What is the symbol/s on IB for ATM eurodollar futures puts in further out months like Mar, June, Sept, Dec of 2010 and 2011. I'm wanting to match option prices from barcharts option data in there futures quotes. I'm looking for liquidity. IB's Option Trader platform has a MILLION different ways to go before you get to the Dec 2010 options or any other month. I get confused right from the beginning. Whats the correnct starting symbol and which trading class do I use???? I just want to match barchart. Please help me with this maze.
