The first is the difference in supervision. Domestic supervision is the supervision of the domestic securities regulatory commission. Most international futures are Hong Kong companies, which are supervised by the Hong Kong Securities Regulatory Commission. At the same time, they must issue permits. Secondly, in terms of handling fees, international futures charges are low, bilateral charges are flexible, domestic futures charges are high, and the operation is cautious. The domestic futures trading time is 4 hours, the trading threshold is low, the funds are convenient, and the leverage is 5- 10 times (so-called margin trading). The disadvantages are relatively small trading volume, discontinuous trading, short trading time and limited trading volume, which are easily influenced by domestic policies. International futures have almost all the advantages of domestic futures, with large trading volume, 24-hour system and many trading markets.
