good afternoon for everyone...

I dont kno nothing about MQL4 I learn but it's hard to entry in my mind.

I have two indicators and I want create a automate EA with simple idea I have two indicators. and the EA its simple when indicator "A" give me the buy signal the system put the order and when the indicator "B" give the selling signal the EA close the buy order and vice versa. But the problem is, I read and read and keeping don'tr understanding. the language. Somebody could help there is videos tutorials to create a EA. Or give me some universal recipe to made it.

the indicators mql4 code is:

use iCustom

here you have an Alphabetic Index of MQL4 Functions (600+)

very helpful
