The second category is a buy out signal that can be used but with a normal intensity K: It meets at least one of these two criteria:

Closes at the top, but the body is not that big, or
The body part is large, but it closes in an intermediate area. This signal indicates that there are indeed buyers in the market, but the strength is not as strong as in the first type. One must observe the environment before making a decision.
⚠️ Lastly, I want to remind you: in a clear bearish trend, the appearance of a long lower shadow is not necessarily a signal to buy out. It is more likely to be a bounce within the bearish trend.
[28/11, 2:26 p.m.] +52 55 6113 7052: This can be seen very clearly when comparing long and short cycles. In the long cycle, a bearish candle with a long lower shadow, in the short cycle, it is often just a normal bounce or a technical correction within a bearish trend.

That is to say, the trend in most cases has not reversed, it is only a temporary upward repair in a process of continuous price weakening, and not a true counterattack from buyers.
