No one can judge very accurately. For example, the main force of the stock was supposed to continue to fall, and the technical form was also very bad. As a result, there is a sudden big profit, and of course it is likely to change its strategy and raise it. The trend is determined by joint efforts, not a fixed form. Don't pursue this panacea.

Of course, there are some judgment skills, but they should be used flexibly. Take the decline as an example. For example, take a comprehensive look at where this trend is at the big level. What is the strength of the previous rise? What is the general environment of the market? Is the important support nearby? What is the trend of the same plate or the same theme? Wait a minute. I pay more attention to the role of various support lines. If the low point of consolidation happens to be on the important support line, then the possibility of an upward turn will be greater.

Then it is to raise the operation level a little, so that as long as you see consolidation and divergence, you can boldly buy, at least to ensure a secondary rise, right? As long as the level is enough, this rebound can earn enough even if it sells 3, so don't bother to guess whether it will reverse or continue to fall.
