A Marubozu (Japanese for “bald”) is the most decisive single candle. The body fills the entire range — little or no wicks on either end. Whichever side won the bar, won it from open to close with no resistance shown by the other side.
It’s the candle that screams conviction. When it appears in the right context, it’s often the start of a meaningful continuation move.
Two flavours:
• Bullish Marubozu: green candle, opens at the low, closes at the high, little to no wicks. Buyers controlled every tick of the session.
• Bearish Marubozu: red candle, opens at the high, closes at the low, no wicks. Sellers controlled every tick.
The strict definition allows tiny wicks (< 5% of the body); in practice, most traders accept a candle with very small wicks as a Marubozu. The principle is the same: no meaningful pushback from the opposing side.
Two things, both useful:
• Conviction. The winning side wasn’t challenged. The losing side didn’t even try to defend. This is rare; most candles have some wick.
• Momentum. The next few bars often follow the Marubozu’s direction. It’s a continuation signal more often than a reversal signal.
The most reliable use: a Marubozu printing in the same direction as the existing trend, after a pullback or consolidation. The candle confirms that buyers (or sellers) have decisively re-taken control after the pause. Often the start of the next leg.
A Marubozu against the trend (a strong red bar in an uptrend) is harder to read. It can mark a reversal, but more often it’s a single-bar shock that gets absorbed in the following sessions. Treat counter-trend Marubozus with caution.
The most common Marubozu failure: the candle prints late in a long trend, attracts buyers, then the trend reverses on the next bar. The Marubozu looked like “more of the same” but it was actually the exhaustion bar — the last burst of momentum before reversal. This is hard to avoid; the defence is to position size for being wrong and to honour stops.
The second failure mode: identification. Many candles with small wicks get called Marubozus when they shouldn’t be. Be strict: the wicks should be visibly absent, not just small.
Key insight: Most candles tell stories of compromise — one side pushed, the other pushed back. The Marubozu tells the opposite story: one side took the bar uncontested. That uncontested quality is what makes it actionable. The candle is a signal of conviction, not of reversal — trade it accordingly.
Strict Marubozus — truly bald candles with no wicks — are rarer than the term implies. On any chart, you’ll find many candles with “little” wicks that get casually labelled Marubozus. Be selective. The signal’s value comes from its scarcity; if you’re finding a Marubozu every other bar, you’re identifying noise.
