Short selling: selling at a high price and buying at a low price is also to earn the difference. Suitable for watching the falling market. Let me give you an example here, because it is difficult for investors who make stocks to understand the concept of shorting at first. For example, at present, affected by the epidemic situation at home and abroad, I judge that there is no sharp upward trend in crude oil futures, and it is expected to fall tomorrow. This is my choice to short 1 0,000 barrels of crude oil, which is primary crude oil. At this time, I went to the futures market. I sold the parting mold at 300 yuan per barrel. When the market fell to a barrel of 200 yuan, I bought it back and went back to the futures market. I made a difference of 100 yuan per barrel.

For example, the current price of sugar in the futures market is 6800 yuan, and it will rise to 6850 after 10 minutes. At this time, you think the price of white sugar will continue to rise. At this time, you can choose to buy sugar futures contracts at 6800. If the price continues to rise to 6950, you can choose to sell a sugar futures at this time, and you earn 1000 in the process.

If you are bearish at the price of 6750, you can choose to sell the sugar futures contract first even if there is no sugar futures contract. When the price drops to 6650, you can still earn the difference of 1000 yuan by buying the sugar futures contract and closing the position. In this process, although you don't have a sugar futures contract, you can choose to sell sugar futures. This operation is called shorting.
