I would appreciate some input from traders that trade the CME Eurodollar futures. My website is www.chart-ex.com and I want to add the Eurodollar contract. My questions is what month/months would be the best to add? How does the lead month rotate? Our present default is to pick up the lead month is according to highest open interest. I noticed the OI in the Eurodollar contracts is about equal for the Dec06, Mar07, Sep07 and Dec07 presently. Thanks for your time and input.
