Hello!

I'm trying to do an CCI indicator but show the error array out of range.

Follow my code and please help me!!

You have inserted the code correctly - thanks for that. Please (for the future) do one more additional action: attach (using the button ) Your code. Why you need to do this: it's so easy to check - I click on the attached file and the browser downloads this file right away. All I have to do is click on the downloaded file and the file will open in MetaEditor.

Corrected code - you need to be more careful with indexes.

***
   if(!FillArrayFromBuffer(BufferCCI,handle_iCCI,values_to_copy))
      return(0);
//--- main loop
   int limit=prev_calculated-1;
   if(prev_calculated==0)
      limit=1;
   for(int i=limit; i<rates_total; i++)
     {
      OpenBuffer[i]=open[i];
      HighBuffer[i]=high[i];
      LowBuffer[i]=low[i];
      CloseBuffer[i]=close[i];
      CandlesColors[i]=0.0;
      //---
      if(BufferCCI[i-1]<0.0 && BufferCCI[i]>=0.0)
        {
         CandlesColors[i]=1.0;
        }
      if(BufferCCI[i-1]>0.0 && BufferCCI[i]<=0.0)
        {
         CandlesColors[i]=0.0;
        }
      if(BufferCCI[i]>=0.0)
        {
         CandlesColors[i]=1.0;
        }
      else
        {
         CandlesColors[i]=0.0;
        }
     }
//--- memorize the number of values in the Commodity Channel Index indicator
   bars_calculated=calculated;
//--- return the prev_calculated value for the next call
   return(rates_total);
  }

I added the CCI indicator to the chart:

Sorry about it, it's my first time to do here...

Ok, I'll see where I write indexes and I'll rewrite

Thank you!
