If we ignore the so-called retail sentiment, from the perspective of the market, when is it called right-side bottom-fishing?

Generally speaking, a good downtrend structure will be accompanied by 2-3 downtrend boxes, but the main thing is not the number of boxes.

But when does it appear - "higher highs and higher lows", which is a phenomenon of the downtrend structure being destroyed, equivalent to a reversal of the downtrend.

The left picture is a theoretical picture, and the right picture directly uses the leading brother $BTC as an example.
