How to determine the validity of the support level?

Many people only focus on whether there is a "support line" when looking at support, but they overlook a more important point: although it is also support, the reliability varies completely depending on the confirmation method.
In the worst-case scenario, the price confirms the support level only to be quickly pushed back down. A long upper shadow is a typical characteristic: it indicates that buying attempts are trying to take over, but the strength is insufficient, and they are directly suppressed by selling. This type of support, even if drawn accurately, does not have entry value.
In moderate situations, a solid rebound candle appears after the price approaches the support level, but there is still an upper shadow, indicating average upward momentum. It tells you that buying pressure is trying, but whether it can continue needs confirmation from the following candles. The market often rebounds from here. However, the sustainability is not that stable.
In the best case scenario, a clean reversal candle appears after the support is confirmed, with no upper shadow and a clear body. The price touches the support and is immediately caught by buying pressure, pushing directly towards the previous high. This structure is not just a rebound; it resembles a true bullish takeover.
Lastly, and most importantly, only after a rebound (waiting for the right side) can we stabilize the determination of the support's validity; otherwise, it is just "betting" on its validity. How to determine the validity of the support level?
Many people only pay attention to "whether there is a support line" when looking at support, but overlook a more important point: although it is the same support, different confirmation methods have completely different reliability.
