using the standard CCI on mt5 what do i get this error

[Amos Tsopotsa]

i have noticed that my first version for this code was working well, now it calls it as if its a custom indicator that i not on mql5 ,could this be a conflict that i already have a cci custom indicator, while i using a standard, I plugged the EA to trade on one pair and it was allowed and still working very well, on the other pairs its rejecting the EA to work Attached is the final code ,it is still in development will add filters money management and break even etc.Another issue i have noticed is that it disappears on the chart

[Carl Schreiber]

If you have coded you own cci don't name it cci but e.g. CCImy.mq5 - with this (simple) way you would not ran into a conflict of names.

And if the original is changed by MQ your version wouldn't be overwritten!

So always work on renamed copies!
