Futures practitioners (brokers of futures companies with futures qualification certificates) can open stock accounts for stock trading. The Regulations on the Administration of Futures Practitioners and the Regulations on the Administration of Futures Trading only stipulate that futures practitioners shall not engage in futures trading as individuals or others, but there is no stipulation that they shall not speculate in stocks. Futures and spot are completely different. Spot is actually a tradable commodity. Futures are mainly not commodities, but standardized tradable contracts with certain mass 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.
