A worked example that explains the rule, not a stock price. The circle marks the first close beyond the level. The blue line is the target. The orange line is the invalidation. Prices are in the right-hand column, and sessions sit under the volume bar.Hollow green candles closed above their open, and filled red candles closed below it.

What it is
Two bottoms of similar depth but different shapes: the first is sharp and narrow with a long lower shadow, called "Adam", and the second is rounded and wide and takes longer, called "Eve".
Sharpness in the first is panic where everything is sold at once, and roundness in the second is selling that fades quietly until sellers lose momentum. It reverses at tops with the same read: a sharp top, then a rounded top, and the trigger is a break of the separating low between them.
When the trigger starts and when it fails
Signal
A close above the separating peak between the two lows.
AdamA sharp drop that ends in a session with a long lower shadow · selling peaked, then price bounced right back.
Neckline peakA bounce that marks the decision level the breakout is measured from.
EveA slow return to the first bottom's zone, with the low rounding out over weeks · sellers fade without panic.
BreakoutA close above the neckline peak on high volume. Price often comes back to test it from above.
RetestA return to the neckline peak from above shows resistance has become support. A close back below it after the breakout weakens the pattern.
Recognition rules
Adam's low is sharp, lasts one to three sessions, and has a long lower shadow.
Eve's low is rounded and at least twice as wide as Adam's.
The two lows are close in depth: they differ by no more than 5% of the pattern height.
A separating peak between the two lows, from which the breakout and target are measured.
Volume rises as the separating peak breaks upward.
There is a clear stretch of time between the two lows. Two lows touching in time are one choppy low, not a two-low pattern.
Measuring the target
Pattern height, meaning the separating peak minus the lower of the two lows, is added to the separating peak. In the example the separating peak is at $41.6 and the lower low at $31.2 ⇐ a target at $52.0. Invalidation is a close below the lower of the two lows.
Where it fools you
A sharp second low like the first is not this pattern, and buying before the close above the separating peak is buying inside a decline.
Order is part of the definition: a rounded low followed by a sharp one is a different pattern with a weaker read, and calling it "Adam & Eve" mixes up two reads.
A long lower shadow alone does not make Adam: a sharp low needs a fast drop before it and a fast bounce after it. Otherwise it is one volatile session inside a rounded low.

We do not detect chart patterns with a numeric rule: telling them apart takes judgment on the chart. Candlestick patterns with a numeric rule are detected daily by the candlestick pattern scanner.
The mirror image: the Adam & Eve Double Top
The same pattern turned upside down, with the same rules in the opposite direction: what was a top becomes a bottom, and the trigger, target and invalidation all flip direction.
