If you are just speculating, you buy a futures contract; If you hedge and make physical delivery, you buy soybeans, futures contracts and subject matter. If you buy a contract, you buy the subject matter. If you want a theme, you deliver it; If not, close the position before delivery. At present, speculative traders are not allowed to make physical delivery, and speculative trading in the market is far greater than physical delivery. The futures market is set up to avoid long-term risks and find prices. In fact, the number of subject matter traded in futures exchanges is very small.
The delivery of the subject matter must arrive on the delivery date. You can buy and sell the subject matter on the delivery date. Prior to this, it was a standardized contract for sales targets. Before the delivery date, you have to pay the deposit, which generally fluctuates around 10%.
What you need to understand is that buying and selling futures is actually a standardized futures contract, and futures and spot are corresponding. A standardized contract is a contract for the sale of goods. The exchange stipulates the trading rules, commodity standards and delivery time, but it can be bought and sold only by paying a small amount of margin. Therefore, futures trading has leverage, which can enlarge funds and improve the efficiency of the use of funds.
