Perhaps you should read the manual. You don't call indicators. You read the buffers with iCustom.

We're not going to code it for you (although it could happen if you are lucky or the issue is interesting).

Hi!

1) You create handle of indicator by iCustom(). It is better to do in in OnInit().

2) You use CopyBuffer() for getting values from created handle.

You must NOT mix OnTick() and OnCalculate(), one is only for EAs one only for indicators!

You should study(!):

Quickstart for newbies: https://www.mql5.com/en/articles/496
and: https://www.mql5.com/en/articles/100
cookbook: https://www.mql5.com/en/search#!keyword=cookbook

Bear in mind there's virtually nothing that hasn't already been programmed for MT4/MT5 and is ready for you - so searching gives better results than AI or ChatGPT!
