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:

   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--;
     }
