Futures have daily limit, and different futures have different daily limit, including stock index futures 10%, Shanghai gold futures' daily limit of 8%, and some commodity futures' daily limit of 7%, such as soybeans and corn.

It should be noted that if the futures margin is lost, investors will either choose to add margin or close their positions. If the losses are serious and the account funds cannot make up for the losses, investors need to make up for the losses, otherwise they will be investigated by law.
