Candlestick formation · Bullish
What is it, in one line
A bearish engulfing that appears at the bottom of a decline, where it reverses rather than continues.
Bullish · 2 candles · verdict: rule and thresholds below
A bearish engulfing that appears at the bottom of a decline, where it reverses rather than continues. 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 white body fully covered by the black body after it, occurring after a fall rather than after a rise. Same shape as a bearish engulfing, opposite location, and by classical reading opposite meaning: the last selling rather than the first.
The traditional claim
Read as a bottom signal, the mirror of the last engulfing top.
How this detection is wrong
Shares its shape with bearish-engulfing and is separated only by the prior trend; the same warning applies as for the last engulfing top.
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 |
| atrPeriod | bars of ATR used to size everything below | 14 |
| maxPriorSlope | prior slope must be below | -0.5 |
| minPriorBodyAtr | the preceding body, at least, in ATR | 0.3 |
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.
What is a Last Engulfing Bottom candlestick pattern?
A white body fully covered by the black body after it, occurring after a fall rather than after a rise. Same shape as a bearish engulfing, opposite location, and by classical reading opposite meaning: the last selling rather than the first. The detector also requires a prior downtrend, so the same shape in the wrong context is not counted.
Is the Last Engulfing Bottom bullish or bearish?
It is read as bullish. Read as a bottom signal, the mirror of the last engulfing top.
When is a Last Engulfing Bottom not a Last Engulfing Bottom?
Shares its shape with bearish-engulfing and is separated only by the prior trend; the same warning applies as for the last engulfing top.
How is a Last Engulfing Bottom detected?
As an executable rule over open, high, low and close, with 4 named parameters — including bars of prior trend inspected 5, bars of ATR used to size everything below 14, prior slope must be below -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.
Last Engulfing Top: A bullish engulfing that appears at the top of an advance, where it reverses rather than continues.
