Trading System
SGX Securities Trading provides a sound and efficient trading infrastructure that enables Member Companies easy and reliable access into its securities market. There are three channels to trade securities in SGX, namely, via SGXAccess, Singapore Exchange Securities Order Processing System (SESOPS) and Virtual Terminal Interface (VTI). Orders are routed through one of these accesses to the central trade matching engine, known as the Central Limit Order Book (CLOB), for the matching of trades before such information is transmitted to the CDP clearing and settlement systems.

CLOB is a screen-based computerized trading system. Under the CLOB System, workstations installed at brokers’ offices are linked directly to the Exchange’s computer system. Investors’ orders are keyed in and matched by the system and confirmations sent to the brokers immediately. The CLOB system maintains an order book for every traded stock and matches buy and sell orders. Each order in the order book has a limit price. This is the highest (for a buy order) or lowest (for a sell order) price at which the order can be executed. Orders in the CLOB system are held according to price, then time priority. All unmatched orders will lapse at the end of the day.
