There is obviously only one contract for futures, so what if both buyers and sellers want to close their positions and withdraw from the market? The following description helped me correct my misunderstanding. 1. Every penny earned in futures must be in another person's pocket.

2. Only when there are multiple parties and empty parties, and the price is agreed, can the transaction be concluded. There are no buyers and sellers.

3. The most important function of futures is not for speculation, but mainly for hedging. You are a soybean oil producer. When you sign a spot contract with others, you have already set the price, but you can't buy all the soybean raw materials at once. So if soybean raw materials go up, won't your contract lose money? So the spot price at that time was 2200 yuan per ton, and the futures price in May was 2300 yuan per ton. Worried about rising prices, the factory bought100t soybean futures. In May, the spot price really rose to 2400 yuan per ton, while the futures price was 2500 yuan per ton. The factory then bought the spot, with a loss of 0.02 million yuan per ton; At the same time, the futures were sold, and the profit per ton was 0.02 million yuan. The two markets break even, effectively locking in costs.

4. When the market transaction is inactive or the amount of open contracts is low, it is normal that the transaction cannot be reached.
