2. The external market effectively hedges the domestic market risks and provides cross-market arbitrage opportunities. (If there is an overnight short position in the domestic futures market, the risk of the second sky position is inevitable, but the loss caused by the reverse of the second sky position can be avoided by appropriate hedging among the varieties corresponding to the external market to ensure the maximization of income and the minimization of risk. )
3. The outer disk is the global pricing center and price authority. Futures have a large number of spot traders, unlike domestic futures, which are purely speculative markets.
4. There is no limit to external price fluctuation, the price trend is continuous, and there is no gap risk.
5. The leverage of the outer disk is 10-25 times that of domestic futures and 7- 15 times that of domestic futures, so the utilization efficiency of funds is higher.
6. The external market has huge turnover, mature trading market and trading mechanism, strong liquidity, large market capacity and no control right.
