Hi Guys,
I need your expert brains for a moment. Is there a way to assign a different audio file to a custom indicator? I have an EA running and a moving average cross over with audio alert all running at the same time. They both have the same audio alert. So, if I can change one to a different sound

, it will make it much clearer when I should run back into the room. Does that make sense?
I asked a MT4 friend about this in a chat room, and he said that MT4 uses the same audio file for all alerts. Is this true?
Thanks!
