What is it, in one line
A doji gapping below a long red body.
Bullish · 2 candles · verdict: rule and thresholds below
A doji gapping below a long red body. 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
Two candles: a long down candle followed by a doji whose body sits clear below it. The first two thirds of a morning star, before the confirming candle arrives.
The traditional claim
Traditionally read as a warning rather than a signal — the selling stalled, but nothing has yet confirmed a turn.
How this detection is wrong
A doji star gaps away from the prior body; a harami cross sits inside it. They are mutually exclusive, and conflating them is common.
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 |
| 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.
Two candles: a long down candle followed by a doji whose body sits clear below it. The first two thirds of a morning star, before the confirming candle arrives. 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 warning rather than a signal — the selling stalled, but nothing has yet confirmed a turn.

As an executable rule over open, high, low and close, with 6 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.
