If futures are charged in both directions, a certain fee will be charged in the process of buying and selling. If futures are charged in a one-way way, they will only be charged when they are bought, and they will not be charged when they are sold. At the same time, the futures handling fee can be divided into two types: fixed fee = transaction procedure × handling fee per lot, and proportional fee = transaction price × handling fee rate × lots.

For example, if an investor invests in a futures, the handling fee is calculated according to the transaction amount. When the market price is 600 tons, he buys 10 lots, in which 1 lot is 100 tons, and the transaction handling fee rate is 0.5 ‰, then the handling fee for investors to buy is 600×10×.
