At IB option exchange fees are charged separately from IB commissions (unbundled pricing), and for Penny Pilot Issues both BOX and PSE charge substantial fees (45Â¢ resp. 50Â¢ p.contract) for marketable orders (those that remove liquidity) while giving a 25Â¢ rebate for non-marketable orders (add liquidity). Thatâs 70-75Â¢ difference per contract. So I submit a SmartRouted, non-marketable limit order that is working at an exchange, say at BOX, and after a while it is executed, not at BOX, but at PSE (with Smart orders you cannot control the execution venue). Rebate? Wham! Iâm charged the additional 50Â¢ PSE fee because, I assume, the order was never working at PSE, so it was never in their books until it was executed, so from PSE perspective it was a marketable order. Does anyone recognize this issue?
