If the domestic futures margin falls below the minimum standard, it will be forced to close the position, or the available funds in the account are negative.

For example, for gold futures of Shanghai Futures Exchange, the minimum trading margin is 4% of the contract value, and for crude oil futures, the minimum trading margin is 5% of the contract value. The minimum margin of each product is different, and the minimum margin can be calculated according to the market price.

For example, the current price of crude oil sc2002 is 499.7, 1000 barrels per hand, 499.7x 1000x5%=24985, and the first-class crude oil needs a deposit of 24985 yuan.
