National Market System


Full Definition of National Market System


A US national market system was mandated by the Securities Act Amendments of 1975, the most important federal securities legislation since the 1930s. At the heart of the national market is the ITS, which began operation in 1978. Nine markets – the American, Boston, Cincinnati, Chicago, New York, Pacific, and Philadelphia and NASD over-the-counter market – are linked electronically by ITS computers. This allows traders at any exchange to seek the best available price on all other exchanges that a particular security is eligible to trade on. The national market system also includes a consolidated electronic tape, which combines last-sale prices from all markets into a single stream of information.
