With the approval of CSRC, there are six futures companies that set up branches in Hong Kong to handle foreign exchange business, namely nanhua futures, China International, yongan futures, Guangfa Futures, Green Futures and jinrui futures. Among them, nanhua futures is the fastest-growing foreign exchange, and it can't help but set up a branch in Hongkong and a branch in the United States, becoming a member of many foreign exchange exchanges. At present, not only foreign exchange futures can be traded, but also Hong Kong stocks and US stocks can be traded.
