Hi! I've read the excellent text:Secrets of MetaTrader 4 Client Terminal: Alerting System. This is very good. I have a question.I need to trigger .exe from an EA either for buy, sell, or else. It says we can trigger either a .bat .exe or .vbs instead of the .wav file from the events setup window.. My idea is to have a buy alert and a sell alert trigger different .exe files. Can the PlaySound command can also be used to trigger .exe file from within a .mq4 EA??? I hope my question is clear. Please NewDigital or Codeguru may you answer?
