Marubozu — what it is and how to use it in trading
Definition
Marubozu is a candle with (almost) no wicks: the bullish version opens at its low and closes at its high, the bearish version opens at its high and closes at its low. The bar's entire range is body — one side dominated the whole period with no pushback at all.
How it works in the builder
marubozu_bull/marubozu_bear take a threshold parameter (default 0.9): the body must cover at least that fraction of the candle's full range, allowing a small tolerance for a barely-visible wick rather than requiring a literal zero-wick match.
What it looks like on the chart
A single solid rectangle with no visible tails — the strongest single-bar statement of directional control the builder can flag.
Typical use
Typical condition: marubozu_bull == 1 as confirmation of a strong momentum move/breakout, often combined with rising volume (e.g. obv making new highs) or a breakout above a resistance level.
Common pitfalls
A single Marubozu says nothing about what comes next — it's a snapshot of one bar's dominance, not a forecast; on its own it precedes a continuation about as often as a reversal on exhaustion, so it needs trend or level context to be actionable.
