You can make money by shorting accurately. Short-selling futures means that investors expect the futures market to fall in the future, sell their own standard contracts at this price, buy them after the market falls, and earn the difference. Therefore, if the judgment is accurate, shorting can make money. Generally speaking, to make a profit by shorting means that investors use various methods to push up the price of a futures commodity in advance when they predict that the market will fall in the future, resulting in a false development trend that the futures commodity will continue to soar in the future, and then sign futures contracts to sell this kind of thing at a high price, and then buy back the same number of contracts in the future. The difference is the money earned by investors.
