DIVERSE OPTIONS ORDER TYPES IN AN ELECTRONIC GUARANTEED ENTITLEMENT ENVIRONMENT
摘要
An enhanced system and method for handling, matching and executing a diverse group of limit-priced orders in an electronic options environment is disclosed. Most of the order types disclosed are automatically repriced and reposted as the NBBO changes to increase their execution opportunities. Market maker entitlements are integrated with the order processing, so that the market maker is guaranteed an allocation of the trade if the market maker is at the NBBO when an order priced at or better than the NBBO is received. Once posted to the order book, the displayed price of an order may be eligible for preferential execution in a market maker entitlement process, regardless of whether the displayed price is original or has been automatically repriced.
