call market(redirected from Walrasian Markets)
An exchange or place on an exchange where trading occurs only at particular times, rather than throughout a trading day. On a call market, brokers take orders to buy and sell securities, record them, and execute orders at the appropriate time along with other brokers. Call markets are most common where there is little trading volume.
A market in which trading in individual securities occurs at specific times as opposed to continuously. In a call market all orders to buy and sell a particular security are assembled at one time in order to determine a price at which most of the orders can be executed. The participants then move on to a different security. Call markets are frequently used in situations in which there are few securities and participants.
