I am using Tradestation connected to NT. I have written my code using the DLL (not email).
I have been trading emini SP's from my laptop successfully for the last week, using ticker symbol @ES.D.
Today I decided to switch to my more powerfull desktop and now when it trades, it trades the Sep's instead of the correct Jun's.
I looked in the instrument manager, and I cannot find an option to tell it which expiry to use if using a continuous contract chart from TS.
Any ideas?>
