Function to call some external executable

[Jin]

Hey Ross,

Does MQL5 has some function that can execute an external program (both synchronously or unsynchronously) ??

We could used it as a trigger to some external process, in a very simple way (we could call this function from OnTick() event handler).

It would help a lot the integration of Metratrader with something outside, without the use of C dll's, WCF, interops, and others tricks.

 

The signature of this function could be something like: 

void CallingExternProg(string fileName, bool synch); 

 

Thank you.

I have just figured out that would be better to have a signature like:

 void  CmdShell(string cmd, bool sync);

Example:

...

CmdSheel "..\myprog -param1 -param2", TRUE;

...

That would make all the EAs/indicators/scipts potential major security threats.
