Futures, whose English name is futures, is completely different from spot. Spot is actually a tradable commodity. Futures are mainly not commodities, but standardized tradable contracts based on some popular products such as cotton, soybeans and oil and financial assets such as stocks and bonds. Therefore, the subject matter can be commodities (such as gold, crude oil and agricultural products) or financial instruments. The delivery date of futures can be one week later, one month later, three months later or even one year later. A contract or agreement to buy or sell futures is called a futures contract. The place where futures are bought and sold is called the futures market. Investors can invest or speculate in futures.
