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.
