Mr. Dashu: Your question is very good. China's stock market is developing rapidly, while the futures market is developing slowly, and the theory is even slower. China has only investors, not associate citizens. Therefore, there are not a few people who bring stock market thinking into futures market. Your asking this question shows that you have the ability to think independently. There is no short selling mechanism in China stock market. If you want to make money, you have to buy it, and so does the dealer. If retail investors want to make money, they can only follow Zhuang. It is the key to the success of retail investors to find out the intention and destination of the banker. Analyzing the turnover is an important method to analyze the banker's whereabouts. The enlargement of the transaction shows that someone is buying, who is buying? Gambling companies, of course. How much money do retail investors have? How do we expand our business? What did the dealer buy it for? Accumulate goods, raise goods and ship goods to achieve the purpose of making money. Volume is actually an indirect reaction of the banker's position. The increase of banker's position will inevitably increase. How else to ship? This is why the trading volume in the stock market is important. But it's not that important now. Bankers have learned to make fake transactions.
