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.
- 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 - 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.
Detailed explanation of iCustom - MQL4 and MetaTrader 4 - MQL4 programming forum
