    Hi all, this is a question for IB users. When you make an order to buy/sell SPX options, do you select SMART as your preferred router? Or do you rout directly to CBOE instead? I understand that SMART probably fills faster since it scans different ECNS and ATSs but does it fill at a better price and incur less commissions. I would like to have your thoughts on this. Thanks!:)

    CBOE has a monopoly on SPX options and therefore using SMART shouldn't make any difference since there is nowhere else to find a better price.

    I've always used SMART for all of my option trading but I've observed that all of my SPX trades clear through CBOE. Thanks to ACS I now know why!
