Candlestick formation · Bullish
What is it, in one line
A bullish harami confirmed by a third green close.
Bullish · 3 candles · verdict: rule and thresholds below
A bullish harami confirmed by a third green close. 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
A bullish harami — long down candle, small up candle contained inside it — followed by a third up candle that closes above the second candle’s close. The third candle is the confirmation the harami on its own does not have.
The traditional claim
Traditionally read as a confirmed version of the harami, and usually said to be more reliable for that reason. Whether the confirmation is worth what it costs in delayed entry is exactly the kind of question a test answers.
How this detection is wrong
Every three inside up contains a bullish harami, so the two detections overlap by construction. Comparing the two counts on the same data is how you price the confirmation candle.
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 |
| minFirstBodyAtr | first body, at least, in ATR | 0.5 |
| maxBodyRatio | body, at most, relative to the bar before | 0.6 |
| 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.
A bullish harami — long down candle, small up candle contained inside it — followed by a third up candle that closes above the second candle’s close. The third candle is the confirmation the harami on its own does not have. The detector also requires a prior downtrend, so the same shape in the wrong context is not counted.
It is read as bullish. Traditionally read as a confirmed version of the harami, and usually said to be more reliable for that reason. Whether the confirmation is worth what it costs in delayed entry is exactly the kind of question a test answers.

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, first body, at least, in ATR 0.5 — 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.
Three Inside Down: A bearish harami, then a third candle closing below the second.
