The NASD Regulation Advanced Detection System (ADS) monitors trades and quotations in the Nasdaq stock market to identify patterns and practices of behavior of potential regulatory interest. ADS has been in operational use at NASD Regulation since summer 1997 by several groups of analysts, processing approximately 2 million transactions per day, generating over 7000 breaks. More important, it has greatly expanded surveillance coverage to new areas of the market and to many new types of behavior of regulatory concern. ADS combines detection and discovery components in a single system which supports multiple regulatory domains and which share the same market data. ADS makes use of a variety of Al techniques, including visualization, pattern recognition, and data mining, in support of the activities of regulatory analysis, alert and pattern detection, and knowledge discovery.
