Order Behaviors

• Market orders are matched within BYX if BYX is currently the best bid/ask of the market (that is, "at the inside"). If not, the order is routed using BYX smart order routing logic. Any residual volume will not be routed to the next price level until all quotes at the current best bid offer are exhausted. BYX Market orders do not guarantee a fill and may reject, cancel, or expire prior to being completely filled. BYX will continue to route to the next price level until any of the following is true:
  • All residual volume is exhausted, at which point the order is completely filled.
  • All attainable liquidity at a specific price level is exhausted and the market data has not updated indicating a new NBBO, at which point the order will be rejected back to the user.
  • Attainable liquidity is exhausted within an extreme price constraint of $0.10 or 1% (whichever is greater) worse than the NBBO at the original time of the order, at which point the order will be rejected back to the user.
• Marketable limit orders are matched with BYX if BYX is currently the best bid/ask of the market (that is, "at the inside"). If not, the order is routed using BYX smart order routing logic. Order price may be improved. BYX caps the limit price of a marketable limit order to the NBBO at the time of order placement. Once all attainable liquidity within that capped limit price is exhausted, the order will be rejected back to the user.
• Non-marketable limit orders are posted to the BYX book. The best bid and offer in the BYX book will be displayed in the Market Depth window (under either the CINN or the ISEG market participant ID).
• Stop Market Orders are initially routed to our stop server until triggered. Once triggered, an order routed to BYX will behave as a Market order.
• Stop Limit Orders are initially routed to our stop server until triggered. Once triggered, an order routed to BYX will behave as a Limit order.
• An Immediate or Cancel (IOC) order is matched within the BYX book only if BYX is at the inside. Non-marketable orders are immediately rejected, partial fills will be accepted.
• A Fill or Kill (FOK) order is matched within the BYX book only if BYX is at the inside. Non-marketable orders are immediately rejected; partial fills will not be accepted.
• Unfilled orders and leaves set for Minute durations (such as 1,3,5 Minute) expire immediately after the designated number of minutes.
