Candlestick formation · Bullish
What is it, in one line
Three consecutive dojis at the bottom of a decline.
Bullish · 3 candles · verdict: rule and thresholds below
Three consecutive dojis at the bottom of a decline. The engine checks the formation as an executable condition over open, high, low and close, with a trend filter applied before the count is kept.
Method
Three dojis in a row, with the middle one’s body sitting clear below both neighbours. Three consecutive sessions of complete indecision, the middle one at a lower level.
The traditional claim
Traditionally described as extremely rare and a strong reversal. Rarity is easy to verify; strength is not.
How this detection is wrong
Three dojis in a row is already unusual; requiring the middle to gap makes it rarer still. Expect counts near zero on most instruments.
Published so the count can be reproduced. Every figure below is a parameter of the rule, not a preference: change one and the occurrence count changes with it.
| Parameter | Meaning | Default |
|---|---|---|
| trendPeriod | bars of prior trend inspected | 5 |
| maxPriorSlope | prior slope must be below | -1 |
| maxDojiBodyPct | body small enough to count as a doji | 0.05 |
| minGapAtr | gap between bars, at least, in ATR | 0 |
| atrPeriod | bars of ATR used to size everything below | 14 |
These share enough geometry that a detector can return more than one of them on the same bar. The engine reports every match rather than picking a winner.
Every pair on the site that can be mistaken for another, and what separates each: the look-alikes index.
Three dojis in a row, with the middle one’s body sitting clear below both neighbours. Three consecutive sessions of complete indecision, the middle one at a lower level. The detector also requires a prior downtrend, so the same shape in the wrong context is not counted.

As an executable rule over open, high, low and close, with 5 named parameters — including bars of prior trend inspected 5, prior slope must be below -1, body small enough to count as a doji 0.05 — all published on this page so the count can be reproduced. Strict and loose variants are defined as well, so the sensitivity of the count to those thresholds is visible rather than assumed.
Measurement pending re-run
No hit rate is published here yet. The run that would supply one was computed on engine ca6d9e36c81c; the engine is now cfb08765de7c. Its candlestick rows included the still-forming bar, and it predates the chart formations entirely, so those figures have been withdrawn rather than published with a caveat. The definition above is unaffected: it is what the detector tests, and no re-run changes it.
Same shape, opposite reading
The shapes are close, and the prior trend is what decides which one fired: this rule requires a preceding downtrend, its mirror a preceding uptrend.
Bearish Tri-Star: Three consecutive dojis, the middle one gapping above the other two.
