A dealer market is a market without centralized order flow. The NASDAQ is a dealer market.
NASDAQ is the largest organized stock market for over-the-counter or OTC trading. NASDAQ
is a computer information system for individuals, brokers and dealers. It connects more than
350,000 terminals and processes more than 5,000 transactions per second (Source: NASDAQ).
Securities traded include stocks, most bonds and some derivatives.

Examples include the NYSE, the American Stock Exchange (ASE), the Chicago Board Options
Exchange (CBOE), the Chicago Mercantile Exchange (CME) and others.

dealer in the market. The specialist is charged with maintaining a continuous, orderly market.
