Teach a little trick, for example, after dropping 9000 points a few days ago, it started to rise. During the rise, I kept posting that it was unlikely to directly break through 100,000. There is actually a logic behind this. Whenever there is a rapid and significant pullback, even if it can rise later, it needs to undergo some short-term oscillation to digest. If one day you notice a large spike within the day that gets retracted, and continues to break upward sharply within two or three days, you must be cautious. The market can rise, but it is not far from the top; at the very least, it is a significant stage peak. The slight rise after the drop a few days ago indicates a higher probability of continued oscillation. Therefore, on the day it reached 98,000, I said it could short. This kind of certainty is quite high, the cost-effectiveness is great, and the probability of loss is very small. Remember this trick, and believe that one day you will encounter such a market.
