Forced liquidation refers to the behavior that members or customers of a futures exchange use their financial advantages to control futures trading positions or monopolize spot commodities that can be delivered, deliberately raise or lower futures market prices, hold excessive positions and deliver them, and force the other party to default or close positions at unfavorable prices for profiteering. According to the different operation methods, it can be divided into two ways: "more forced air" and "more forced air". Forcibly liquidating futures is an act that seriously disturbs the order of futures market and will do harm to society. Therefore, investors should abide by the provisions of the futures market, and may not take unfair means such as forced liquidation to obtain benefits.
