Price Improvement Auction

Trading Term

For option orders routed to the Boston Options Exchange (BOX) you may elect to participate in the BOX’s price improvement auction in pennies. All BOX-directed price improvement orders are immediately sent from Interactive Brokers to the BOX order book, and when the terms allow, IB will evaluate it for inclusion in a price improvement auction based on price and volume priority.
