
                           obj.SetRatioLargerShadowToCandleSizeValue(0);
                           obj.SetRatioSmallerShadowToCandleSizeValue(0);
                           obj.CreateAndRefreshPatternList(0);
                          }
                       }

Zuvor war die Methode aus dem oben genannten Grund leer. Die Logik der Methode ist im Code kommentiert und bedarf kaum einer zusätzlichen Erklärung.

In den folgenden Artikeln werden wir Chartparameter verfolgen, um Charteigenschaften in Zeitreihenobjekten zurückzusetzen, die zum Zeichnen von Mustersymbolen verwendet werden. Alle Eigenschaften aller im Terminal geöffneten Charte sind in der Chartsammlung der Bibliothek enthalten. Damit wir von der Zeitreihensammlung aller Symbole aus Zugriff auf die Daten dieser Sammlung haben, müssen wir den Zeiger auf die Chartsammlung an die Zeitreihensammlung übergeben.
Zu diesem Zweck verbinden wir die Datei der Chartsammlung mit der Datei \MQL5\Include\DoEasy\Collections\TimeSeriesCollection.mqh. Außerdem deklarieren wir den Zeiger auf die Chartsammlung im privaten Abschnitt:

Ich habe ähnliche Methoden in einem früheren Artikel entwickelt, wo sie ausführlicher beschrieben wurden. Im Grunde ist alles ganz einfach: Wir holen uns den Zeiger auf das gewünschte Symbol Zeitreihe und geben das Ergebnis der gleichnamigen Methode auf die erhaltene Zeitreihe zurück. Dort wiederum wird der Zeiger auf die gewünschte Zeitreihe des Chartzeitraums auf genau die gleiche Weise erhalten. Die erforderliche Kontrollmethode wird vom Zeitreihenmuster-Kontrollobjekt aufgerufen, dessen Zeiger von der Methode zurückgegeben wird, die wiederum von der erwähnten Zeitreihe aufgerufen wird - die Kette funktioniert, bis das gewünschte Ergebnis erreicht ist. Das Design ist verschachtelt und unpraktisch in Bezug auf die Menge an identischen Codes. Später werde ich versuchen, ihn zu verkürzen, indem ich den Zugriff auf die erforderlichen Objekte anders gestalte.

Das Gleiche muss mit der Hauptklasse der CEngine-Bibliothek in \MT5\MQL5\Include\DoEasy\Engine.mqh gemacht werden.

Wir ersetzen in allen Methoden zur Behandlung von Mustern die gleichen oder ähnliche Zeichenketten von Eingaben

CArrayObj *list=this.GetListPatterns(symbol,timeframe);

mit den folgenden:

CArrayObj *list=this.GetListPatterns(CorrectSymbol(symbol),CorrectTimeframe(timeframe));

Hier haben wir die in den Methodenparametern übergebenen Werte für das Symbol und die Chartperiode durch die zu Beginn des Artikels implementierten Funktionen zur Anpassung dieser Parameter ersetzt.

Die Methoden rufen die entsprechenden Methoden der oben implementierten Zeitreihensammlungsklasse auf.


Im selben Abschnitt implementieren wir die Methode, mit der wir die Infotafeln aller Muster ausblenden, außer denen, die sich zur angegebenen Balkenzeit befinden:

//--- Hides info panels of all patterns except the specified one
   void                 SeriesPatternHideAllInfoPanelsExceptOne(const ulong pattern_code,const bool redraw=false)
                          {
                           CArrayObj *list=CSelect::ByPatternProperty(this.GetListAllPatterns(),PATTERN_PROP_CODE,pattern_code,NO_EQUAL);
                           if(list==NULL)
                              return;
                           for(int i=list.Total()-1;i>=0;i--)
                             {
                              CPattern *obj=list.At(i);
                              if(obj!=NULL)
                                 obj.HideInfoPanel();
                             }
                           if(redraw)
                              ::ChartRedraw();
                          }
//--- Hide info panels of all patterns except those at the specified time of the bar
   void                 SeriesPatternHideAllInfoPanelsExceptBarTime(const datetime bar_time,const bool redraw=false)
                          {
                           CArrayObj *list=CSelect::ByPatternProperty(this.GetListAllPatterns(),PATTERN_PROP_TIME,bar_time,NO_EQUAL);
                           if(list==NULL)
                              return;
                           for(int i=list.Total()-1;i>=0;i--)
                             {
                              CPattern *obj=list.At(i);
                              if(obj!=NULL)
                                 obj.HideInfoPanel();
                             }
                           if(redraw)
                              ::ChartRedraw();
                          }

Hier erhalten wir aus der Liste aller Muster eine Liste derjenigen Muster, die nicht auf dem Balken mit der angegebenen Eröffnungszeit liegen. In der Schleife holen wir uns dann den Zeiger auf das nächste Musterobjekt aus der resultierenden Liste und blenden sein Informationsfeld aus. Am Ende des Zyklus wird das Chart neu gezeichnet, wenn das Redraw-Flag gesetzt ist.


Fügen wir die Übergabe des Zeigers auf die Chartsammlung in die Methode ein, die die Zeiger auf alle erforderlichen Sammlungen an die Handelsklasse und die Sammelklasse übergibt:

//--- Play a sound by its description
   bool                 PlaySoundByDescription(const string sound_description);

//--- Pass the pointers to all the necessary collections to the trading class and the indicator buffer collection class
   void                 CollectionOnInit(void)
                          {
                           this.m_trading.OnInit(this.GetAccountCurrent(),this.m_symbols.GetObject(),this.m_market.GetObject(),this.m_history.GetObject(),this.m_events.GetObject());
                           this.m_buffers.OnInit(this.m_time_series.GetObject(),this.m_indicators.GetObject());
                           this.m_time_series.OnInit(this.GetChartObjCollection());
                          }
//--- Set the spread multiplier for symbol trading objects in the symbol collection
   void                 SetSpreadMultiplier(const uint value=1,const string symbol=NULL)  { this.m_trading.SetSpreadMultiplier(value,symbol);   }


Erstellen wir in der Ereignisbehandlung der DoEasy-Bibliothek ein Leerzeichen für die Behandlung von Chartsammlungsereignissen:

//--- Handling market watch window events
   else if(idx>MARKET_WATCH_EVENT_NO_EVENT && idx<SYMBOL_EVENTS_NEXT_CODE)
     {
      //--- Market Watch window event
      string descr=this.GetMWEventDescription((ENUM_MW_EVENT)idx);
      string name=(idx==MARKET_WATCH_EVENT_SYMBOL_SORT ? "" : ": "+sparam);
      Print(TimeMSCtoString(lparam)," ",descr,name);
     }

//--- Handle chart events
   else if(idx>CHART_OBJ_EVENT_NO_EVENT && idx<CHART_OBJ_EVENTS_NEXT_CODE)
     {
      
     }
     
//--- Handling timeseries events
   else if(idx>SERIES_EVENTS_NO_EVENT && idx<SERIES_EVENTS_NEXT_CODE)
     {

Anschließend werde ich hier Handler für die Größenänderung des Charts und die Übergabe neuer Werte an die Zeitreihensammlung und von dort an die Musterobjekte hinzufügen.

Jetzt ist alles bereit für die Prüfung der Ergebnisse.

Wenn true, werden alle gefundenen Muster als Punkte auf dem Chart gezeichnet. Wenn false, werden die „Inside-Bar“-Muster mit Bitmap-Objekten gezeichnet - die Musterbalken werden mit farbigen Rechtecken umrandet.

Die Logik des Codes ist in den Kommentaren beschrieben. Wir müssen die Öffnungszeit des Balkens ermitteln, über dem sich der Mauszeiger befindet. Auf der Grundlage der Öffnungszeit erhalten wir das Balkenobjekt, aus dem wir die Liste der erkannten Muster „herausziehen“.
Dann zeigen wir einfach die Infotafeln der einzelnen gefundenen Muster auf dem Bildschirm an.

Kompilieren Sie den EA und starten Sie ihn auf einem Chart:


Wie wir sehen können, funktioniert alles wie vorgesehen. Das Zeichnen von Mustern als Bilder kann zu Verzögerungen führen. Wir werden uns später damit befassen.

Wir sehen das verschachtelte Muster ungefähr in der Mitte des Bildschirms. Wenn Sie den Mauszeiger bewegen und das Informationsfenster erscheint, wird die Gesamtzahl der in der Musterkette enthaltenen Balken angezeigt.

Auf der rechten Seite des Bildschirms werden zwei Muster auf einem Balken gebildet - „Pin-Bar“ und „Inside-Bar“. Die Infotafeln der beiden Muster werden übereinander angezeigt.


Was kommt als Nächstes?

Im nächsten Artikel werde ich mit der Entwicklung von Zeitreihenmustern fortfahren.

Alle erstellten Dateien sind dem Artikel beigefügt und können zum Selbststudium und für Tests heruntergeladen werden.

Zeitreihen-Clustering für kausales Schlussfolgern Zeitreihen-Clustering für kausales Schlussfolgern
Clustering-Algorithmen beim maschinellen Lernen sind wichtige unüberwachte Lernalgorithmen, die die ursprünglichen Daten in Gruppen mit ähnlichen Beobachtungen unterteilen können. Anhand dieser Gruppen können Sie den Markt für ein bestimmtes Cluster analysieren, anhand neuer Daten nach den stabilsten Clustern suchen und kausale Schlüsse ziehen. In dem Artikel wird eine originelle Methode für das Clustering von Zeitreihen in Python vorgeschlagen.
Matrix-Faktorisierung: Die Grundlagen Matrix-Faktorisierung: Die Grundlagen
Da das Ziel hier didaktisch ist, werden wir so einfach wie möglich vorgehen. Das heißt, wir werden nur das implementieren, was wir brauchen: Matrixmultiplikation. Sie werden heute sehen, dass dies ausreicht, um die Matrix-Skalar-Multiplikation zu simulieren. Die größte Schwierigkeit, auf die viele Menschen bei der Implementierung von Code mit Matrixfaktorisierung stoßen, ist folgende: Im Gegensatz zur skalaren Faktorisierung, bei der in fast allen Fällen die Reihenfolge der Faktoren das Ergebnis nicht verändert, ist dies bei der Verwendung von Matrizen nicht der Fall.

Entwicklung eines Replay Systems (Teil 45): Chart Trade Projekt (IV) Entwicklung eines Replay Systems (Teil 45): Chart Trade Projekt (IV)
Der Hauptzweck dieses Artikels ist die Einführung und Erläuterung der Klasse C_ChartFloatingRAD. Wir haben einen Chart Trade-Indikator, der auf recht interessante Weise funktioniert. Wie Sie vielleicht bemerkt haben, haben wir immer noch eine relativ kleine Anzahl von Objekten im Chart, und dennoch erhalten wir die erwartete Funktionalität. Die im Indikator enthaltenen Werte können bearbeitet werden. Die Frage ist, wie ist das möglich? Dieser Artikel wird die Dinge etwas klarer machen.
