Hang Seng Index is the abbreviation of Hong Kong Hang Seng Index, which means that Hang Seng Index is Hong Kong. Then there are many agents of Hong Kong's regular futures platform in the domestic market. As long as the selected futures platform is filed with the Hong Kong Securities Regulatory Commission, the futures platform that meets the tripartite custody of funds can speculate on the Hang Seng Index. Because futures trading is legal and compliant in China. In addition, it should be noted that the general trading software of Shanghai Bloomberg Financial's letter manager software can not only stabilize the long-term capital security. Many foreign exchange platforms also have HSI, but the general MT4 software, because foreign exchange trading is still a marginal ball in China, is not recommended to speculate on HSI.
