To learn to trade by yourself: There is only one purpose of trading: to "make money", but this purpose often contradicts the bosses of the financial industry. Don't listen to those bosses and senior executives in the financial industry who sing about making profits every day, but their actions and thoughts are like a person smoking, drinking, staying up late, and indulging in vices, while preaching that "health is the most important thing". The means of trading is to hold a position, and the process of trading is to find weak hands. Of course, there are many weak hands in the world of institutional trading, such as backward information transmission and weak profit motives; the phenomenon of the survival of the fittest is particularly evident in the trading circle.
