Speculating futures is a high-risk and high-yield investment method, which usually requires buying contracts first and then selling them after the price rises to obtain income. But in some specific cases, investors will choose to sell first and then buy, which is the operation of "selling first and then buying". This kind of operation usually occurs when there is great uncertainty about the future trend of the market, and investors hope to lock in profits or avoid losses by selling first.

There are a lot of speculative funds in the speculative futures market, and different investors may have different forecasts for the future trend of the market. If one investor thinks that the market is going down and the other thinks that the market is going up, then the operation of selling first and then buying can play a role. Selling first can help investors lock in profits when prices fall and avoid taking risks when prices rise.

There are many skills in the operation of the futures market, and investors need to be extra cautious. For the operation of selling futures first, investors need to be clear about their risk tolerance and changes in market trends, and carefully formulate trading strategies. In the process of operation, investors should always keep calm and avoid making wrong decisions due to emotional fluctuations. Considering the market and its own factors comprehensively, investors can truly achieve the goal of maximizing profits.
