I'm trying to understand how I can write a 3rd party extension for MT4...
It appears that one way would be to write an EA that connects to external libraries, but I'm not finding many resources on how to implement this.
Let's say I had an application running that takes in signal data from the EA, then makes a trade decision on its own and sends the order back to the EA for execution within MT4... how can I pass such messages back and forth like that?
YES, I know I could just do it all in MQL4 and run it right within the EA, that's not quite what I'm aiming to do and some of the stuff I want to achieve isn't easily done in MQL4 anyway...
Anyone have any experience with this sorta thing? Got a direction to point me in?
