Overview
Four-Price Doji
Also known as: Horizontal Line Doji, Zero Range Doji, Flat Doji
The Four-Price Doji is the rarest doji variant where all four price points (open, high, low, close) are identical, appearing as a horizontal line and signaling complete market inactivity or perfect equilibrium.
The Four-Price Doji occurs when a security opens, trades, and closes at exactly the same price, with no deviation during the entire session. This creates a simple horizontal line on the chart with no body and no shadows. It represents the ultimate expression of market inactivity — either there was virtually no trading, or every buyer and seller agreed on exactly one price. While this pattern is generally considered the least reliable of all doji variants due to its association with illiquid conditions, it can occasionally appear in liquid markets as a sign of extreme balance before a significant move.
History & Etymology
The Four-Price Doji was recognized in classical Japanese candlestick theory as a sign of market dormancy. In modern markets, it is most commonly seen in thinly traded securities, pre-market sessions, or during holidays when participation is minimal.
Named for the fact that all four price components — open, high, low, and close — are at the same level, making it the simplest possible candle formation.
How It Forms
Formation Steps
- 1Single candle where open, high, low, and close are all the same (or virtually the same) price
- 2Appears as a simple horizontal dash on the chart
Prerequisites
- Extremely low liquidity or volume
- All four OHLC values must be equal or within one tick
- Can appear in any trend context
Confirmation Signals
- Normal trading activity resumes on the following session
- Breakout from the four-price level with volume
- Gap away from the level on the next candle
Invalidation Signals
- Another four-price doji follows (indicates the market is effectively closed)
- No volume increase on subsequent candles
- The level has no technical significance
Candle Breakdown
Four-Price Line
A horizontal line where open, high, low, and close are identical, showing zero price movement during the session
The market is completely inactive or in perfect equilibrium. There is no battle between buyers and sellers — both sides are absent or perfectly matched.
Psychology
The Four-Price Doji reflects total market apathy or perfect balance. There is no tug-of-war because one or both sides are simply not participating. This can signal a calm before a storm if it occurs in a typically liquid market.
Buyer Perspective
Buyers find no reason to bid prices higher and either stand aside or place orders at exactly the current level. Interest is minimal.
Seller Perspective
Sellers see no urgency to push prices lower and either refrain from selling or offer at exactly the current price. Selling pressure is nonexistent.
Smart Money Action
Institutions generally ignore four-price doji candles formed in illiquid conditions. However, if one appears in a normally liquid security, they note it as an extreme compression event warranting attention.
Retail Trader Trap
Retail traders may misinterpret a four-price doji as a powerful indecision signal. In reality, it usually just means nobody was trading.
Emotional Cycle
Trading Strategy
Aggressive Entry
Not recommended for the four-price doji alone — it carries too little information for directional trading.
Conservative Entry
Wait for normal trading activity to resume and apply standard analysis to the next meaningful candle formation.
The nearest significant support or resistance level.
1.5:1 risk-reward based on the wider stop.
Previous swing high/low beyond TP2.

Scale In Strategy
Not applicable — rarely traded as a standalone pattern.
Scale Out Strategy
Standard scaling approach if trading the breakout from the four-price level.
Risk Management
Volume Analysis
Volume Confirmation
Volume on the four-price doji is typically near zero. A volume return to normal levels on the next candle is necessary before any trading decision.
Volume Profile
The four-price doji contributes almost nothing to the volume profile. Focus on surrounding candles instead.
Volume Divergence
Not applicable — volume is too low during the doji to assess divergence.
Technical Confluence
Support Resistance
The four-price level itself can act as a minor support/resistance level in future trading sessions.
Fibonacci Levels
If the four-price doji occurs at a Fibonacci level, it may mark an important equilibrium point.
Moving Averages
Four-price doji at a major moving average suggests the market is perfectly balanced at a trend-defining level.
Rsi Confirmation
RSI is typically unchanged during a four-price doji session. Use surrounding candles for RSI analysis.
Macd Confirmation
MACD may show flattening during the four-price doji, confirming zero momentum.
Bollinger Bands
Bollinger Bands contract dramatically around the four-price level, creating a potential squeeze setup.
Vwap
VWAP equals the four-price level exactly, providing no intraday information.
Ichimoku Cloud
The doji contributes a flat point to all Ichimoku calculations, potentially flattening the Tenkan-sen.
Elliott Wave
Four-price doji can mark the exact terminal point of a corrective wave before the next impulse.
Wyckoff Phase
May represent a Test or Spring in Wyckoff if at a significant support level with extremely low volume.
Market Profile
Single price level creates a single TPO print — useful as a reference point but offers no profile structure.
Order Flow
Zero delta, zero cumulative volume delta. The absence of order flow is itself the message.
Open Interest
Flat open interest confirms no new positions were established during the session.
Multi-Timeframe Analysis
Higher Timeframe Alignment
A four-price doji on any timeframe is only meaningful if the higher timeframe shows it at a significant level.
Lower Timeframe Entry
On lower timeframes, the four-price doji period appears as a flat line with no structure to trade.
Timeframe Confluence
Not applicable — four-price doji rarely appears on multiple timeframes simultaneously except in truly dead markets.
Top-Down Approach
Use higher timeframe structure for context. The four-price doji itself provides no internal structure.
Statistics
Historical Examples
Thinly Traded ETF Four-Price Doji
failureA thinly traded ETF printed a four-price doji on the day after Christmas when markets had minimal participation. Trading resumed normally the next day with no directional significance.
Lesson: Four-price doji in illiquid conditions or holiday sessions carry no trading significance.
Pre-FOMC Four-Price Doji
successSPY printed a four-price doji on the hourly chart minutes before the FOMC rate decision. The subsequent candle gapped aggressively, delivering a tradable breakout.
Lesson: In liquid markets, a four-price doji before a catalyst signals the calm before the storm.
Penny Stock False Signal
failureA penny stock printed four-price doji candles on multiple days due to lack of volume. No directional signal was produced.
Lesson: Four-price doji in low-liquidity instruments are symptoms of illiquidity, not market indecision.
Variations
Near Four-Price Doji
Open, high, low, and close are within one or two ticks of each other but not perfectly identical.
Confusion Matrix
Patterns commonly confused with Four-Price Doji and how to distinguish them.
Neutral Doji
7000% similarA four-price doji appears as a flat horizontal line with zero range. A standard doji has at least some shadow.
Key Differences
- Standard doji has upper and/or lower shadows
- Four-price doji has no shadows at all
The Doji is the quintessential indecision candle where opening and closing prices are virtually identical, reflecting a perfect tug-of-war between buyers and sellers.
The Long-Legged Doji features extremely long shadows in both directions with the open and close near the center, representing the most extreme form of single-candle indecision and a potent warning of momentum exhaustion.
The Volatility Contraction Pattern (VCP) shows progressively smaller price swings as ATR declines, signaling that the market is absorbing supply and preparing for a significant directional breakout.
The Bearish Belt Hold is a single bearish candle that opens at its high and closes near its low with a long body, indicating that sellers dominated from the opening bell and controlled price action throughout the session.
The Bearish Closing Marubozu is a single bearish candle with no lower shadow — the close is at the exact low of the session. This indicates that sellers controlled the session and maintained pressure through the very last trade, a sign of strong bearish conviction.
The gravestone doji is a single-candle reversal pattern with the open, close, and low at the same level and a long upper shadow, resembling a gravestone. It signals that buyers pushed price higher but sellers reclaimed all gains by the close.
Pro Tips & Common Mistakes
Pro Tips
- Always check volume before interpreting a four-price doji — zero volume means zero information
- In liquid markets, a four-price doji is extremely rare and therefore more significant when it occurs
- Use the four-price level as a future reference point for support/resistance
- Combine with an event calendar to determine if the doji represents pre-event positioning
- Do not include four-price doji in pattern statistics or backtests — they distort results
Common Mistakes
- Assigning directional significance to a four-price doji formed in illiquid conditions
- Confusing a data error or bad tick data with a genuine four-price doji
- Attempting to trade based solely on the four-price doji without context
- Ignoring the volume context which is critical for this pattern
- Treating all doji variants as equally reliable
Advanced Techniques
- Use four-price doji as a filter — exclude these candles from pattern recognition algorithms to avoid false signals
- In high-frequency data, four-price doji on longer timeframes can mark institutional quiet periods worth monitoring
- Track the price level of the four-price doji as a potential magnet level for future price action
- Use as a volatility floor indicator — if even the four-price doji breaks a level, the move is genuine
Institutional Perspective
Institutions largely disregard four-price doji candles as they typically reflect market inactivity rather than meaningful positioning. The exception is when a four-price doji appears in a normally liquid instrument, which may signal that all participants are awaiting a specific catalyst.
Fun Facts
- The Four-Price Doji is the simplest possible candlestick — a single horizontal line with zero visual complexity.
- In liquid markets like the S&P 500, a true four-price doji on a daily chart has occurred fewer than five times in the last 50 years.
- Some charting platforms do not even render four-price doji candles, treating them as missing data.
