Can I have help on How to call iCustom indicator from my EA mql4. I have been trying to tell my EA to send orders when the price riches UniqueprcLineup or UniqueprcLinedown.

Why did you post your MT4 question in the MT5 General section instead of the MQL4 section, (bottom of the Root page)?

Next time, post in the correct place. The moderators will likely move this thread there soon.
Please edit your (original) post and use the CODE button (Alt-S)! (For large amounts of code, attach it.)

ICustom reads buffers; your indicator doesn't have any.

Multiple moving average cross Please help. While I icustom EA errors
