As the core facilities of the markets, the central securities trading systems of stock exchanges have been upgraded continually.

To support various securities trading simulation experiments of the Chinese markets, referring to NGTS, the central trading system currently-used by Shanghai Stock Exchange, a PC-based simulation system is designed and implemented, which can support full market data distribution and multiple auction modes like call auction, continuous auction and hybrid auction and most of the cash product trading of the stock exchange. According to testing, the performance and functionality of the simulation system can compare to the genuine system and can support parallel extension.
