Supertrend of a specific bar using iCustom

Hi homi,

Let�s assume we want to return the value of the indicator �Supertrend� of a specific bar using iCustom. 

If we want to get the returned value of the Supertrend first line:
We can write this price of code inside start() function:

Code:

double val=iCustom(NULL, 0, "SuperTrend",0,0,pos);

Here val will hold the returned value of Supertrend indicator(first line).

If you want the returned value of the second line, we can write:

Code:

double val=iCustom(NULL, 0, "SuperTrend",0,1,pos);

This is a program which will use Supertrend indicator using iCustom:

Code:

int start()
  {
   int    counted_bars=IndicatorCounted();
 
//---- check for possible errors
   if (counted_bars<0) return(-1);
//---- last counted bar will be recounted
   if (counted_bars>0) counted_bars--;
   
   int pos=Bars-counted_bars;
   
     
 
   while(pos>=0)
     {
         ExtMapBuffer1[pos] = iCustom(NULL, 0, "SuperTrend",0,0,pos);
         ExtMapBuffer2[pos] = iCustom(NULL, 0, "SuperTrend",0,1,pos);

         pos--;
     }

   return(0);
  }

==================================================
Use something like this in your EA:

Buff0=iCustom(NULL,0,"Indicator Name",0,0); //Top color of indicator
Buff0=iCustom(NULL,0,"Indicator Name",0,1); //1-Back

Buff1=iCustom(NULL,0,"Indicator Name",1,0); //Next to top color of indicator
Buff1=iCustom(NULL,0,"Indicator Name",1,1); //1-Back

Modify the variables in the indicator itself, and recompile the indicator which will update the buffers and the indicator on the graph!
===================================================

iCustom(NULL,0,"SuperTrend",10,3,0,1) //buffer 0 ie uptrend
 
iCustom(NULL,0,"SuperTrend",10,3,1,1) //buffer 1 ie downtrend
