I complained with CME about that they cash in exchange fee twice. I will try once again with CME and if result not positive will file a complaint with CFTC. My view is that exchange must keep track of payments that they receive and should not charge twice just to fill their pockets faster. Will do the same with CBOT. You pay 30 $ to IB and same amount to your data vendor. They simply cash in twice !Yet I am charged for quotes twice. Once with IB and again with RT. Why should clients pay twice for the same thing?!?
