How create bar or candle in subwindow ??

New comment
 

Hello ;

I would like to represent at the first time the Macd (with 2lines ) in Bar or like a candle just with body : so if line1 > line2 I draw it in Blue and of course in opposite in red :

so my problem is how to procede ?? the discussion about it is here where he would to draw Haikin Ashi in subwindow :

https://www.mql5.com/en/forum/120003

so I begin we simple code basing on MAcd (I suppose that I have Macd as an indicator and call it by the function iCustom 

#property indicator_separate_window
//#property indicator_chart_window
#property indicator_buffers 2
//#property indicator_color1 C'None'
//#property indicator_color2 DarkKhaki
//--- buffers
double ExtMapBuffer1[];
double ExtMapBuffer2[];
//+------------------------------------------------------------------+
//| Custom indicator initialization function                         |

int init()
  {
//---- indicators
  // SetIndexStyle(0,DRAW_LINE);
   SetIndexBuffer(0,ExtMapBuffer1);
  // SetIndexStyle(1,DRAW_LINE);
   SetIndexBuffer(1,ExtMapBuffer2);
//----
   return(0);
  }

  {

   return(0);
  }
//+------------------------------------------------------------------+
//| Custom indicator iteration function                              |
//+------------------------------------------------------------------+
int start()
  {
   int    counted_bars=IndicatorCounted();
   int limit ;
   string nomligne;
   bool normal ;
//----

  if(counted_bars>0) counted_bars--;
      limit=Bars-counted_bars;
  
    //-- first moving average in the first buffer 
       for(int i=0; i<limit; i++)
    {
    
           // iCustom(NULL,0,"Hausseforce2",65,13,0,i);
           ExtMapBuffer1[i]=iCustom(NULL,0,"MACD",12,26,9,0,i);
           ExtMapBuffer2[i]=iCustom(NULL,0,"MACD",12,26,9,1,i);
           
           // ObjectCreate("ligne1label", OBJ_TEXT, 0, Time[0], ObjectGet("ligne1", OBJPROP_PRICE1) );
           
              nomligne = StringConcatenate("ligne",i);
              
            //  normal = ObjectCreate("ligne1label", OBJ_TEXT, 0, Time[0], ObjectGet("ligne1", OBJPROP_PRICE1) );
              
              normal = ObjectCreate(nomligne,OBJ_TREND,1,Time[i],ExtMapBuffer1[i],Time[i],ExtMapBuffer2[i]); 
              
               ObjectSet(nomligne,OBJPROP_WIDTH,3);
           
    }
           
   
//----
   return(0);
  }
//+------------------------------------------------------------------+

I don't know if it's necessary to declare the 2 buffers ( ExtMapBuffer1, ExtMapBuffer2) like that :

my other problem is the function Objectcreate . so I think i the objectcreate function the time of the 2 lines is the same but not their value !!

ObjectCreate(nomligne,OBJ_TREND,1,Time[i],ExtMapBuffer1[i],Time[i],ExtMapBuffer2[i]);

the macd is like this :

and the result of this code is :


so do you have an idea ?

thanks

You don't use a line for the Buffer drawing style you use a Histogram ( DRAW_HISTOGRAM https://docs.mql4.com/constants/drawstyles ), and you have to use 2 buffers, one for the start of the bar one for the end of the bar.
 

Hello;

do you think that I must use histogram cause here I make : // SetIndexStyle(0,DRAW_LINE); as a comment

int init()

  {
//---- indicators
  // SetIndexStyle(0,DRAW_LINE);
   SetIndexBuffer(0,ExtMapBuffer1);
  // SetIndexStyle(1,DRAW_LINE);
   SetIndexBuffer(1,ExtMapBuffer2);
//----
   return(0); 

}

so do you think that we must use SetIndexStyle(0,DRAW_HISTOGRAM); even if we draw an object ?? with ObjectCreate(nomligne,OBJ_TREND,

 
You can draw thousands of Trendlines if you wish, to represent bars, in my opinion it is more efficient to use an Indicator buffer to do this . . and yes, use Histograms. Even if you use TLs you still need 2 buffers, one for start one for end.
 

I try to change the code as you preconize :

#property indicator_separate_window
//#property indicator_chart_window
#property indicator_buffers 2
#property indicator_color1 Blue
#property indicator_color2 DarkKhaki
//--- buffers
double ExtMapBuffer1[];
double ExtMapBuffer2[];
//+------------------------------------------------------------------+
//| Custom indicator initialization function                         |
//+------------------------------------------------------------------+
int init()
  {
//---- indicators
   SetIndexStyle(0,DRAW_HISTOGRAM);
   SetIndexBuffer(0,ExtMapBuffer1);
   SetIndexStyle(1,DRAW_HISTOGRAM);
   SetIndexBuffer(1,ExtMapBuffer2);
//----
   return(0);
  }
//+------------------------------------------------------------------+

int deinit()
  {
//----
   
//----
   return(0);
  }
//+------------------------------------------------------------------+
//| Custom indicator iteration function                              |
//+------------------------------------------------------------------+
int start()
  {
   int    counted_bars=IndicatorCounted();
   int limit ;
   string nomligne;
   bool normal ;
//----

  if(counted_bars>0) counted_bars--;
      limit=Bars-counted_bars;
  
    //-- first moving average in the first buffer 
       for(int i=0; i<limit; i++)
    {
    
           // iCustom(NULL,0,"Hausseforce2",65,13,0,i);
           
           if(iCustom(NULL,0,"MACD",12,26,9,0,i)>=iCustom(NULL,0,"MACD",12,26,9,1,i))
           {
              ExtMapBuffer1[i]= iCustom(NULL,0,"MACD",12,26,9,0,i)- iCustom(NULL,0,"MACD",12,26,9,1,i);
           }
           else{
           
              ExtMapBuffer2[i]=iCustom(NULL,0,"MACD",12,26,9,0,i)- iCustom(NULL,0,"MACD",12,26,9,1,i);
           
           }


  }

return 0;

}

but he draws it like in the zero line like an histogram Macd !!

but me I would like to represent the MAcd like the first indicator (with 2 lines) but instead of 2 lines It shows me a bar or like a body candle !! and when if the 2 lines crosses over it's color is blue if not we draw it red

something like that : (the first image on the right where we present the indicator by candle

I think the problem with Histogram is it 'is drawed on horizontal line (0)

I would like to create something like that but here it is in the principal window and basing on Close and open (here is just : the body of candle ) .

and I would do the same for Macd where there are 2 lines

 

Your else in your code means you have a value for buffer1 OR buffer2 . . you have to have 2 values for each bar . . . START and STOP . . .

if(iCustom(NULL,0,"MACD",12,26,9,0,i)>=iCustom(NULL,0,"MACD",12,26,9,1,i))
           {
              ExtMapBuffer1[i]= iCustom(NULL,0,"MACD",12,26,9,0,i)- iCustom(NULL,0,"MACD",12,26,9,1,i);
           }
           else{
           
              ExtMapBuffer2[i]=iCustom(NULL,0,"MACD",12,26,9,0,i)- iCustom(NULL,0,"MACD",12,26,9,1,i);
           
           }

. . . otherwise the bar runs from 0 to buffer_value.

Get rid of the else and if

ExtMapBuffer1[i]= iCustom(NULL,0,"MACD",12,26,9,0,i)- iCustom(NULL,0,"MACD",12,26,9,1,i);

ExtMapBuffer2[i]=iCustom(NULL,0,"MACD",12,26,9,0,i)- iCustom(NULL,0,"MACD",12,26,9,1,i);
 

hi,

with code :

int start()
  {
   int    counted_bars=IndicatorCounted();
   int limit ;
   string nomligne;
   bool normal ;
//----

  if(counted_bars>0) counted_bars--;
      limit=Bars-counted_bars;
  
    //-- first moving average in the first buffer 
       for(int i=0; i<limit; i++)
    {
    
    ExtMapBuffer1[i]= iCustom(NULL,0,"MACD",12,26,9,0,i)- iCustom(NULL,0,"MACD",12,26,9,1,i);

     ExtMapBuffer2[i]=iCustom(NULL,0,"MACD",12,26,9,0,i)- iCustom(NULL,0,"MACD",12,26,9,1,i);

  }
           
   
//----
   return(0);
  }
//+------------------------------------------------------------------+

as you can see it represents just one buffer I suppose the blue is absent !! and hre the problem is the histogram draw under and above the horizontal line 0

 

These calculations are the same . . . 

ExtMapBuffer1[i]=   iCustom(NULL,0,"MACD",12,26,9,0,i)- iCustom(NULL,0,"MACD",12,26,9,1,i);

ExtMapBuffer2[i]=   iCustom(NULL,0,"MACD",12,26,9,0,i)- iCustom(NULL,0,"MACD",12,26,9,1,i);

. . . doesn't seem correct to me.

 

something like this?
