Level-2 Real time Products(Data)

The market data products of the Shanghai Stock Exchange (SSE) include real-time Level-1 market data, delayed Level-1 market data and real-time Level-2 market data. Only qualified vendors are authorized to operate the above data. Eligible organization may submit application for license to SSE InfoNet Ltd. (SSE InfoNet).

SSE Level-2 market data is a fee-based value-added securities market data service launched by SSE InfoNet Ltd., a wholly owned subsidiary of SSE, in collaboration with several information service vendors. SSE InfoNet drew on the experiences of foreign securities market data services, pooled the collective wisdom of securities professionals and information service providers, and took more than one year to roll out the new market data.

Level-2 market data is helpful in developing the securities market, 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 market data (show2003) provided by SSE for the market, Level-2 contains far more rich information and is distinctively different in transmission and dissemination.

SSE Level-2 market data is transmitted through the international standard data interface (FIX-based STEP protocol) with excellent flexibility and scalability. It supports data resending mechanisms and ensures the completeness of information. It also employs security certification mechanisms such as user authority control and encryption.

4. Dissemination

SSE Level-2 market data is modeled on the international securities information industry chain of "stock exchange - information vendor - user". SSE InfoNet produces Level-2 market data and provides it to licensed professional information vendors, which, in turn, develop a wide range of products and deliver them to the market. End-users can choose appropriate products according to the value of information and their needs.
