[Nap$ter]

So habe mich mal dran gemacht und versucht den Befehl in einen Indikator einzubauen. Leider funktioniert es nicht. Vermutlich irgendwo ein Fehler. Die "Test.exe" Datei ist im File Ordner des MT4's. Hab noch wenig Erfahrung mit dem Programieren von MQL.
Auszug aus dem Indikator:

Leider wird beim Alarm die "Test.exe" nicht geöffnet...
Indikator im Anhang. Wäre cool von euch wenn sich jemand diesen mal kurz anschaut und die Fehler beseitigt.
