Help me! iCustom function

[nhatkhanguyen92]

I have 1 EA that uses iCustom function to get Fisher indicator data

When back test there are too many windows of the Fisher indicator.

Please help me fix this

Thanks for reading

int OnInit()
  {
   ArraySetAsSeries(priceInfo, true);
   ArraySetAsSeries(fisherArray, true);
   

   return(INIT_SUCCEEDED);
  }

void OnTick()
  {
   nameChart = _Symbol+subName;
   copy = CopyRates( nameChart, _Period, 0 , 10, priceInfo);
   
   if(priceInfo[0].tick_volume == 1){
      if(priceInfo[0].time > (candlesTime + 2*PeriodSeconds() )){
         int _data = iCustom(nameChart, _Period, "Scalping\\Fisher", 10,0,0);
         CopyBuffer(_data, 0, 0, 10, fisherArray);
         fTrend = fisherArray[0];
         ArrayFree( fisherArray );
         order = openOrder(nameChart, _Period, priceInfo, fTrend, nameBot );
        
        }
   }

Try creating your indicator handle from the OnInit() instead of from the OnTick(). That way it be created once instead of at every tick!

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.
