Automatic Order Matching. A computerized screen-based trading method as provided by the ASSET system which allows brokers to electronically send buy or sell orders from their offices to the SET trading computer. The ASSET system implements an order queuing process and arranges the orders according to price-and-time priority. Orders are first grouped according to price with the best price taking precedence. Then, within each price group, orders are arranged according to the earliest time. Simultaneously, the ASSET system begins to automatically match the first buy and sell orders in the queue while at the same time confirming each executed transaction via the brokers' terminals.
