Use iCustom() call
 
Mladen Rakic:
Use iCustom() call
I tried, but the thing is that i dont understand indicators. i knew that iCustom is used but i couldnt figure out how can i use it.

Follow that link and it is explained there how you use iCustom()

  1. When you post code please use the SRC button! Please edit your post.
              General rules and best pratices of the Forum. - General - MQL5 programming forum

  2. Just get the value(s) of the indicator(s) into the EA and do what you want with it.
    You should encapsulate your iCustom calls to make your code self-documenting.
