Abandoned Baby Pattern: the rare three-bar island reversal
A doji isolated from the bars on both sides by real gaps — the strictest and rarest of the standard three-bar reversal patterns.

Open the chartWhat it measures
An abandoned baby is a strong trend bar, followed by a doji that gaps away from it on both sides, followed by a strong bar in the opposite direction that also gaps away from the doji.
It measures an island of indecision completely isolated from the trend on both sides — the strictest three-bar reversal definition in common use.
How it is calculated
These are the steps Basis performs, verified against the published definition.
- 1
Bar one continues the existing trend with a large body.
- 2
Bar two is a doji that gaps away from bar one — no overlap between the two ranges.
- 3
Bar three is a large body in the opposite direction of bar one, gapping away from the doji with no overlap.
How to read it
- When it appears with true gaps, it is one of the more reliable single-setup reversal patterns precisely because the strict conditions filter out almost everything else.
- On a continuous market the true-gap requirement is rarely met exactly, so most flagged occurrences are a looser, weaker version of the strict pattern.
Where it misleads
This pattern was defined for gapping markets. Crypto trades continuously, so real abandoned babies are uncommon here — most matches on a crypto chart satisfy a relaxed overlap condition rather than the true isolated-island definition, and should be read with that in mind.
