Your title says MT4, but your post says MT5?

If it's MT5, you don't need the first line of code...

TesterWithdrawal() function does not work in Mql4 (can compile, but when run will give error 4014 - ERR_UNKNOWN_COMMAND).

I can see why you have your first line, but unless you're prepared to implement your own version of this function, it's useless having that line there.

You'll see error when u include GetLastError() in your code, after you call TesterWithdrawal().

What I know is that MT4 does not support that. Solutions some people tried are (1) using a 3rd party solution (e.g. Tick Data Suite), or (2) do your own code-based moderation of account balance (accounting for commissions) to influence the subsequent lot sizes your EA trades.
