double auction market
Definition
A system in which buyers enter competitive bidders and sellers enter competitive offers simultaneously, as opposed to the over-the-counter market, where trades are negotiated. Examples are the NYSE and the AMEX. A double auction market can also be carried out by open outcry, in which buyers and sellers call out prices that they are willing to buy and sell at, and a match is made if a buyer and seller call out the same price. Double auction markets usually feature a large number of buyers and sellers, and thus participants tend to incur lower transaction costs than in the over-the-counter market. also called auction market.
