The essence of futures is to sign long-term contracts with others to buy and sell commodities (or stock indexes, foreign exchange, interest rates).

It is generally easy to understand how to do more. Let's take shorting wheat as an example (the seller may not have the goods in his hand when signing the sales contract).

Explain the principle of short position: when the price of wheat is 2000 yuan per ton, it is estimated that the price of wheat will fall. You signed a (first-hand) contract with the buyer in the futures market, for example, you agreed to sell him 10 ton of standard wheat at any time within six months at a price of 2000 yuan per ton. (the value is 2000× 10=20000 yuan. If the deposit is 10%, you should provide a performance bond of 2000 yuan, which varies with the contract amount. )
