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.

If all the funds of 50,000 yuan are used for stock index futures trading, the risks borne by traders are brought by stocks or commodities worth about 500,000 yuan, which magnifies the risks by about ten times, and of course the corresponding profits are also magnified by ten times.

Futures leverage is not only the fundamental risk source of futures trading, but also the charm of futures trading.

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