The reverse head and shoulders is the bottoming mirror of the topping pattern: a low, a lower low, then a higher low, confirmed by a break up through the neckline.
The reverse head and shoulders — also called an inverse head and shoulders — is the bottoming version: a low, a lower low, then a higher low, under a neckline drawn across the two intervening peaks.

The logic runs the same way inverted. Sellers drive a low, then a deeper one, then cannot manage a third. The failure to make a lower low, right after making one, is what says the selling pressure is exhausted rather than merely paused.
Bottoming patterns are generally more reliable here than topping patterns, for a structural reason: a stock that has already fallen 80% has far less left to liquidate. Forced sellers — margin calls, fund redemptions, converting noteholders — eventually run out of shares, and the higher low is often the first visible sign that they have.

Confirmation is the break up through the neckline, ideally on expanding volume. These setups tend to surface on the reversals scan and the accumulation scan around the time the right shoulder forms — volume building while price stays flat is exactly what accumulation looks like on an indicator.
