Linking EA to an Exe

Hai,

have an external application(VC++ exe) which decides when to fire orders.
--- Now I want to link my external application to the expert advisor.
How i can do this

It's easier to write a dll and link your EA to that, rather than messing with an external executable.

Can u please explain me how to do that. I am a C++ programmer & i am new to MQL4,2 days back only i started wrkng on MQL4.It will be helpful if u give more details

If you just search for "dll" on this site, you'll find plenty of breadcrumbs showing how to link MT4 to a dll.

Did you write the program you're trying to link to? If so, you should be able to restructure it so that it presents a function call interface and use the MSVC project wizard to create a dll instead of an application. Again, this subject matter is well-covered on the interwebs.
