Futures and spot are completely different. 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.

Mainland futures refer to futures products listed on Dalian Commodity Exchange, Shanghai Commodity Futures Exchange, Zhengzhou Commodity Exchange and CICC. Hong Kong is mainly a variety listed on the Hong Kong Stock Exchange, just like A shares and Hong Kong stocks, but different. Domestic futures households cannot buy or sell Hong Kong futures products.
