currently only trading US ags/energies, but have decided to expand the desk and branch into several other products. What is best US FCM for clearing Eurex and ASX trades? taking into consideration everything, but mostly for total product access (current FCM does not support Spanish or Italian bond futures on Eurex) and no haircut on currency conversion, as well as familiarity with inter-product spreads and execution (I execute via CQG, but just in case)
