does anyone know how the CCI on the chart is calculated?

look at the attached pictures

on chart - 14/Nov 10:00 CCI is -208.7495

in my EA - 14/Nov 10:00 iCCI returns -149.5238

in my EA, I'm using the: iCCI(NULL,0,CciPeriod,PRICE_CLOSE,0) CciPeriod=14

I also tryed using PRICE_TYPICAL and PRICE_OPEN, but yet failed to get the CCI value that I see in the chart

please help...

No, other bars are wrong as well.

the code is below. maybe you can help point to the issue

  2. cci.mq4 has


thanks for comments

I edited the code as you metioned in #1

in #2, I'm not sure I got your suggestion.

even before the iMA that I'm using, simple iCCI in my EA (look for the print statement) shows different value that CCI indicator.

I attached a picture that shows the different values.

CheckForRule();

}

double CCI_0 =iCCI(NULL,0,CciPeriod,PRICE_CLOSE,0);
Comment("CCI_0  = ",CCI_0);


return(0);

}

put the green lines inside your code

Check this and you will see the value of CCI at bar 0 every tick....

So why is it different ????

#2 was not a suggestion. You asked "dorkor22: does anyone know how the CCI on the chart is calculated?"Answer using PRICE_TYPICAL
