Hello To All,

What I have here is a Simple Indicator that calls iCCI and when I put that on a Chart it shows the same values each bar as the MT default CCI indicator.

When I call iCCI from an EA and print the values to the Journal every bar has a different value form the Indicator except first bar.

Here is the Simple Indicator

int init()

int start()
{
   int i = 0;
   
   i = Bars-Length-1;
   while ( i > 0 )
   {
      ExtMapBuffer1[i] = iCCI(NULL,0,Length,PRICE_TYPICAL,i);   
      i--;
   }
   return(0);
}
//+------------------------------------------------------------------+



And here is the simple EA that is calling iCCI

  {
   double Temp1 = 0.0;
   
   Temp1 = iCCI(NULL,0,Length,PRICE_TYPICAL,0);
   Print(Temp1);
   return(0);
  }

If I understand your problem correctly, you are monitoring current bar "0" in both Indicator and Expert Adviser.
In that case the loop while(i>0) will never produce i=0;
So you should modify while(i>-1) to get i=0 same as i=0 in the Expert Adviser.
I would put i into the Print statement because I believe that there will be i=1, i=0, in the indicator and i=0 in the expert only.

Hello Sub,

Thanks for taking the time to respond to my post. I have read what you have posted and I have looked at the values using the 'while(i>-1)' suggestion.

My Problems all stem from not calling CCI on the completion of each bar I was calling it on each tick.

Thank you

No. Some old forum topics were imported here.
