IB rate is $0.85 on 1 contract Mirus is ES $.49; PLUS exchange fee for 1$? = so total is 1.49?? On IB site it says " Our pricing for futures in US markets includes our low broker commission plus exchange, regulatory and clearing fees. You are not charged a carrying fee for positions held overnight. 1" so why would anyone in the right mind ever join brokers like mirus or optimus??? am i missing something here?
