Basic question on iCustom() and iMa()

New comment
 
Hello everyone,

I'm a developer, but I'm new to MQL4, and I'd like to understand a couple of basic stuff. I'm creating an EA that calls a couple of prepackaged indicators such as MA, RSI, etc, and a custom indicator. The question:

Do I need to add those indicators to the chart in order to get a return after my iCustom call (or iMa, iRsi for that matter) or is it enough to have them in the Indicators folder, and they're queried in run-time? 

Thanks a lot in advance.

 
You just need to have them in your indicator folder. No need to have them on the chart.
 
I will give you some time to read this, then I will move this to the MQL4 & Metatrader 4 sub-forum

Great news. Thanks a lot, Keith!
