Pending Order Button Expert

Neuer Kommentar
 

Hallo zusammen!

Habe diesen Code von einem Youtuber (Jim Dandy 1958). Ursprünglich war es ein kleines Programm mit zwei Buttons auf dem Chart, einem für Buy und einem für Sell Order: Man drückt den Knopf und sofort wird mit Hilfe der externen Variablen eine komplette Order inklusive SL und TP erstellt. Soweit hat das auch funktioniert.

Jetzt habe ich versucht, das Ganze so zu verändern, dass ich vier Buttons habe, mit denen ich BuyLimit, SellLimit, BuyStop und SellStop erzeugen kann, wieder mit Hilfe der externen Variablen. Nur leider klappt das nicht. Meta Trader sagt "invalid ticket", Fehlercode 4051, d.h. ungültiger Funktionsparameter. Ich schätze es liegt daran, dass ich das Argument im Chart Event und in der PlaceOrder Funktion gleich benannt habe, bin mir jedoch nicht sicher, wie ich jetzt verfahren soll. Bin dankbar für jede Hilfe.

Hier der Code:
