Hello, for example, I'm going to buy 5 tons of wheat from you at a price of 2000 yuan per ton in one month. Now I tell you, you should take good care of the goods for me. I'm worried that you will raise the price for me after one month, and you're worried that I won't buy it from you after one month, so the exchange has drawn up a contract for us. The price, quantity, quality and time in the contract are clearly written. We all agree and just wait. In the meantime, if I don't want to buy, I can only sell this contract to an investor who needs this batch of goods. If you don't want to sell, you can only transfer this contract to the investors who need to sell this batch of goods, and the futures exchange is a centralized trading place where all futures transactions are carried out. Of course, the actual futures trading shows that the contract is not designed for investors alone, but it is usually set, and you can find the contract you need to trade in it.

Stock index futures are standardized futures contracts with stock price index as the subject matter. Stock index futures is a kind of financial futures, which is generally bought for hedging, that is, the operation of buying low and selling high to obtain the difference.

The implementation of margin trading system in futures trading is equivalent to the introduction of leverage mechanism, which multiplies the risks and benefits, which is naturally more risky than stock trading.

If you don't know the basic knowledge of futures, you can ask me. The low commission account is private.
