Quote from Options12:
Thanks for the post, IBsoft.
Does your last paragraph mean that the "Highest Rebate" preference hajimow has described does not apply to the liquidity taker rebate at BOX?
That is, if CBOE and BOX both offer the NBBO and a user has set the preference to "Highest Rebate," might the IB system route the order to CBOE instead of BOX if Timber Hill designates CBOE as the venue where IB will receive the most payment for the order?
(from the IB Payment-For-Order-Flow Disclosure / most recent 606 report)
If multiple exchanges are quoting at the NBBO for an option order and IB has discretion as to where to send the order or a portion of it, IB generally will âbreak the tieâ by sending the order to an exchange where it will receive the most payment for the order, or to an exchange designated by the firm from whom IB will receive the most payment (typically IBâs affiliate Timber Hill LLC â see below).
As I explained, the smart routing preferences, such as "Highest Rebate", apply to liquidity providing (not taking) orders.
The smart router optimizes the routes to benefit the customer. It will not route a marketable order to CBOE, when BOX is at NBBO. Timber Hill preference will only be considered when all else is equal for the customer, e.g. the order is only marketable at AMEX and CBOE.
The language you refer to predates the maker/taker exchanges.
