Calling optimizer from within EA-code (MT4)

[[Deleted]]

Hi,

 with the code

// Start Tester 
start = ShellExecuteA(0, "Open", "terminal.exe", FileOptim, PathTester, 3);

 I can call a second MT4 instance and start the tester with pre-defined optimization settings.

This principle is described in this article. I tried it and it works fine.

But!

How can I start the optimizer of the MT4 instance, where my EA is running? Means I don't want to start a second MT4 instance. 

Does anybody know the necessary command?

 

Thanks!

Why not? Optimization takes time. Do you really want to stop the current EA and wait for the optimization to complete?

No, the EA continues in parallel. I just check from the EA whether the report file is finished. Then I know, that optimization has finished and I take the parameter out of the report file.

And it's not just for optimizing the parameter of a specific EA from within the EA. I like the idea to have full control over the optimization itself.  So you could control from a script, indicator or EA the optimization of a strategy, do customized walk-forward tests, change optimization parameter depending on the result of a finished optization, create your own criterias for walk forward tests...
