Candlestick shape · 1 bar · ▲ bullish
Definition
The textbook label for this shape is ▲ bullish. 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
dragonfly shape whose lower shadow is also ≥ veryLongShadowRangeRatio × the trailing average range; bullish only after a decline, 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.
- bodyAvgPeriod = 14
- trendLookback = 5
- veryLongShadowRangeRatio = 2

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