The recent market situation should have taught countless friends who chase shorts and rises. They will be shocked several times a day. This is the case when the market fluctuates greatly, especially when there are both bad news and good news. In fact, the best way is to do nothing, observe the market, read the news, analyze the data, increase your learning ability, and wait for a certain opportunity to re-enter the market. Frequent trading will only damage your principal more and more. Even if you are lucky enough to make money, you may lose it back the next time you go crazy. People who do nothing and outperform 90% are particularly evident in the current market.
