Auction market

Auction market trading, sometimes known as open outcry, is the way the major exchanges, such as the New York Stock Exchange (NYSE) and the Chicago Mercantile Exchange (CME), have traditionally handled buying and selling.

Brokers acting for buyers compete against each other on the exchange floor, as brokers acting for sellers do, to get the best price. While the trading can be quite intense it is orderly because the participants adhere to exchange rules.
