SSE Level-2 market data is a value-added securities market data service launched by SSE InfoNet Ltd., a wholly owned subsidiary of SSE,. SSE InfoNet drew on the experiences of foreign securities market data services, pooled the collective wisdom of securities professionals and information service providers.
Level-2 market data is targeted on institutional investors, by increasing market transparency, reducing irrational price fluctuations, and enhancing market activity. It will also satisfy diversified demands of various investors, help create the securities information service industry chain and facilitate the implementation of state policies on strengthening exploitation and utilization of information resources.
The launch of Level-2 market data is of great significance. It was a concrete move taken by SSE to serve the market and also an important step to raise the market service level and move towards internationalization. Compared with the existing real-time Level-1 market data provided by SSE for the market, Level-2 contains far more rich information and is distinctively different in transmission and dissemination.
