Candlestick shape · 1 bar · ▲ bullish · on the chart IH

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

not a doji; upper shadow ≥ longShadowRatio × body; lower shadow ≤ shortShadowRatio × range; after a decline

Thresholds are named by the option key the code reads, and the list below is every option this shape’s detector reads, taken from the detector’s source. The values are the ones it ships with, read at render from its defaults. Each ratio compares parts of the bars (a body, a shadow, a range) with one another, or with the average body or range of the bodyAvgPeriod bars before them; bodyAvgPeriod, trendLookback and hikkakeConfirmBars are counts of bars. So the same numbers apply to a low-priced stock and to a high-priced coin.

  • dojiBodyRatio = 0.1
  • longShadowRatio = 2
  • shortShadowRatio = 0.1
  • trendLookback = 5

Prior trend

required · A prior move is required: the rule reads the bars before the shape, and the shape is not reported without it.

Counted once with

Several names can describe one bar. This one belongs to the upper-shadow family with Shooting star, Long upper shadow; anything that tallies patterns counts the family once per bar, so one candle never reads as several detections agreeing.
