Since you asked, I will answer with you. Spot is a physical transaction. For example, if you want to buy or sell corn, you should first look for demand units such as wineries, starch factories and feed factories to receive the goods, and then go to supply units such as grain exchanges or grain purchasing points. Then, according to the middle price difference, the profit is calculated by subtracting various expenses in the middle, and the corn is transported from the supplier to the demanding unit to earn the price difference. This is a spot transaction of grain. Of course, you can also sell your bill of lading to others at a high price, which is relatively simple. In short, no matter what means you use, spot trading is inseparable from physical objects (short-term supply and purchase).

Futures are spot derivatives. The so-called futures, as the name implies, are commodities that are stipulated to be delivered in a certain period of time in the future, but in fact they are a standardized contract that can be repeatedly transferred and bought and sold.

Finding prices, avoiding risks and investing in tools are its main functions.

Futures are based on the spot, and at the same time provide a stable role for the spot.
