If someone is getting lower than $0.55/side please feel free to post it here.
If you're doing medium to heavy volume then you have a choice of either TransAct or Advantage Futures. A lot of professionals refer to Advantage as the best clearing firm that nobody has ever heard of. Awesome financials. They're clearing members of 4 different exchanges, claim to have more floor badges issued by they CBOT and CME than any other exchange member, and they always show up somewhere between 18 and 30 on all the FCM capitalization reports. You have to purchase a monthly X_TRADER license at a pretty hefty price, but if you're doing that kind of volume then you really could care less.
Hope this helps. If anyone has any better recommendations I would love to hear them.
