Super Display Book
The super display book is the electronic order routing and execution system that bypasses the floor broker and sends the order right to the specialist / DMM for execution. If the order can be immediately executed, the system will send an electronic confirmation of the execution to the submitting broker dealer.
SecuritiesCE Explains Super Display Book
Most customer orders will never be handled by a floor broker. Floor brokers usually only handle the large complex institutional orders. Customer orders will be electronically routed directly to the trading post for execution via the super display book. All listed securities are eligible to be traded over the super display book system. All pre opening orders that can be matched up are automatically paired off by the system and executed at the opening price. Any pre opening orders that cannot be paired off are routed to the trading post for inclusion on the display book.
