METHODS OF DETERMINING TRANSACTION PRICES ON ELECTRONIC TRADING EXCHANGES

摘要

A method of determining transaction prices on an electronic trading floor, or exchange, requires every participating trader to maintain a bid for each share being traded on the exchange except for those shares held by the trader. Bids are maintained in an electronic database, but not disclosed to traders. When a trader desires to liquidate a share, whether asset or liability, the method enables the trader to liquidate at the most favorable bid. Trading is thus accomplished on the electronic floor without using any offers and without disclosing bids.
