Help me to use indicator inside EA as a function

New comment
 

Hi everybody,

I'm wondering if there is a way to convert DT oscillator (attached) to a function, such as this:

double calculateDT(int timeframe, int PeriodRSI, int PeriodStoch,int PeriodSK, int PeriodSD,int MAMode,int line,int shift)

{

//

//here is the codes

//

}


here is the main "start" section of indicator:

int start()
{
   int i,limit;
   int counted_bars = IndicatorCounted();

   if(counted_bars < 0) return(-1);
   if(counted_bars > 0) counted_bars--;
             limit=Bars-counted_bars;

 
   if (returnBars) { SK[0] = limit; return(0); }
   if (timeFrame != Period())
   {
      limit = MathMax(limit,MathMin(Bars,iCustom(NULL,timeFrame,IndicatorFileName,"getBarsCount",0,0)*timeFrame/Period()));
         
     
      for(i=0; i<limit; i++)
      {
         int y = iBarShift(NULL,timeFrame,Time[i]);
            SK[i] = iCustom(NULL,timeFrame,IndicatorFileName,"",PeriodRSI,PeriodStoch,PeriodSK,PeriodSD,MAMode,0,y);
            SD[i] = iCustom(NULL,timeFrame,IndicatorFileName,"",PeriodRSI,PeriodStoch,PeriodSK,PeriodSD,MAMode,1,y);
      }               
      return(0);         
   }

             
   for(i=limit-1; i>=0; i--)
   {
      RSI[i] = iRSI(NULL,0,PeriodRSI,PRICE_CLOSE,i);
      double LLV = RSI[ArrayMinimum(RSI,PeriodStoch,i)];
      double HHV = RSI[ArrayMaximum(RSI,PeriodStoch,i)];
      if ((HHV-LLV)!=0)
            StoRSI[i] = 100.0*((RSI[i] - LLV)/(HHV - LLV));
      else  StoRSI[i] = 0;
   }   
   for(i=limit; i>=0; i--) SK[i]=iMAOnArray(StoRSI,0,PeriodSK,0,MAMode,i);
   for(i=limit; i>=0; i--) SD[i]=iMAOnArray(    SK,0,PeriodSD,0,MAMode,i);
   return(0);
}

//

I almost did it and works on current time frame, but it's not working on different timeframes. Would somebody please help me???

That is exactly what you should write, an encapsulated iCustom call to make your code self-documenting.

Thanks whroeder1 for your reply, but I don't want to use iCustom because it's very slow and my EA calls the function several times in each tick, so EA optimization will be almost impossible. I want to import the calculation of indicator inside my own function...
