In China's financial futures market, institutional investors are divided into special unit customers and general unit customers. Special corporate clients refer to financial institutions such as securities companies, fund management companies, trust companies, banks, social security companies, qualified foreign institutional investors and other laws, administrative regulations and rules that require separate asset management, and other corporate clients recognized by the Exchange; General corporate clients refer to institutional investors other than special corporate clients. Special unit customers meet the relevant provisions of the investor suitability system and can open trading codes for their trading applications without comprehensive evaluation.
