What is an abandoned baby?
The abandoned baby is a rare three-candle reversal formation in the Japanese candlestick tradition: a trend candle, then a doji that gaps entirely away from it, then a third candle that gaps back in the opposite direction. In the bullish version a long down candle is followed by a doji whose entire range, shadows included, sits below the first candle's low; the third candle then gaps up and closes well into the first candle's body. The bearish version is the mirror image at a high.
The defining requirement is the double gap around the doji. Unlike the morning star or evening star, where the middle candle merely has a small body and the gaps are judged loosely on bodies, the abandoned baby demands that the doji's shadows share no overlap with the shadows on either side. That strictness is why the pattern is scarce in liquid 24-hour markets, where true gaps are uncommon, and why it appears mostly on daily charts of instruments with session closes.
Traders care about it because the structure encodes an abrupt, isolated consensus failure: the market gapped to an extreme, went nowhere for a full session, then gapped back the other way, stranding everyone who traded the extreme. It is the candlestick counterpart of the Western island reversal compressed to a single isolated bar.
How to identify an abandoned baby on a chart
The pattern is strict; most candidates fail on the gap requirements.
- 1Establish context: a bullish abandoned baby needs a preceding downtrend and a bearish one needs a preceding uptrend; the pattern has no meaning inside a range.
- 2Confirm the first candle continues the trend with a substantial real body.
- 3Check the middle candle: it should be a doji, or very close to one, and its entire range including shadows must gap clear of the first candle's range.
- 4Check the third candle: it must gap back in the reversal direction, again with no shadow overlap against the doji, and close meaningfully into the first candle's body.
- 5Reject candidates where the shadows touch; those are morning or evening star variants, still tradeable, but a different and weaker specification.
How traders use it
- As a high-attention reversal flag on daily charts: because the specification is strict and rare, many traders treat a true abandoned baby as worth acting on with less additional confirmation than common candles require.
- For stop placement: the doji's extreme is the natural invalidation point, since trade back through it puts price inside the abandoned zone and voids the isolation logic.
- With location filters: completions at prior support or resistance, or after an extended run, are graded above ones appearing mid-move, consistent with general candlestick pattern practice.
- With realistic expectations: rarity limits any statistical evidence, and on gap-prone instruments the pattern can simply mark event-driven volatility rather than a durable turn. The gaps can also fill later without the reversal failing immediately, which complicates gap-fill based management.
Abandoned baby vs similar formations
Morning star: The morning star tolerates shadow overlap and only asks for a small-bodied middle candle; the abandoned baby demands a doji fully isolated by gaps on both sides, making it a stricter and much rarer case.
Island reversal: An island reversal isolates one or many bars between two gaps at the same price zone; a one-bar island whose stranded bar is a doji is essentially an abandoned baby described in Western bar-chart language.
Tri-star: The tri-star uses three consecutive doji with the middle one gapping away; the abandoned baby needs full-bodied trend candles on both sides of its isolated doji, so the two encode different amounts of directional conviction around the turn.

Abandoned Baby FAQ
How rare is the abandoned baby pattern?
Genuinely rare, because it requires true gaps on both sides of a doji with no shadow overlap. On 24-hour markets such as forex and crypto the strict form almost never prints; it is mostly a daily-chart equity and futures pattern.
What is the difference between an abandoned baby and a morning star?
The gap discipline. A morning star allows the small middle candle to overlap the neighbors' shadows; the abandoned baby requires the doji to be fully isolated by gaps on both sides. Every abandoned baby would qualify as a star pattern, but very few star patterns qualify as abandoned babies.
Is the abandoned baby bullish or bearish?
Both versions exist. The bullish form appears after a decline with the doji gapping below, and the bearish form appears after an advance with the doji gapping above. The logic is identical: an isolated extreme that the market immediately rejects.
How reliable is the abandoned baby?
Its rarity makes robust statistics hard to compile, and no candlestick formation is dependable on its own. The strict specification does encode a real two-gap rejection, which is why practitioners tend to weight it above common reversal candles, while still demanding sensible location and defined risk.
