Opening Process

The Exchange’s complex order book Opening Process offers customers the ability to queue orders or submit Complex Instrument Creation (CIC) requests during pre-market and during an intra-day halt period. Instruments with a stock leg will not open until all the individual option leg series have opened on the simple book, and the first trade and LULD bands have been published for the underlying equity leg by the primary listing market. Complex Orders with Stock legs will COA immediately following the Opening process if marketable.
