I've got an IB data feed and am trading futures, I want to be able to run strategies for calendar spreads.. From what I understand I will have to check the two symbols in my watchlist for example
CL 042009, CL052009
and in my code create a UserSeries within code and do my stuff against that.. I've been doing this with product spreads and it works fine.
However, when I select the same product I get the following exception
An entry with the same key already exists.
From what I understand the unique key in this case is JUST the symbol name...
Is there any way to solve this problem..???
Thanx in advance
