WHY TRUST THE MARUBOZU?

The Marubozu is one of the most decisive candlestick patterns in technical analysis — here's the science behind it.

🕑️

Pure Price Action

A Marubozu has no upper or lower wicks, meaning buyers or sellers controlled price from open to close with zero hesitation — the cleanest signal in candlestick analysis.

📖

300+ Years of History

First documented in Japanese rice trading in the 18th century. Popularised in Western markets by Steve Nison in Japanese Candlestick Charting Techniques (1991).

Momentum Confirmed

When a Marubozu appears with high volume, it's a powerful confluence signal. Studies show strong-body candles have above-average follow-through rates.

🎯

Objective Detection

Unlike subjective patterns, Marubozu detection is mathematical and rule-based. MarubozuScan applies exact wick tolerance thresholds — no guesswork, no bias.

📊

Works Across Timeframes

Marubozu signals hold statistical significance on daily, weekly, and intraday charts. Whether you're a swing trader or day trader, the pattern carries meaning at multiple scales.

▲ BULLISH MARUBOZU

// Buyers controlled the entire candle function isBullishMarubozu(candle, tolerance) { const body = candle.close - candle.open; const range = candle.high - candle.low; const upperWick = candle.high - candle.close; const lowerWick = candle.open - candle.low; const bodyPct = (body / range) * 100; return body > 0 && bodyPct >= minBody && upperWick <= maxWick && lowerWick <= maxWick; }
Close must be higher than Open (green candle)
Body ≥ minimum body % of total candle range
Upper wick ≤ tolerance % of range
Lower wick ≤ tolerance % of range

▼ BEARISH MARUBOZU

// Sellers controlled the entire candle function isBearishMarubozu(candle, tolerance) { const body = candle.open - candle.close; const range = candle.high - candle.low; const upperWick = candle.high - candle.open; const lowerWick = candle.close - candle.low; const bodyPct = (body / range) * 100; return body > 0 && bodyPct >= minBody && upperWick <= maxWick && lowerWick <= maxWick; }
Open must be higher than Close (red candle)
Body ≥ minimum body % of total candle range
Upper wick ≤ tolerance % of range
Lower wick ≤ tolerance % of range

HOW TO FIND THE BEST SIGNAL

Not all Marubozu signals are equal. Use these professional filters to dramatically increase your signal quality and trading edge.

01

Set Body Strength ≥ 85%

A Marubozu with a body taking up 85–100% of the full candle range is far more significant than one at 70%. Use the Min Body Size slider — push it to 85%+ for quality-first scanning.

💡 Pro Tip: 90%+ body strength with near-zero wicks is the gold standard. Rare but extremely reliable.
02

Tighten Wick Tolerance to ≤ 3%

For highest quality, set Wick Tolerance to 1–3%. This forces the scanner to only flag candles where price barely wavered — pure directional pressure from open to close.

💡 Pro Tip: Start at 5% to discover signals, then re-scan at 2% to shortlist only the strongest ones.
03

Use Longer Timeframes for Higher Reliability

A Marubozu on a 7-day or 14-day candle carries far more weight than a 1-day candle. Longer candles represent sustained momentum. For swing trading, prioritise 7D or 14D signals.

💡 Pro Tip: Confirm a 14D Marubozu signal with a 1D signal in the same direction for maximum confluence.
04

Scan Across Many Coins

The more coins you scan simultaneously, the higher the chance of finding a textbook signal. Add at least 10–15 coins. Marubozu patterns on multiple correlated assets in the same direction indicate a macro trend shift.

💡 Pro Tip: If BTC, ETH, and SOL all show bullish Marubozu on the same 7D scan — that's a powerful macro signal.
05

Confirm with Support & Resistance

A Marubozu signal is strongest when it occurs at a key level — a breakout above resistance, a bounce off strong support, or a break through a previous high. Always check price context on a chart before acting.

💡 Pro Tip: A bullish Marubozu breaking above a multi-week resistance level is one of the highest-probability setups in technical analysis.
06

Apply Risk Management — Always

Even the cleanest Marubozu signal fails sometimes. Never risk more than 1–2% of your portfolio on any single trade. Set a stop-loss below the low of the Marubozu candle (bullish) or above the high (bearish).

⚠️ Reminder: This tool is for educational purposes. Always conduct your own research and consult a licensed financial advisor before trading.
