    Is IB designed to just feed liquidity to Timber Hill?

    IB indeed does not implement all the order types the various ECNs offer. Instead we opt for putting as much logic into 'Smart' as we can for the following reasons: - in the constantly changing fragmented market place we want the trader to focus on making trading decisions instead of worrying...

    This sounds weird. Please send the order particulars (time, size, price, series) to help@interactivebrokers.com and put mg101 into the subject line. That way I'll get the email and we will check it out. IB does not hold orders. Thank you.

    TWS unstable since Thurs 6/19

    This is not correct. We are not making the platform available to IB customers as is. Rather, we are making a lot of good functionality available in the FT platform part of IB-TWS. The next release 886, scheduled for beta this week or next, contains some FT functionality.

    IB vs Thinkorswim RE: price improvement

    The point of BOX is not that the auction is not triggered by non-marketable orders. Rather, the broker has to first (off line) find a party that will provide at least 1 penny worth of improvement. Without that the auction will not start. I don't agree with scanning for liquidity in options...

    IB vs Thinkorswim RE: price improvement

    Thank you for your post. To my knowledge there is no such thing as hidden orders in options. Our stock smart does scan for hidden liquidity in some of the pools we have access to. I am looking into what we could improve.
