The net retention of 70% to 90% general handling fee starts from 70% and the maximum is not more than 93%. Brokers' rebate consists of three parts at most, the first is the net retention of commission, the second is the return of exchange, and the third is the interest of funds. You need a lot of money to consider returning it to the middleman. The net retention of the handling fee is to collect the handling fee of the customer minus the net handling fee of the exchange, and the return of the exchange is the transaction. The amount of fees charged will be returned to the futures company in proportion, and the interest return, as the name implies, means that the interest of the client's funds will be returned to the brokerage company at the annualized interest rate every month.
