Just taking a look at this contract for the first time thanks to this interesting thread. Does anyone use IB to trade the Eurodollar? When I pull up say GE Sep 05 on TWS, I don't see any bid/ask data. I'm used to the minis, so it just doesn't look right to me. Do you use time and sales, depth of market or volume in your trading? Also, do you trade pit hours only?
