Long black line

long down bar; BOTH shadows ≤ shortShadowRatio × range

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

long down bar; BOTH shadows ≤ shortShadowRatio × range

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
  • shortShadowRatio = 0.1
  • longBodyRatio = 1

Prior trend

none · No prior trend is tested. The rule reads the shape alone.

Several names can describe one bar. This one belongs to the long-down-body family with Bearish marubozu, Bearish belt hold, Bearish closing marubozu; anything that tallies patterns counts the family once per bar, so one candle never reads as several detections agreeing.
