Hedging refers to the offsetting financial operation taken by investors to prevent adverse price changes. Usually in the spot market and futures market, two groups of transactions in opposite directions are carried out. Broadly speaking, it is to buy or sell commodity futures contracts with the same number of transactions in the spot market, but in the opposite direction, in order to hedge and close positions and settle the profits or losses arising from futures trading at a certain moment in the future, so as to compensate or offset the actual price risks or interests brought about by price changes in the spot market and stabilize the economic interests of traders at a certain level.
