Hello, I'm trying to figure out if / how you can access calendar spreads real -time datas through IB API. I've tried enter it as a BAG type in excel but I can't figure out how to define the legs... I also tried to enter it as it is displayed in TWS ( Calendar Spread: -(1) MAR 08 + (1)MAY 08 ) but it doesn't work either. Does someone know how to get those datas in excel? Thanks for your help.
