'''CATS (Computer Assisted Trading System)''' is an automated exchange system developed for the [[Toronto Stock Exchange]] in 1977. CATS was one of the first technologies allowing for a full automation of the price-setting process in a stock exchange. This technology was implemented in several other stock exchanges in the 1980s. In some cases, it was used as an assistance to [[Open outcry|open-outcry]], but in others it allowed for a full dismantlement of the open-outcry institution. The [[Paris Bourse]] purchased this system in the early 1980s and implemented it as CAC ([[Cotation Assistée en Continu]]).
CATS handled the process of order matching and price setting through a "[[double auction]]" [[algorithm]]. It is credited for having been the first system to allow for a full [[automation]] of the price setting process in a centralized, order-driven stock market.
