What Is a Marubozu Candlestick?
Bullish marubozu open at the low and close at the high; bearish marubozu open at the high and close at the low. Full marubozu lack shadows entirely; opening or closing marubozu allow a shadow on one end only. The message is one-sided auction—buyers or sellers held control from open to close without meaningful rejection. Marubozu often appear on breakout days, trend acceleration legs, and news-driven gaps that trend in one direction. They are continuation signals in trends and thrust signals on breaks; reversal marubozu at extremes are less common and need context.
Compare body size to recent ATR—a marubozu should be unusually large versus neighboring bars to signal conviction.
How Do You Identify Marubozu in Practice?
Shadows must be negligible relative to body—rule of thumb under five to ten percent of total range. Body should be wide versus recent sessions. In uptrends, bullish marubozu breaking resistance show acceptance above the level. In downtrends, bearish marubozu through support show acceptance below. Volume expansion on the marubozu bar strengthens the signal. Small bodies without range expansion are not marubozu even if shadows are tiny. White marubozu after long bases can start markups; black marubozu after extended rallies can mark distribution days.
Partial marubozu with one small shadow still qualify if the dominant side controlled the session narrative.
What Context and Confirmation Matter?
Trade bullish marubozu long when breaking resistance in uptrend or clearing a base with volume. Trade bearish marubozu short when breaking support in downtrend. Counter-trend marubozu after extended moves may exhaust—wait for pullback rather than chase. Next-bar follow-through in same direction confirms; immediate inside bar after marubozu suggests pause. Combine with relative volume thresholds on breakouts. Gap-up marubozu opens need opening-range hold above gap for continuation longs.
Marubozu at all-time highs lack overhead resistance—use trailing stops rather than fixed resistance targets.
Where Do Stops and Targets Go?
Stops for bullish marubozu longs sit below the bar low or broken resistance retested as support. Bearish shorts stop above the marubozu high. Targets use measured move of the marubozu range added in breakout direction, or next major horizontal level. Because marubozu bodies are large, stop distance can be wide—reduce size. Partial profit at one ATR extension reduces give-back on mean reversion. Trail below higher lows after bullish marubozu in trends.
Chasing extended marubozu far from breakout level worsens risk-reward—prefer pullback entries to the break zone.
When Do Marubozu Signals Fail?
False breakouts produce bearish marubozu that reverse next day—classic bull trap if close back inside range. Low volume marubozu on holidays lack participation. Illiquid gaps create artificial full bodies. Exhaustion marubozu at parabolic tops fade sharply. Confusing small-bodied bars with marubozu leads to overconfidence. News reversals overnight gap against the marubozu direction. Treat marubozu as strength evidence at levels, not immunity from reversal.
Close back inside the broken level within two sessions often invalidates the breakout marubozu thesis.
