When everyone is trading, how do they judge the breakthrough or breakdown of some key price levels?

Let me share my method:

1. Temporary Breakthrough/Breakdown: The current real-time price crosses the key price level, but the candlestick has not closed;

2. Breakthrough/Breakdown: The closing price of the candlestick has only one that crosses the key price level;

3. Confirmed Breakthrough/Breakdown: A bullish candle with both opening and closing prices greater than the key price level confirms a breakthrough, while a bearish candle with both opening and closing prices less than the key price level confirms a breakdown;

The longer the trade and the lower the leverage, the more vague the judgment criteria tend to be, such as needing to wait for a daily or weekly confirmation of a breakdown to stop loss;

Conversely, the higher the leverage and the shorter the trade, the more immediate the judgment criteria need to be. If a pin bar is lost, that is also a necessary trading cost and should be regarded as a reasonable loss;

Lastly, I generally recommend choosing a vaguely correct right-side logic (leaning towards 3) when entering a trade, while when exiting to stop loss, try to choose an immediate left-side logic (leaning towards 1);

I wonder how you make your judgments?
