I'm trying to get in some TASR options for more than 1 hour now. I use smart order routing tool from IB. I try to buy MAY 90 Put. Best Bid I see on IB is 13.20. I'm standing in there with 13.40 at the moment. My bid has always been better than 0.20 than the best bid I see for more than 1 hour now. Why does ISE not show my bid?? Is this legal? Smart order routing tool from IB does definitely not show the best bid!! I'm also wondering why IB does route all my option orders in TASR to ISE? Have done quite a lot TASR options in the last couple of days. Something stinks here, IMHO.
