hi

my code is flowwing...

double d;
//+----------------------------------
int OnInit()
  {
//---
   d=iRSI(Symbol(),Period(),14,PRICE_CLOSE);
   Comment(d);
//---
   return(INIT_SUCCEEDED);
  }
/* result= 10.0 */

in the code above, iRSI function returned 10, but rsi indicator on indicator window is 56.8!!!

in fact; in the code above, every time, iRSI function returned 10, so always d=10.0

what is worng?

Perhaps you should read the manual, especially the examples. They all (including iCustom) return a handle (an int.) You get that in OnInit. In OnTick (after the indicator has updated its buffers,) you use the handle, shift and count to get the data.
