i've now noticed this 4 are 5 times. i have an account with ib and another outfit. today yet again i tried to buy some options that were $6.20x$6.40 at $6.30. i used ib's smart order thats supposed to route to the best fill. well i became the bid. so i stuck the same order in at $6.30 with the other firm and got an instant fill at $6.30 which was showing as the bid because of my order at ib. this has happened at least 5 times. it means ib''s selling the order flow and not giving me the best price
