Candlestick formation · Bearish
What is it, in one line
A down candle that opens exactly at its high, so it has no upper shadow.
Bearish · 1 candle · verdict: rule and thresholds below
A down candle that opens exactly at its high, so it has no upper shadow. 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
One candle closing below its open, with the open at or within a hair of the high. Sellers were in control from the first tick; the lower shadow is unconstrained, so the close need not be the low.
The traditional claim
Read as selling pressure present from the open, and quoted as the weaker sibling of the full marubozu.
How this detection is wrong
Measured as a fraction of range rather than as an exact equality, for the same tick-size reason as its bullish twin.
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 |
|---|---|---|
| maxShadowPct | each wick, at most, as a share of the range | 0.02 |
| minBodyPct | body, at least, as a share of the range | 0.6 |
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 Bearish Opening Marubozu candlestick pattern?
One candle closing below its open, with the open at or within a hair of the high. Sellers were in control from the first tick; the lower shadow is unconstrained, so the close need not be the low.
Is the Bearish Opening Marubozu bullish or bearish?
It is read as bearish. Read as selling pressure present from the open, and quoted as the weaker sibling of the full marubozu.
When is a Bearish Opening Marubozu not a Bearish Opening Marubozu?
Measured as a fraction of range rather than as an exact equality, for the same tick-size reason as its bullish twin.
How is a Bearish Opening Marubozu detected?
As an executable rule over open, high, low and close, with 2 named parameters — including each wick, at most, as a share of the range 0.02, body, at least, as a share of the range 0.6 — 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.
This formation has a mirror
Its mirror is the same construction inverted, read in the opposite direction. Everything the two rules test is the same except the sign, so the thresholds on this page apply equally to both — and a result measured for one says nothing about the other until the other is measured too.
