Last week, the peak range of the rebound after the plunge of 48888 was basically established. In other posts, the reference of the extreme high point: 62300 (actually 62800) was given. Now it has fallen to 5.6w again, and some people regret not selling at a high position. This is unnecessary. The short-term and medium-term lines should follow the rebound wave and the falling wave. If you don't make a decision, you will suffer from the chaos. There is no need to worry about the changes in the short-term and medium-term lines. You should give yourself a positioning. You should follow the rules for any cycle of trading without looking ahead and behind. There are many opportunities. Returning to the essence, it is nothing more than making money, no matter how high or how low it rises.
