Indicator's value is different from values pulled via iCustom() of the same indicator.

[suvroc]

I want to backtest one indicator named StableFX. But when I try to run the test "0" buffer of the StableFX indicator is -134, for example, but 0 buffer pulled with iCustom() is -65 on the same date. So the value showed by indicator and value pulled by iCustom is always different. I checked everything and , parameters are matched, buffer indexes to read from are correct, I am trying to detect crossover of the 0 and 1st buffers, but as I mentioned above values are not what indicator is showing in the window. I think I am missing something but can't seem to detect it. I have provided all the code that might be required. I Also attached screenshot with selected values to show what I mean. Please can someone point what I am doing wrong?

int OnInit()
  {
//---
   glTimeBarOpen = D'1971.01.01 00:00';

   atrHandle = iATR(_Symbol,PERIOD_CURRENT,atrPeriod);
   
   stableFxHandle = iCustom(_Symbol,PERIOD_CURRENT, "StableFx.ex5", inpKPeriod,inpDPeriod,inpSlowing,inpCCI,inpC1,inpC2,inpC3,inpP,inpMaPeriod,inpMaMethod,inpPeriod);// this indicator
   
   if(stableFxHandle == INVALID_HANDLE)
     {
         Print("FAILED TO INIT DIDI INDEX INDICATOR");
         return (INIT_FAILED);
     }
   
   if (atrHandle == INVALID_HANDLE) 
   {
      Print("FAILED TO INIT ATR INDICATOR");
      return (INIT_FAILED);
   }
   

   
//---
   return(INIT_SUCCEEDED);

here how I am getting signal :

entrySignal = detectCrossover(stableFxHandle, 0, 1, glTimeBarOpen);



string detectCrossover(int pHandle, int pSignalBuffer1, int pSignalBuffer2, const datetime time)
  {
   MqlDateTime dt;
   TimeToStruct(time,dt);
   double indicator1[];
   double indicator2[];
   CopyBuffer(pHandle,pSignalBuffer1,0,3,indicator1);
   CopyBuffer(pHandle,pSignalBuffer2,0,3,indicator2);
   ArraySetAsSeries(indicator1, true);
   ArraySetAsSeries(indicator2, true);
   if(indicator1[0] > indicator2[0] && (indicator1[1] <= indicator2[1]))// || (dt.day_of_week == 1 && indicator[1] > pCrossLine && indicator[2] <= pCrossLine )))
     {
      return  "LONG";

     }
   else
      if(indicator1[0] < indicator2[0] && (indicator1[1] >= indicator2[1])) // || (dt.day_of_week == 1 && indicator[1] < pCrossLine && indicator[2] >= pCrossLine)))
        {
         return  "SHORT";
        }
   return "NO TRADE - " + DoubleToString(indicator1[0]) + " | " + DoubleToString(indicator2[0])  + " | " + DoubleToString(dt.day_of_week) + " | " + DoubleToString(indicator1[1]) + " | " + DoubleToString(indicator2[1]);
  
  }

Correct return code.

Thank you for pointing out this error. I have already fixed it, but my issue still remains. I hoped that someone would help me find my mistake causing this behavior.

Since I don't see the rest of your code...

It might be related to this:

   ArraySetAsSeries(indicator1, true);
   ArraySetAsSeries(indicator2, true);

Try setting it to false and see if it matches then.

I have tried but there was no result. I have uploaded all the source code of the indicator and EA if you want to see the whole code.

Or set it to true, before filling the arrays.

 Tried it too, values stays the same. As far as I can deduce buffer 1 of the indicator and iCustom's buffer 1 are showing nearly the same values, difference, I think, is coming from the fact that I am reading values at 23.30 , 30 minutes before daily bar close. But buffer the difference between buffer 0 of the indicator and iCustom is just too big, nearly 2x difference.
