Hi
excuse me!!
This problem(4109) is made for me!!!iwent to tools / options but there was no any tab with name of expert advisord .
Do you know the difference between MT4-Terminal and MT4-IDE ?
Often the "autotrading" is simply not set / switched off.

I'm kinda' new to using Scripts, and am running into a problem.
Using the standard (or any other) scripts on my InterbankFX demo account works fine, but I recently set up a live acount and whenever I try to execute a script I get an error message in the Expert Log that gives number 4109 - which I lookedup on the MQL4 website and it means, "Trade is not allowed".
Can anyone tell me what the problem is and how to fix it?
Thanks so much.
Mike
