I would like my mql5 code to run a key , like for example "A" anytime a specific action occurs. Is it possible ? Anybody knowing how to do it ? Example : microsoft word is launched and the expert runs in background. any time the action occurs , a "A"
I've seen some other languages like mql5 , but they were really basic and did not permitted the study of the order book ; like , they didn't had equivalent for "a=book.volume" for example , just to give an idea. Is there any other trading
