Quick pointer on how this indicator rounds to 4 decimal places....

Hi

Here is the ATR indicator in mt4:

      for(i=1;i<=AtrPeriod;i++) AtrBuffer[Bars-i]=0.0;

   i=Bars-counted_bars-1;
   while(i>=0)
     {
      double high=High[i];
      double low =Low[i];
      if(i==Bars-1) TempBuffer[i]=high-low;
      else
        {
         double prevclose=Close[i+1];
         TempBuffer[i]=MathMax(high,prevclose)-MathMin(low,prevclose);
        }
      i--;
     }

   int limit=Bars-counted_bars;
   for(i=0; i<limit; i++){AtrBuffer[i]=iMAOnArray(TempBuffer,Bars,AtrPeriod,0,MODE_SMA,i);}

   }

It outputs to 4 decimal places, eg: 0.0023 can anyone show me were this is set in the above code?

Thanks

I don't understand your question. What should it be if not 0.0023?

Hi

The 0.0023 is jsut an example, it always displays 0.**** which is 4 digits after the decimal point, I was wondering how it does this as I need to change it to 0.*** 3 digits, if this is possible.

Thanks

can someone help me edit sar ohlc to use heiken ashi ohlc

Hi, I have an MTF indicator that uses sar, however I'd like the sar to calculate heiken ashi ohlc, and not the normal type

Can you tell me how I can do this, my mtf indicator calls to the sar indicator to calculate sar formula, I think it is calling to the internal indicator in mt4 that can not edit

you can skype or email if you can assist and like to talk about it

skype sty671

email sty671@gmail.com

I can also supply the original file that I'm trying to use heiken ashi ohlc for
