At present, the core trading system automatically matches orders under the rule of “price priority and time priority”, satisfying the needs of over 102 million individual accounts and over 80 million individual holding record. The daily processing capacity averages 180 million orders and 180 million trades, and the peak load performance reaches 100 thousand trades per second.

·The one-city-dual-center operation structure, which is connected by two land lines and two-way satellites is capable of preventing communication failover, while the cluster host architecture design, which backups each other, is capable of takeover in 1 minute without any data loss in case of failure. Only a few trading system in the world can achieve this capability.
 
·Compatible with industrial standards such as FIX, easy for domestic and international participants to access, supporting the international businesses.
 
·Support multi-environments, multi-exchanges and multi-markets, providing ideal infrastructure for simulated trading and exchange hosting business.

Orders can be sent to the SSE’s trading system through terminals either on the floor or from member securities companies. SSE owns a huge 3600-square-meter trading floor, which is the largest one in the Asia-pacific region. In addition, the largest domestic satellite and optical fiber communication network, which can disseminate the real-time transaction information across the country and the globe, has connected SSE with more than 5000 trading terminals.



SSE has taken the lead in establishing a nation-wide satellite telecommunication network with the most sophisticated equipment, the most complete range of functions, the largest number of users and the widest coverage. It consists of more than 4000 DMRs and 1000 two-way substations and provides high performance delivery of trading instructions, market data, clearance data and announcements. The ratio of safe operation of the communication system stays above 99.99% over years.



The functionality of SSE’s technical system is highly comprehensive. It can provide reliable and convenient trading services for investors with 5 types of instruments: stocks, bonds, funds, warrants and futures, and can support various trading modes such as the continuous auction mode, the call auction mode, the quote-driven mode and other additional trading modes. Many other non-trading modes can be supported too.

Versatile order types can be applied: market, limit, stop/stop loss, market or limit, iceberg. Moreover, customized order types can be supported by setting proper parameters such as running reference data, trading hour, and order validity span etc.
