Futures and spot are completely different. Spot is actually a tradable commodity. Futures are mainly not commodities, but standardized tradable contracts with some bulk products such as cotton, soybeans and oil and financial assets such as stocks and bonds as the targets. Therefore, the subject matter can be commodities (such as gold, crude oil and agricultural products) or financial instruments.
Stock trading is the act of buying and selling stocks issued by listed companies. The core content of stock trading is that investors use the bid-ask spread to achieve arbitrage by trading stocks in the securities market. The rise and fall of stock prices change with the fluctuation of the market. The fluctuation of stock price often shows the characteristics of differentiation, which stems from the concern of funds, and the relationship between them is like the relationship between water and ships.
