Candlestick shape · 1 bar · ▼ bearish
Definition
The textbook label for this shape is ▼ bearish. The label describes the shape; it is not an instruction.
QuantZ does not claim this shape has predictive value. The detector reports that the bars met a definition; it says nothing about what follows.
The rule the detector applies
doji; lower shadow ≤ shortShadowRatio × range; upper shadow ≥ longShadowRangeRatio × range; bearish only after a rise, else neutral
Thresholds are named by the option key the code reads. The values below are the ones the detector ships with, read at render from its defaults; every ratio is measured against the bar’s own range or the trailing average body, so the same numbers apply to a low-priced stock and to a high-priced coin.
- dojiBodyRatio = 0.1
- shortShadowRatio = 0.1
- trendLookback = 5
- longShadowRangeRatio = 0.6

Several names can describe one bar. This one belongs to the doji-bar family with Takuri, Rickshaw man, Long-legged doji, Dragonfly doji, Doji; anything that tallies patterns counts the family once per bar, so one candle never reads as several detections agreeing.
