Hedging: refers to the spot enterprises locking in costs and profits in the futures market. (For example, if you want to sell 10 tons of beans within six months, the current price is 100 yuan/ton, and you are afraid that the price will drop sharply in the future, so you short 1 lot of beans in the futures market. In this way, even if the price drops sharply in the future, although you earn less money in the spot market, there will be short-selling gains in the futures market. )

Debt-free settlement on the same day: after the daily trading, the Exchange will settle the profit and loss, trading margin, handling fees, taxes and other expenses of all contracts according to the settlement price of each contract on the same day, transfer the net receivable and payable at one time, and increase or decrease the member settlement reserve accordingly.
