$M The review of m at that time was indeed not understood or only partially understood. I used to understand it but then could not understand it again. The knowledge about price behavior is too vast and has too many details. Some things are forgotten if not used for a long time, and then I had to go back and learn it all over again. In any case, I should not make mistakes in this kind of market in the future.

Back to the market, after 30 consecutive bearish K-lines on the daily chart, the largest bearish K-line appeared. This type of K-line is called a surprise K-line or a gift K-line for bears. The bears and institutions in the market will take profits using this K-line. The bulls also know that the bears will take profits, so they anticipate a two-phase 10k increase. The first target for the bulls is the shadow gap, and the second target is the closing price of the large bearish K-line. This large bearish K-line is not only a gift K-line but also represents a selling climax in the trend and a exhaustion gap, so the market will sell at the peak's rise and fall point. The K-line is the operating code of the market; each K-line does not appear out of thin air. Each K-line, even when switched to 5 minutes, is the result of institutional game play.

Finally, looking at the strategy, I should have called for a long position at the double bottom. The background of this double bottom supports a higher probability of reversal, but I indeed did not see it and missed it.

I also directly looked at several cases of gift K-lines; they basically all showed a significant rise or fall after 30 K-lines, testing the closing or opening of the large K-line. These things are all the codes for market operation, absolutely rational.
