Similarities and differences of the account types
To track netting account events, we need to understand the differences between hedging and netting accounts.
The differences relate to representation of positions. A hedging account allows us to open any number of positions on a single symbol, while a
netting account allows for only one. A hedging account allows closing a position by a volume of an oppositely directed position.
In this case:
- If the volume of the opposite position is smaller than the volume of the closed position, then the opposite position is closed completely, while the closed position is eliminated partially,
- If the volume of the opposite position is higher than the volume of the closed position, then the opposite position is closed partially, while the closed position is eliminated in full,
- if the two positions have equal volumes, both are closed;
- Each position has an ID equal to the opening order's ticket. This ID does not change during the entire position lifetime;
- Each position has its own ticket equal to the ticket of the order which led to the position opening;
- If we send a request to open a new position in the current position direction, a new position with a new ID and ticket is opened.
On a netting account, working with one position on one symbol excludes the possibility of closing a position by an opposite one. However, in a remotely similar situation (when an oppositely directed order is activated), this position can be closed either partially or in full, or change its direction:
- If the volume of an activated opposite order is less than the current position one, the position is closed partially,
- If the volume of an activated opposite order is equal to the current position one, the position is closed in full,
- If the volume of an activated opposite order exceeds the current position one, the position changes its direction (reversal),
- Each position has an ID equal to the opening order's ticket. This ID does not change during the entire position lifetime;
- Each position has a ticket equal to the ticket of the order which led to the position reversal. The ticket may differ from the ID. To some extent, it repeats the tickets of multiple positions on a hedge account;
- If we send a request to open a new position in the current position direction, a volume of an activated order is added to the volume of the
current position. The position ticket is not changed.
Implementing event handling on a netting account
To track netting account events, we will simply divide handling position events by account types. This increases the amount of code but clarifies the logic due to separating the functionality. We will optimize the code and get rid of all redundancies later — after debugging and confirming steady operation.
When adding new constants to the event type enumerations, I noticed that sorting sometimes works incorrectly. Checking the reasons for such a behavior revealed that the two main factors are event/order properties matching the sorting by this type and their location in the enumeration regardless of the fact that each constant is numbered. For example, if a property is not used for searching, it should be skipped and correct numbers should be assigned to search method enumeration constants. Additionally, event/order properties not used in sorting should also be placed at the end of the property type list. To calculate the initial number of the following property types, the number of unused properties within the amount of previous type properties should be subtracted from the initial property types index.
To verify the creation of sorting method enumerations, a small function was added to the DELib.mqh service functions file:
//+------------------------------------------------------------------+ //| Display all sorting enumeration constants in the journal | //+------------------------------------------------------------------+ void EnumNumbersTest() { string enm="ENUM_SORT_ORDERS_MODE"; string t=StringSubstr(enm,5,5)+"BY"; Print("Search of the values of the enumaration ",enm,":"); ENUM_SORT_ORDERS_MODE type=0; while(StringFind(EnumToString(type),t)==0) { Print(enm,"[",type,"]=",EnumToString(type)); if(type>500) break; type++; } Print("\nNumber of members of the ",enm,"=",type); } //+------------------------------------------------------------------+
To check the contents of a specific sorting types enumeration, it should be entered manually in two function strings (I did not find a way to automatically set a certain enumeration in the ENUM_SORT_ORDERS_MODE type=0; string).
Now, if we call this function in the test EA's OnInit() handler, all constant names of a specified enumeration and the corresponding indices
are displayed in the journal.
When checking the enumerations, I detected that they were created incorrectly. To fix this, I slightly modified the enumerations in the Defines.mqh
file.
I set a different order of constants in the enumerations — properties
not used in sorting are placed at the end of the constant list for object properties enumeration. Also, macro
substitutions for specifying the number of unused properties for searching and sorting should be added. These macro
substitutions are to be
used when calculating initial property indices in sorting enumerations
leading to calculation of correct indices of initial constants in enumerations.
Also, new constant types for events on netting accounts
and
constants for storing the magic number and an opposite position symbol for hedge accounts
should be added.
Orders and positions are often required to be grouped, so that a group of selected orders and positions can be handled simultaneously. The
library allows implementing this by simply adding a group ID to the abstract order property. This makes it possible to arrange any orders and
positions having a similar ID into a single list and work with a selected group.
Such an ID was added to order properties and order sorting lists.

The group ID is to be set to zero by default. To achieve this, set the order property value to zero in the closed constructor of the COrder class:

After these changes, you can assign a group ID to any order/position, thus arranging orders and positions into certain groups to work with a specific group only. 0 is assigned by default to all newly opened positions and set orders. However, you are able to assign another group to any order/position using the SetGroupID(group_index) method. Besides, you can find out any order's group using the GroupID() method.
Let's return to implementing event tracking on a netting account.
In order to divide the functionality by account
types, we are going to add a class member variable to the private section of the CEvent abstract event class in the
Event.mqh file:
protected: ENUM_TRADE_EVENT m_trade_event; // Trading event bool m_is_hedge; // Hedge account flag long m_chart_id; // Control program chart ID int m_digits_acc; // Number of decimal places for the account currency long m_long_prop[EVENT_PROP_INTEGER_TOTAL]; // Event integer properties double m_double_prop[EVENT_PROP_DOUBLE_TOTAL]; // Event real properties string m_string_prop[EVENT_PROP_STRING_TOTAL]; // Event string properties //--- return the flag presence in the trading event bool IsPresentEventFlag(const int event_code) const { return (this.m_event_code & event_code)==event_code; }
Add declaration of methods returning
(for a hedge account) magic
number and a symbol of an opposite
position,
(for considering a position reversal on a netting account) previous
position's order type and ticket, current position's order ticket,
position type and ticket before changing direction, position
type and ticket after changing direction to the list of methods with simplified access of the class' public section:
//+------------------------------------------------------------------+ //| Methods of simplified access to event object properties | //+------------------------------------------------------------------+ //--- Return (1) event type, (2) event time in milliseconds, (3) event status, (4) event reason, (5) deal type, (6) deal ticket, //---(7) order type, based on which a deal was executed, (8) position opening order type, (9) position last order ticket, //--- (10) position first order ticket, (11) position ID, (12) opposite position ID, (13) magic number, (14) opposite position magic number, (15) position open time ENUM_TRADE_EVENT TypeEvent(void) const { return (ENUM_TRADE_EVENT)this.GetProperty(EVENT_PROP_TYPE_EVENT); } long TimeEvent(void) const { return this.GetProperty(EVENT_PROP_TIME_EVENT); } ENUM_EVENT_STATUS Status(void) const { return (ENUM_EVENT_STATUS)this.GetProperty(EVENT_PROP_STATUS_EVENT); } ENUM_EVENT_REASON Reason(void) const { return (ENUM_EVENT_REASON)this.GetProperty(EVENT_PROP_REASON_EVENT); } ENUM_DEAL_TYPE TypeDeal(void) const { return (ENUM_DEAL_TYPE)this.GetProperty(EVENT_PROP_TYPE_DEAL_EVENT); } long TicketDeal(void) const { return this.GetProperty(EVENT_PROP_TICKET_DEAL_EVENT); } ENUM_ORDER_TYPE TypeOrderEvent(void) const { return (ENUM_ORDER_TYPE)this.GetProperty(EVENT_PROP_TYPE_ORDER_EVENT); } ENUM_ORDER_TYPE TypeFirstOrderPosition(void) const { return (ENUM_ORDER_TYPE)this.GetProperty(EVENT_PROP_TYPE_ORDER_POSITION); } long TicketOrderEvent(void) const { return this.GetProperty(EVENT_PROP_TICKET_ORDER_EVENT); } long TicketFirstOrderPosition(void) const { return this.GetProperty(EVENT_PROP_TICKET_ORDER_POSITION); } long PositionID(void) const { return this.GetProperty(EVENT_PROP_POSITION_ID); } long PositionByID(void) const { return this.GetProperty(EVENT_PROP_POSITION_BY_ID); } long Magic(void) const { return this.GetProperty(EVENT_PROP_MAGIC_ORDER); } long MagicCloseBy(void) const { return this.GetProperty(EVENT_PROP_MAGIC_BY_ID); } long TimePosition(void) const { return this.GetProperty(EVENT_PROP_TIME_ORDER_POSITION); } //--- When changing position direction, return (1) previous position order type, (2) previous position order ticket, //--- (3) current position order type, (4) current position order ticket, //--- (5) position type and (6) ticket before changing direction, (7) position type and (8) ticket after changing direction ENUM_ORDER_TYPE TypeOrderPosPrevious(void) const { return (ENUM_ORDER_TYPE)this.GetProperty(EVENT_PROP_TYPE_ORD_POS_BEFORE); } long TicketOrderPosPrevious(void) const { return (ENUM_ORDER_TYPE)this.GetProperty(EVENT_PROP_TICKET_ORD_POS_BEFORE); } ENUM_ORDER_TYPE TypeOrderPosCurrent(void) const { return (ENUM_ORDER_TYPE)this.GetProperty(EVENT_PROP_TYPE_ORD_POS_CURRENT); } long TicketOrderPosCurrent(void) const { return (ENUM_ORDER_TYPE)this.GetProperty(EVENT_PROP_TICKET_ORD_POS_CURRENT);} ENUM_POSITION_TYPE TypePositionPrevious(void) const { return PositionTypeByOrderType(this.TypeOrderPosPrevious()); } ulong TicketPositionPrevious(void) const { return this.TicketOrderPosPrevious(); } ENUM_POSITION_TYPE TypePositionCurrent(void) const { return PositionTypeByOrderType(this.TypeOrderPosCurrent()); } ulong TicketPositionCurrent(void) const { return this.TicketOrderPosCurrent(); } //--- Return (1) the price the event occurred at, (2) open price, (3) close price, //--- (4) StopLoss price, (5) TakeProfit price, (6) profit, (7) requested order volume, //--- (8) executed order volume, (9) remaining order volume, (10) executed position volume double PriceEvent(void) const { return this.GetProperty(EVENT_PROP_PRICE_EVENT); } double PriceOpen(void) const { return this.GetProperty(EVENT_PROP_PRICE_OPEN); } double PriceClose(void) const { return this.GetProperty(EVENT_PROP_PRICE_CLOSE); } double PriceStopLoss(void) const { return this.GetProperty(EVENT_PROP_PRICE_SL); } double PriceTakeProfit(void) const { return this.GetProperty(EVENT_PROP_PRICE_TP); } double Profit(void) const { return this.GetProperty(EVENT_PROP_PROFIT); } double VolumeOrderInitial(void) const { return this.GetProperty(EVENT_PROP_VOLUME_ORDER_INITIAL); } double VolumeOrderExecuted(void) const { return this.GetProperty(EVENT_PROP_VOLUME_ORDER_EXECUTED); } double VolumeOrderCurrent(void) const { return this.GetProperty(EVENT_PROP_VOLUME_ORDER_CURRENT); } double VolumePositionExecuted(void) const { return this.GetProperty(EVENT_PROP_VOLUME_POSITION_EXECUTED); } //--- Return the (1) symbol and (2) opposite position symbol string Symbol(void) const { return this.GetProperty(EVENT_PROP_SYMBOL); } string SymbolCloseBy(void) const { return this.GetProperty(EVENT_PROP_SYMBOL_BY_ID); } //+------------------------------------------------------------------+
The methods are simple: the appropriate event property is returned for orders, a ticket of the order which opened or changed a position is
returned for tickets, while a position type (by type of the order, which triggered it) is returned for type name using the previously
described
PositionTypeByOrderType() function from the DELib.mqh service function file.
Set saving data on the account type in the class constructor:
//+------------------------------------------------------------------+ //| Constructor | //+------------------------------------------------------------------+ CEvent::CEvent(const ENUM_EVENT_STATUS event_status,const int event_code,const ulong ticket) : m_event_code(event_code) { this.m_long_prop[EVENT_PROP_STATUS_EVENT] = event_status; this.m_long_prop[EVENT_PROP_TICKET_ORDER_EVENT] = (long)ticket; this.m_is_hedge=bool(::AccountInfoInteger(ACCOUNT_MARGIN_MODE)==ACCOUNT_MARGIN_MODE_RETAIL_HEDGING); this.m_digits_acc=(int)::AccountInfoInteger(ACCOUNT_CURRENCY_DIGITS); this.m_chart_id=::ChartID(); } //+------------------------------------------------------------------+
Add the definition of methods returning a name of the order a deal event has
happened for, the very first (opening) position order, an
order, which led to opening (netting, hedging) or changing (netting) the current position, name
of the current position type, type of the order which led to opening the
previous position and the previous position type name
to the event property description methods:
//+------------------------------------------------------------------+ //| Descriptions of order object properties | //+------------------------------------------------------------------+ //--- Get description of an order's (1) integer, (2) real and (3) string properties string GetPropertyDescription(ENUM_EVENT_PROP_INTEGER property); string GetPropertyDescription(ENUM_EVENT_PROP_DOUBLE property); string GetPropertyDescription(ENUM_EVENT_PROP_STRING property); //--- Return the event's (1) status and (2) type string StatusDescription(void) const; string TypeEventDescription(void) const; //--- Return the name of an (1) event deal order, (2) position's parent order, (3) current position order and the (4) current position //--- Return the name of an (5) order and (6) position before the direction was changed string TypeOrderDealDescription(void) const; string TypeOrderFirstDescription(void) const; string TypeOrderEventDescription(void) const; string TypePositionCurrentDescription(void) const; string TypeOrderPreviousDescription(void) const; string TypePositionPreviousDescription(void) const; //--- Return the name of the deal/order/position reason string ReasonDescription(void) const;
and their implementation beyond the class body as well:
//+------------------------------------------------------------------+ //| Return the name of the order/position/deal | //+------------------------------------------------------------------+ string CEvent::TypeOrderDealDescription(void) const { ENUM_EVENT_STATUS status=this.Status(); return ( status==EVENT_STATUS_MARKET_PENDING || status==EVENT_STATUS_HISTORY_PENDING ?

PositionTypeDescription((ENUM_POSITION_TYPE)this.GetProperty(EVENT_PROP_TYPE_DEAL_EVENT)) : status==EVENT_STATUS_BALANCE ? DealTypeDescription((ENUM_DEAL_TYPE)this.GetProperty(EVENT_PROP_TYPE_DEAL_EVENT)) : TextByLanguage("Неизвестный тип ордера","Unknown order type") ); } //+------------------------------------------------------------------+ //| Return the name of the position's first order | //+------------------------------------------------------------------+ string CEvent::TypeOrderFirstDescription(void) const { return OrderTypeDescription((ENUM_ORDER_TYPE)this.GetProperty(EVENT_PROP_TYPE_ORDER_POSITION)); } //+------------------------------------------------------------------+ //| Return the name of the order that changed the position | //+------------------------------------------------------------------+ string CEvent::TypeOrderEventDescription(void) const { return OrderTypeDescription(this.TypeOrderEvent()); } //+------------------------------------------------------------------+ //| Return the name of the current position | //+------------------------------------------------------------------+ string CEvent::TypePositionCurrentDescription(void) const { return PositionTypeDescription(this.TypePositionCurrent()); } //+------------------------------------------------------------------+ //| Return the name of the order before changing the direction | //+------------------------------------------------------------------+ string CEvent::TypeOrderPreviousDescription(void) const { return OrderTypeDescription(this.TypeOrderPosPrevious()); } //+------------------------------------------------------------------+ //| Return the name of the position before changing the direction | //+------------------------------------------------------------------+ string CEvent::TypePositionPreviousDescription(void) const { return PositionTypeDescription(this.TypePositionPrevious()); } //+------------------------------------------------------------------+
These methods are simple, just like the ones returning order and position types. The only difference is in the functions from the DELib.mqh file returning the type of orders and positions as their type description: PositionTypeDescription() and OrderTypeDescription().
Now, the ReasonDescription() method should be improved for considering and returning descriptions of newly added enumerations related to event reasons for a netting account:
//+------------------------------------------------------------------+ //| Return the name of the deal/order/position reason | //+------------------------------------------------------------------+ string CEvent::ReasonDescription(void) const { ENUM_EVENT_REASON reason=this.Reason(); return ( reason==EVENT_REASON_ACTIVATED_PENDING ?

In the fifth part of the library description, we have already developed
the method decoding a trading event code. Let's recall its logic:
An event code is passed to the method and the event code flags are then checked. If the code has the checked flag, the appropriate trading event is set. Since the event code may have multiple flags, all possible flags for the event are checked and the event type is defined from their combination. Next, the event type is added to the appropriate class variable and is entered in the property of the event object (EVENT_PROP_TYPE_EVENT).
Now we simply need to add tracking new flags matching possible netting account events in the trading event code:
//+------------------------------------------------------------------+ //| Decode the event code and set a trading event | //+------------------------------------------------------------------+ void CEvent::SetTypeEvent(void) { //--- Pending order placed (check for matching the event code since there can only be one flag here) if(this.m_event_code==TRADE_EVENT_FLAG_ORDER_PLASED) { this.m_trade_event=TRADE_EVENT_PENDING_ORDER_PLASED; this.SetProperty(EVENT_PROP_TYPE_EVENT,this.m_trade_event); return; } //--- Pending order removed (check for matching the event code since there can only be one flag here) if(this.m_event_code==TRADE_EVENT_FLAG_ORDER_REMOVED) { this.m_trade_event=TRADE_EVENT_PENDING_ORDER_REMOVED; this.SetProperty(EVENT_PROP_TYPE_EVENT,this.m_trade_event); return; } //--- Position opened (Check the presence of multiple flags in the event code) if(this.IsPresentEventFlag(TRADE_EVENT_FLAG_POSITION_OPENED)) { //--- If an existing position is changed if(this.IsPresentEventFlag(TRADE_EVENT_FLAG_POSITION_CHANGED)) { //--- If the pending order is activated by a price if(this.IsPresentEventFlag(TRADE_EVENT_FLAG_ORDER_ACTIVATED)) { //--- If this is a position reversal if(this.IsPresentEventFlag(TRADE_EVENT_FLAG_POSITION_REVERSE)) { //--- check the partial closure flag and set the //--- "position reversal by activation of a pending order" or "position reversal by partial activation of a pending order" trading event this.m_trade_event= ( !this.IsPresentEventFlag(TRADE_EVENT_FLAG_PARTIAL) ?

The entire logic is quite simple and commented in the code. Therefore, I am not going to dwell on the <if-else> method.

Since the differences of hedging and netting accounts are evident only when working with positions, the CEventPositionOpen and CEventPositionClose derived classes of the CEvent abstract class require fine-tuning — only methods of displaying event messages to the journal are refined. The remaining methods of the classes remain unchanged.
Open the EventPositionOpen.mqh file and add the private method creating and returning a short event description:
//+------------------------------------------------------------------+ //| Position open event | //+------------------------------------------------------------------+ class CEventPositionOpen : public CEvent { private: //--- Create and return a short event message string EventsMessage(void); public: //--- Constructor CEventPositionOpen(const int event_code,const ulong ticket=0) : CEvent(EVENT_STATUS_MARKET_POSITION,event_code,ticket) {} //--- Supported (1) real and (2) integer order properties virtual bool SupportProperty(ENUM_EVENT_PROP_INTEGER property); virtual bool SupportProperty(ENUM_EVENT_PROP_DOUBLE property); //--- (1) Display a short event message in the journal, (2) Send an event to the chart virtual void PrintShort(void); virtual void SendEvent(void); }; //+------------------------------------------------------------------+
Let's write its implementation outside the class body:
//+------------------------------------------------------------------+ //| Create and return a short event message | //+------------------------------------------------------------------+ string CEventPositionOpen::EventsMessage(void) { //--- number of decimal places in an event symbol quote int digits=(int)::SymbolInfoInteger(this.Symbol(),SYMBOL_DIGITS); //--- (1) header, (2) executed order volume, (3) executed position volume, (4) event price, //--- (5) StopLoss price, (6) TakeProfit price, (7) magic number, (6) profit in account currency string head="- "+this.TypeEventDescription()+": "+TimeMSCtoString(this.TimePosition())+" -\n"; string vol_ord=::DoubleToString(this.VolumeOrderExecuted(),DigitsLots(this.Symbol())); string vol_pos=::DoubleToString(this.VolumePositionExecuted(),DigitsLots(this.Symbol())); string price=TextByLanguage(" по цене "," at price ")+::DoubleToString(this.PriceEvent(),digits); string sl=(this.PriceStopLoss()>0 ? ", sl "+ ::DoubleToString(this.PriceStopLoss(),digits) : ""); string tp=(this.PriceTakeProfit()>0 ? ", tp "+ ::DoubleToString(this.PriceTakeProfit(),digits) : ""); string magic=(this.Magic()!=0 ? TextByLanguage(", магик ",", magic ")+(string)this.Magic() : ""); string profit=TextByLanguage(", профит ",", profit ")+::DoubleToString(this.Profit(),this.m_digits_acc)+" "+::AccountInfoString(ACCOUNT_CURRENCY); //--- string text=""; //--- Position reversal if(this.GetProperty(EVENT_PROP_REASON_EVENT)<EVENT_REASON_ACTIVATED_PENDING) { //--- EURUSD: Buy #xx changed to 0.1 Sell #xx (0.2 SellLimit order #XX) at х.ххххх, sl х.ххххх, tp x.xxxxx, magic, profit xxxx text= ( this.Symbol()+" "+ this.TypePositionPreviousDescription()+" #"+(string)this.TicketPositionPrevious()+ TextByLanguage(" изменен на "," turned to ")+vol_pos+" "+this.TypePositionCurrentDescription()+" #"+(string)this.TicketPositionCurrent()+ " ["+vol_ord+" "+this.TypeOrderEventDescription()+" #"+(string)this.TicketOrderEvent()+" ]"+price+sl+tp+magic+profit ); } else { //--- Add volume if(this.GetProperty(EVENT_PROP_TICKET_ORDER_EVENT)!=this.GetProperty(EVENT_PROP_POSITION_ID)) { //--- EURUSD: Added 0.1 to Buy #xx (BuyLimit order #XX) at х.ххххх, magic text= ( this.Symbol()+" "+ TextByLanguage("Добавлено ","Added ")+vol_ord+TextByLanguage(" к "," to ")+ this.TypePositionCurrentDescription()+" #"+(string)this.TicketPositionCurrent()+ " ["+vol_ord+" "+this.TypeOrderEventDescription()+" #"+(string)this.TicketOrderEvent()+" ]"+price+magic ); } //--- Open a position else { //--- EURUSD: Opened 0.1 Buy #xx (BuyLimit order #XX) at х.ххххх, sl х.ххххх, tp x.xxxxx, magic text= ( this.Symbol()+" "+ TextByLanguage("Открыт ","Open ")+vol_pos+" "+ this.TypePositionCurrentDescription()+" #"+(string)this.TicketPositionCurrent()+ " ["+vol_ord+" "+this.TypeOrderEventDescription()+" #"+(string)this.TicketOrderEvent()+" ]"+price+sl+tp+magic ); } } return head+text; } //+------------------------------------------------------------------+
The method creates message variants depending on the event status and the presence of certain event object properties.
For example, if
StopLoss is set, "sl" header and its price are added to the text. Otherwise, an empty string is inserted instead of a StopLoss entry. The same
is done to some other event properties. The comments of the method listing contain the
conditions of creating an event text, as well as examples
of a text returned by the method.
The text created in the method is displayed in the journal from the PrintShort() method, which in turn is called from the Refresh() method in the event collection class by calling the virtual method SendEvent() of the CEvent class redefined here in the CEventPositionOpen class.

All event object classes were changed for new tasks of working on netting accounts.
Now let's deal with the
CEventCollection event collection class.
Previously, the CreateNewEvent() method (described in the fifth part)
featured a local variable for storing a trading event code.
Let's make it a private class member by removing it from the new event creation method and declaring in
the private class section. Also, add declarations of the necessary methods of creating a new event for hedging
and netting account types, the method for returning the list of
all InOut deals by position ID and the method for obtaining a market position
object by its ID.
//+------------------------------------------------------------------+ //| Collection of account events | //+------------------------------------------------------------------+ class CEventsCollection : public CListObj { private: CListObj m_list_events; // List of events bool m_is_hedge; // Hedge account flag long m_chart_id; // Control program chart ID int m_trade_event_code; // Trading event code ENUM_TRADE_EVENT m_trade_event; // Account trading event CEvent m_event_instance; // Event object for searching by property //--- Create a trading event depending on the order status void CreateNewEvent(COrder* order,CArrayObj* list_history,CArrayObj* list_market); //--- Create an event for a (1) hedging account, (2) netting account void NewDealEventHedge(COrder* deal,CArrayObj* list_history,CArrayObj* list_market); void NewDealEventNetto(COrder* deal,CArrayObj* list_history,CArrayObj* list_market); //--- Select and return the list of market pending orders CArrayObj* GetListMarketPendings(CArrayObj* list); //--- Select from the list and return the list of historical (1) removed pending orders, (2) deals, (3) all closing orders CArrayObj* GetListHistoryPendings(CArrayObj* list); CArrayObj* GetListDeals(CArrayObj* list); CArrayObj* GetListCloseByOrders(CArrayObj* list); //--- Return the list of (1) all position orders by its ID, (2) all deal positions by its ID //--- (3) all market entry deals by position ID, (4) all market exit deals by position ID, //--- (5) all position reversal deals by position ID CArrayObj* GetListAllOrdersByPosID(CArrayObj* list,const ulong position_id); CArrayObj* GetListAllDealsByPosID(CArrayObj* list,const ulong position_id); CArrayObj* GetListAllDealsInByPosID(CArrayObj* list,const ulong position_id); CArrayObj* GetListAllDealsOutByPosID(CArrayObj* list,const ulong position_id); CArrayObj* GetListAllDealsInOutByPosID(CArrayObj* list,const ulong position_id); //--- Return the total volume of all deals (1) IN, (2) OUT of the position by its ID double SummaryVolumeDealsInByPosID(CArrayObj* list,const ulong position_id); double SummaryVolumeDealsOutByPosID(CArrayObj* list,const ulong position_id); //--- Return the (1) first, (2) last and (3) closing order from the list of all position orders, //--- (4) an order by ticket, (5) market position by ID, //--- (6) the last and (7) penultimate InOut deal by position ID COrder* GetFirstOrderFromList(CArrayObj* list,const ulong position_id); COrder* GetLastOrderFromList(CArrayObj* list,const ulong position_id); COrder* GetCloseByOrderFromList(CArrayObj* list,const ulong position_id); COrder* GetHistoryOrderByTicket(CArrayObj* list,const ulong order_ticket); COrder* GetPositionByID(CArrayObj* list,const ulong position_id); //--- Return the flag of the event object presence in the event list bool IsPresentEventInList(CEvent* compared_event); public: //--- Select events from the collection with time within the range from begin_time to end_time CArrayObj *GetListByTime(const datetime begin_time=0,const datetime end_time=0); //--- Return the full event collection list "as is" CArrayObj *GetList(void) { return &this.m_list_events; } //--- Return the list by selected (1) integer, (2) real and (3) string properties meeting the compared criterion CArrayObj *GetList(ENUM_EVENT_PROP_INTEGER property,long value,ENUM_COMPARER_TYPE mode=EQUAL) { return CSelect::ByEventProperty(this.GetList(),property,value,mode); } CArrayObj *GetList(ENUM_EVENT_PROP_DOUBLE property,double value,ENUM_COMPARER_TYPE mode=EQUAL) { return CSelect::ByEventProperty(this.GetList(),property,value,mode); } CArrayObj *GetList(ENUM_EVENT_PROP_STRING property,string value,ENUM_COMPARER_TYPE mode=EQUAL) { return CSelect::ByEventProperty(this.GetList(),property,value,mode); } //--- Update the list of events void Refresh(CArrayObj* list_history, CArrayObj* list_market, const bool is_history_event, const bool is_market_event, const int new_history_orders, const int new_market_pendings, const int new_market_positions, const int new_deals); //--- Set the control program chart ID void SetChartID(const long id) { this.m_chart_id=id; } //--- Return the last trading event on the account ENUM_TRADE_EVENT GetLastTradeEvent(void) const { return this.m_trade_event; } //--- Reset the last trading event void ResetLastTradeEvent(void) { this.m_trade_event=TRADE_EVENT_NO_EVENT; } //--- Constructor CEventsCollection(void); }; //+------------------------------------------------------------------+
Reset the trading event code in the class constructor's initialization list:
//+------------------------------------------------------------------+ //| Constructor | //+------------------------------------------------------------------+ CEventsCollection::CEventsCollection(void) : m_trade_event(TRADE_EVENT_NO_EVENT),m_trade_event_code(TRADE_EVENT_FLAG_NO_EVENT) { this.m_list_events.Clear(); this.m_list_events.Sort(SORT_BY_EVENT_TIME_EVENT); this.m_list_events.Type(COLLECTION_EVENTS_ID); this.m_is_hedge=bool(::AccountInfoInteger(ACCOUNT_MARGIN_MODE)==ACCOUNT_MARGIN_MODE_RETAIL_HEDGING); this.m_chart_id=::ChartID(); } //+------------------------------------------------------------------+
A netting account may experience multiple trading actions. It may have only one position undergoing changes on a single symbol. They may include changing the volume in case of partial closing triggered by activation of an opposite order having a lesser volume, as well as adding a volume to the position when orders in the same direction are triggered.
The most interesting changes, however, happen to a position when opposite orders having greater volume are
triggered. In this case, a new ticket is assigned to a position. The ticket corresponds to a triggered order, and the position type is changed
to the opposite one (position reversal). The position ID remains unchanged and is equal to the ticket of the very first order that triggered
the position on the account.
We need to track all position direction changes throughout its lifetime in order to (1) correctly display position reversal entries
in the journal and (2) have the ability to obtain data on position reversal events in our programs. To achieve this, we need to have access to
all its deals having the DEAL_ENTRY_INOUT position change method from the
ENUM_DEAL_ENTRY enumeration.
In this case, we only need to arrange such deals sequentially by time of their occurrence and take a necessary deal. The deal itself features all order properties that triggered it.
Thus, if we have a deal order, we can receive a ticket for a position with a changed direction, as well as type of an order, which triggered a position reversal, along with new StopLoss and TakeProfit levels, etc. All we need to get such functionality is to create a list of all InOut deals by its ID, which is very easy to do using the library we develop.Let's consider the method for receiving all InOut deals of a position by its ID:
//+------------------------------------------------------------------+ //| Return the list of all reversal deals (IN_OUT) | //| by a position ID | //+------------------------------------------------------------------+ CArrayObj* CEventsCollection::GetListAllDealsInOutByPosID(CArrayObj *list,const ulong position_id) { if(list.Type()!=COLLECTION_HISTORY_ID) { Print(DFUN,TextByLanguage("Ошибка. Список не является списком исторической коллекции","Error. The list is not a list of the history collection")); return NULL; } CArrayObj* list_deals=this.GetListAllDealsByPosID(list,position_id); list_deals=CSelect::ByOrderProperty(list_deals,ORDER_PROP_DEAL_ENTRY,DEAL_ENTRY_INOUT,EQUAL); return list_deals; } //+------------------------------------------------------------------+
Check the type of the list passed to the method. If it is not a historical orders and deals collection one, warn about the error and return NULL.
We need all these checks of lists in the classes to detect our own errors. They are to be removed after debugging not to burden the calculations with unnecessary checks.
Next, we receive the list of deals by position ID (the method was considered in the previous article), sort the obtained list by InOut position change method and return the final list.
To receive data on an open position or define its absence, create a method receiving a market position object by its ID:
//+------------------------------------------------------------------+ //| Return a position by ID | //+------------------------------------------------------------------+ COrder* CEventsCollection::GetPositionByID(CArrayObj *list,const ulong position_id) { if(list.Type()!=COLLECTION_MARKET_ID) { Print(DFUN,TextByLanguage("Ошибка. Список не является списком рыночной коллекции","Error. The list is not a list of the market collection")); return NULL; } CArrayObj* list_orders=CSelect::ByOrderProperty(list,ORDER_PROP_STATUS,ORDER_STATUS_MARKET_POSITION,EQUAL); list_orders=CSelect::ByOrderProperty(list_orders,ORDER_PROP_POSITION_ID,position_id,EQUAL); if(list_orders==NULL || list_orders.Total()==0) return NULL; COrder* order=list_orders.At(0); return(order!=NULL ? order : NULL); } //+------------------------------------------------------------------+
The method is simple, just like other similar methods from the library. Check
the type of a selected list. If it is not a list of market orders and positions collection, warn about the error and return NULL.
Next, take only active position objects from the list passed to the method
and
sort it by position ID passed to the method.
If
failed to obtain the list or it has no objects, return NULL—
there is no requested position.
Next, receive a single market position object from the list
(there can only be one position with a specified ID in the market) and return
either the object itself or
NULL in case receiving it ended in an error.
The method of creating a new CreateNewEvent() event object was described in the previous
article.
Here I will only show implemented changes.
The following local variable has been removed from the method
int trade_event_code
It has become a member of the class we created in the private section.
The method logic remains the same but now it also features calling the necessary methods for handling the type of the account we are working on. If it is hedging, the method of creating a new event for a hedging account is called. Otherwise, the method of creating a new event for a netting account is used:
//+------------------------------------------------------------------+ //| Create a trading event depending on the order status | //+------------------------------------------------------------------+ void CEventsCollection::CreateNewEvent(COrder* order,CArrayObj* list_history,CArrayObj* list_market) { this.m_trade_event_code=TRADE_EVENT_FLAG_NO_EVENT; ENUM_ORDER_STATUS status=order.Status(); //--- Pending order placed if(status==ORDER_STATUS_MARKET_PENDING) { this.m_trade_event_code=TRADE_EVENT_FLAG_ORDER_PLASED; CEvent* event=new CEventOrderPlased(this.m_trade_event_code,order.Ticket()); if(event!=NULL) { event.SetProperty(EVENT_PROP_TIME_EVENT,order.TimeOpenMSC()); // Event time event.SetProperty(EVENT_PROP_REASON_EVENT,EVENT_REASON_DONE); // Event reason (from the ENUM_EVENT_REASON enumeration) event.SetProperty(EVENT_PROP_TYPE_DEAL_EVENT,order.TypeOrder()); // Event deal type event.SetProperty(EVENT_PROP_TICKET_DEAL_EVENT,order.Ticket()); // Event order ticket event.SetProperty(EVENT_PROP_TYPE_ORDER_EVENT,order.TypeOrder()); // Event order type event.SetProperty(EVENT_PROP_TYPE_ORDER_POSITION,order.TypeOrder()); // Event order type event.SetProperty(EVENT_PROP_TICKET_ORDER_EVENT,order.Ticket()); // Event order ticket event.SetProperty(EVENT_PROP_TICKET_ORDER_POSITION,order.Ticket()); // Order ticket event.SetProperty(EVENT_PROP_POSITION_ID,order.PositionID()); // Position ID event.SetProperty(EVENT_PROP_POSITION_BY_ID,order.PositionByID()); // Opposite position ID event.SetProperty(EVENT_PROP_MAGIC_BY_ID,order.Magic()); // Opposite position magic number event.SetProperty(EVENT_PROP_TYPE_ORD_POS_BEFORE,order.TypeOrder()); // Position order type before changing direction event.SetProperty(EVENT_PROP_TICKET_ORD_POS_BEFORE,order.Ticket()); // Position order ticket before changing direction event.SetProperty(EVENT_PROP_TYPE_ORD_POS_CURRENT,order.TypeOrder()); // Current position order type event.SetProperty(EVENT_PROP_TICKET_ORD_POS_CURRENT,order.Ticket()); // Current position order ticket event.SetProperty(EVENT_PROP_MAGIC_ORDER,order.Magic()); // Order magic number event.SetProperty(EVENT_PROP_TIME_ORDER_POSITION,order.TimeOpenMSC()); // Order time event.SetProperty(EVENT_PROP_PRICE_EVENT,order.PriceOpen()); // Event price event.SetProperty(EVENT_PROP_PRICE_OPEN,order.PriceOpen()); // Order price event.SetProperty(EVENT_PROP_PRICE_CLOSE,order.PriceClose()); // Order close price event.SetProperty(EVENT_PROP_PRICE_SL,order.StopLoss()); // StopLoss order price event.SetProperty(EVENT_PROP_PRICE_TP,order.TakeProfit()); // TakeProfit order price event.SetProperty(EVENT_PROP_VOLUME_ORDER_INITIAL,order.Volume()); // Requested order volume event.SetProperty(EVENT_PROP_VOLUME_ORDER_EXECUTED,order.Volume()-order.VolumeCurrent()); // Executed order volume event.SetProperty(EVENT_PROP_VOLUME_ORDER_CURRENT,order.VolumeCurrent()); // Remaining (unexecuted) order volume event.SetProperty(EVENT_PROP_VOLUME_POSITION_EXECUTED,0); // Executed position volume event.SetProperty(EVENT_PROP_PROFIT,order.Profit()); // Profit event.SetProperty(EVENT_PROP_SYMBOL,order.Symbol()); // Order symbol event.SetProperty(EVENT_PROP_SYMBOL_BY_ID,order.Symbol()); // Opposite position symbol //--- Set control program chart ID, decode the event code and set the event type event.SetChartID(this.m_chart_id); event.SetTypeEvent(); //--- Add the event object if it is not in the list if(!this.IsPresentEventInList(event)) { this.m_list_events.InsertSort(event); //--- Send a message about the event and set the value of the last trading event event.SendEvent(); this.m_trade_event=event.TradeEvent(); } //--- If the event is already present in the list, remove a new event object and display a debugging message else { ::Print(DFUN_ERR_LINE,TextByLanguage("Такое событие уже есть в списке","This event already in the list.")); delete event; } } } //--- Pending order removed if(status==ORDER_STATUS_HISTORY_PENDING) { this.m_trade_event_code=TRADE_EVENT_FLAG_ORDER_REMOVED; CEvent* event=new CEventOrderRemoved(this.m_trade_event_code,order.Ticket()); if(event!=NULL) { ENUM_EVENT_REASON reason= ( order.State()==ORDER_STATE_CANCELED ?

The CreateNewEvent(), NewDealEventHedge() and NewDealEventNetto() methods have identical logic and actions. So, it would be reasonable to combine them. But so far we have done as displayed above (on a "simple-to-complex" basis). As I have already mentioned, the codes of the classes and their methods are to be optimized later.
We have implemented the changes in the events collection class for working on hedging and netting account types. The full listing of the
class is provided in the library files attached below. The code is quite bulky.
Testing the performance on hedging and netting accounts
To check the implemented changes, create a test EA based on the one from the previous
article.
Save it in the new \MQL5\Experts\TestDoEasy\Part06 directory under the name TestDoEasyPart06.mq5.
Remove the strings checking the account type from the EA's OnInit() handler:
int OnInit() { //--- Check account type if(!engine.IsHedge()) { Alert(TextByLanguage("Ошибка. Счёт должен быть хеджевым","Error. Account must be hedge")); return INIT_FAILED; } //--- set global variables
Instead, add calling the function of checking the validity of creating enumerations for searching and sorting by object properties:
int OnInit() { //--- Calling the function displays the list of enumeration constants in the journal //--- (the list is set in the strings 22 and 25 of the DELib.mqh file) for checking the constants validity //EnumNumbersTest(); //--- set global variables
In order to close a position partially, a netting account requires placing a position that is opposite to the direction of the existing one
and has the volume sufficient for a partial closing. Therefore, we need to make slight corrections in the PressButtonEvents() button
pressing event handler function.
To partially close a Buy position:
//--- If the BUTT_CLOSE_BUY2 button is pressed: Close the half of the Buy with the maximum profit else if(button==EnumToString(BUTT_CLOSE_BUY2)) { //--- Get the list of all open positions CArrayObj* list=engine.GetListMarketPosition(); //--- Select only Buy positions from the list list=CSelect::ByOrderProperty(list,ORDER_PROP_TYPE,POSITION_TYPE_BUY,EQUAL); //--- Sort the list by profit considering commission and swap list.Sort(SORT_BY_ORDER_PROFIT_FULL); //--- Get the index of the Buy position with the maximum profit int index=CSelect::FindOrderMax(list,ORDER_PROP_PROFIT_FULL); if(index>WRONG_VALUE) { COrder* position=list.At(index); if(position!=NULL) { //--- Calculate the closed volume and close the half of the Buy position by the ticket if(engine.IsHedge()) trade.PositionClosePartial(position.Ticket(),NormalizeLot(position.Symbol(),position.Volume()/2.0)); else trade.Sell(NormalizeLot(position.Symbol(),position.Volume()/2.0)); } } }
Check the account. If hedging, close part of the position, otherwise (if netting) — send a Sell position open order with a volume equal to the half of the current Buy position volume.
To close part of a Sell position:
//--- If the BUTT_CLOSE_SELL2 button is pressed: Close the half of the Sell with the maximum profit else if(button==EnumToString(BUTT_CLOSE_SELL2)) { //--- Get the list of all open positions CArrayObj* list=engine.GetListMarketPosition(); //--- Select only Sell positions from the list list=CSelect::ByOrderProperty(list,ORDER_PROP_TYPE,POSITION_TYPE_SELL,EQUAL); //--- Sort the list by profit considering commission and swap list.Sort(SORT_BY_ORDER_PROFIT_FULL); //--- Get the index of the Sell position with the maximum profit int index=CSelect::FindOrderMax(list,ORDER_PROP_PROFIT_FULL); if(index>WRONG_VALUE) { COrder* position=list.At(index); if(position!=NULL) { //--- Calculate the closed volume and close the half of the Sell position by the ticket if(engine.IsHedge()) trade.PositionClosePartial(position.Ticket(),NormalizeLot(position.Symbol(),position.Volume()/2.0)); else trade.Buy(NormalizeLot(position.Symbol(),position.Volume()/2.0)); } } }
Check the account. If hedging, close part of the position, otherwise (if netting) — send a Buy position open order with a volume equal to the half of the current Sell position volume.
These are the necessary changes that should be implemented to make the EA work on a netting account.

Compile the EA, launch it on a hedging account and try the buttons:
Short messages about account events are displayed in the journal, while the chart comment describes the last event that occurred on the account.
Now let's switch to the netting account and launch the test:
In this case, the journal contains entries related to position events that are possible on a netting account only — now new positions are
opened, the EA works with a single position. However, the tickets assigned to it are different. This can be seen in the beginning — after the
position reversal from Sell #2 to Buy #3.
What's next?
Next, we will implement tracking StopLimit orders activation and prepare the functionality to track modifying orders and positions.
All files of the current version of the library are attached below together with the test EA files for you to test and download.

Library for easy and quick development of MetaTrader programs (part VII): StopLimit order activation events, preparing the functionality for order and position modification events
In the previous articles, we started creating a large cross-platform library simplifying the development of programs for MetaTrader 5 and MetaTrader 4 platforms. In the sixth part, we trained the library to work with positions on netting accounts. Here we will implement tracking StopLimit orders activation and prepare the functionality to track order and position modification events.
Applying OLAP in trading (part 2): Visualizing the interactive multidimensional data analysis results
In this article, we consider the creation of an interactive graphical interface for an MQL program, which is designed for the processing of account history and trading reports using OLAP techniques. To obtain a visual result, we will use maximizable and scalable windows, an adaptive layout of rubber controls and a new control for displaying diagrams. To provide the visualization functionality, we will implement a GUI with the selection of variables along coordinate axes, as well as with the selection of aggregate functions, diagram types and sorting options.
Evaluating the ability of Fractal index and Hurst exponent to predict financial time series
Studies related to search for the fractal behavior of financial data suggest that behind the seemingly chaotic behavior of economic time series there are hidden stable mechanisms of participants' collective behavior. These mechanisms can lead to the emergence of price dynamics on the exchange, which can define and describe specific properties of price series. When applied to trading, one could benefit from the indicators which can efficiently and reliably estimate the fractal parameters in the scale and time frame, which are relevant in practice.
Applying OLAP in trading (part 1): Online analysis of multidimensional data
The article describes how to create a framework for the online analysis of multidimensional data (OLAP), as well as how to implement this in MQL and to apply such analysis in the MetaTrader environment using the example of trading account history processing.
