A Marubozu is a candlestick pattern with no upper or lower shadows, meaning the price opened at one extreme of the session and closed at the other without pulling back at any point. It is the candlestick equivalent of a clean sweep: buyers or sellers held total control from the opening bell to the closing price. The name comes from the Japanese word for "close-cropped" or "bald," which accurately describes a candle stripped of its wicks.
The Marubozu is one of the clearest momentum signals in technical analysis. Its absence of shadows tells you that the dominant side never gave ground during the entire session.
Every Marubozu is either bullish or bearish, and the distinction shapes how traders interpret and act on it.
A bullish Marubozu opens at its lowest price and closes at its highest. Green or white in color, it shows that buyers drove prices higher from the first trade to the last with no meaningful selling pressure at any point. When it appears during an uptrend, it confirms the strength of that trend. When it appears after a sustained decline, it can mark the beginning of a reversal.
A bearish Marubozu opens at its highest price and closes at its lowest. Red or black in color, it signals that sellers were fully in control throughout the session. In a downtrend, it confirms continued bearish momentum. At the top of an extended rally, it can warn of an impending reversal.
Not every Marubozu is perfectly wick-free. Traders recognize three common forms, each carrying a slightly different signal.
A Marubozu inside a sideways range is less meaningful than one appearing at a structural breakout level. Context is everything. Three situations produce the strongest signals.
First, a Marubozu appearing after a prolonged trend suggests that trend momentum is still intact. A bullish Marubozu in the middle of an established uptrend tells you buyers have not yet exhausted themselves. Second, a Marubozu at a significant support or resistance level carries extra weight. If prices have been rejected at a resistance zone four times and a bearish Marubozu forms on the fifth approach, that is a meaningful signal. Third, a Marubozu following a long consolidation period can mark the beginning of a genuine breakout rather than a false one.
Like all single-candle patterns, the Marubozu is not a complete trading system on its own. Combine it with supporting evidence before acting.
These two patterns sit at opposite ends of the market psychology spectrum. A long-legged doji has a tiny body and long shadows in both directions, reflecting maximum indecision. A Marubozu has a full body and no shadows, reflecting maximum conviction. When a Marubozu follows a long-legged doji, it often signals that the market has resolved its indecision and committed to a direction.
