Open Outcry

A system of trading on an exchange in which members stand on the trading floor and make orders to each other by crying aloud. Some open outcry systems have developed special sign languages so they can make and fill orders without needing to be heard over the noise on the trading floor. All exchanges were originally open outcry, but many have gradually shifted toward electronic trading.
