How to add 1 indicator to my ea

Hi, how can i add 1 indicator to my ea as a criteria?

You must use the iCustom(...) function to call the indicator.

Thanks FerruFux for answering but now i am on my mt4 where can i find icustom?
And how to put the indicator in the EA (paste and copy in source perhaps?) and how to set parameters when indicator crosses x level to only buy or sell then.

Thanks!

iCustom is a programming function to be used in the EA code. This function calls the indicator buffers (eg. arrows, lines) ... Once this coded, you can use the result to check if conditions agree according to your strategy.

BTW, that's not a copy and paste job ... You must have some basics understanding of the MQL programming language.

Thanks again
