To understand the meaning of "selling futures", we need to understand the concept of futures first. Futures refers to a contract in which both parties agree to buy and sell a certain number of commodities, indexes or financial products at an agreed price at a certain time in the future. Therefore, selling futures means selling a commodity, index or financial product at a specific time in the future. The purpose of selling futures is often to hedge or speculate.

In "selling futures", the seller has to bear the huge losses that may be brought in the future. For example, if the seller sells futures and the market price rises sharply in the agreed future time, then the seller needs to buy the commodity at the agreed price. And if the market price rises sharply, the seller may have to pay much more than the reward he gets from selling futures. Therefore, selling futures is a high-risk and high-return trading activity, which needs the support of experience and skills.

In a word, "selling futures" is an important trading activity in the futures market. Its purpose is often to avoid risks or make huge profits. However, in this process, the seller has to bear very high risks. Therefore, when selling futures, we should strictly abide by the rules and plans and master certain trading skills. Only in this way can we succeed in the futures market.
