## Abstract

A system and method of allocating orders in an exchange configured for trading by a combination of electronic and open-outcry trading mechanisms is provided. One method includes permitting multiple quotes to be disseminated to the market, but limiting market making to only those entities having a physical presence on the floor of the exchange. Methods of enhancing the hybrid electronic and open-outcry exchange also include automatically eliminating crossed quotes and locked quotes while permitting certain orders to trade against locked quotes.

## Claims

determining, via a trade processor, whether at least a portion of the electronic orders qualify for immediate execution according to a first order routing rule or open-outcry trading according to a second order routing rule;
automatically allocating, via the trade processor, a portion of the electronic orders from the derivatives trade engine for immediate execution based on the determination according to the first order rule;
automatically allocating, via the trade processor, a portion of the electronic orders from the derivatives trade engine to a trading floor for open-outcry trading based on the determination according to the second order rule; and
automatically routing, via the trade processor, any remaining portion of the electronic orders to an electronic order book after the allocation of electronic orders for immediate execution and open-outcry trading.
