Stepping empty-When the stock price of a stock rises all the way, it is judged that the stock price will fall back in the afternoon, so the stock is thrown out, and I want to buy back the thrown stock at a low price. Who knows that the stock price has not fallen back, but it has been rising all the time. In this way, the "high throwing and low receiving" foot is considered as "high throwing".
