The leverage effect in futures is the original mechanism of futures trading, that is, the margin system. The "leverage effect" not only enlarges the tradable volume of investors, but also doubles the risks taken by investors.

Generally, the leverage ratio of domestic futures exchanges is 5% to 8%, that is, 20 to 12.5 times. Futures companies will add 2 to 3 points to prevent and control risks when opening an account.

The leverage of foreign exchange is 1: 30 in domestic banks and 1: 100 to 1: 1000 in the international market.
