The handling fee is charged by the exchange and the futures company that opened the account. The above picture shows the charging standard of the exchange. Pigs are charged in proportion, accounting for 2% of the transaction amount (4% if it is flat today). Note that this is the transaction amount, that is, the value of the goods, not the deposit.

Some account-opening futures companies need to ask your account-opening personnel. Each company and each customer may be different.
