Trigger a Trailing Stop (Options)

[OffTheVWAP 0]

Good afternoon,

I am trying to figure out how to trigger a predefined order at a certain option price. Here is my example:

Say I have 10 contracts of AMD 75 Calls, and I bought them at $2.00 per contract.

I have this hotkey/script "CXL ALLSYMB;ROUTE=LIMIT;Price=Bid;Share=Pos*0.5;TIF=DAY+;SELL=Send;Price=Ask-AvgCost-0.02;TriggerOrder=RT:STOP STOPTYPE:TRAILING StopPrice:Price TrailPrice=Round2 ACT:SELL QTY:POS TIF:DAY+"

that I want to fire off automatically when the option price hits $2.50

I have not been able to figure out a way to do this. Any help would be greatly appreciated 

Thank you,

Joseph
