Futures are different from stocks. There are many futures, and there are also short sellers. At any moment, the number of parties and short parties is equal, and there will be as many short parties as there are.

If the copper price remains unchanged, but the futures price fluctuates, then of course some people will make a profit and some will lose money.

After the copper price falls, the short seller of futures will make a profit, and many parties of futures will lose money, and the lost money will go into the pocket of the profitable person.

Every futures contract is produced by the signing of both parties and the empty side. This kind of contract can only be signed by both parties, so the original contract is provided by both parties and the empty party.

If you are engaged in futures speculation, the exchange will close the position one month before the expiration, and will not let you hold it in the delivery month at all. If you want to have a position to be delivered, you need to be qualified. You need a legal person to open an account, whether the company's qualifications meet, and what is the minimum capital. Otherwise, don't worry. The exchange will close its position one month before the expiration.
