A long-legged doji has a near-equal open and close with substantial upper and lower shadows; it records wide movement but does not predict a reversal.
A long-legged doji is a doji with a very small real body and substantial upper and lower shadows. It shows that price moved materially above and below the opening level but closed at or near the open for the selected period.
The shape is often described as indecision or a struggle between buyers and sellers. Its direct evidence is narrower: wide intraperiod movement produced little net open-to-close change. The candle does not reveal the sequence of the high and low, participant intent, or the next price direction.
For open (O), high (H), low (L), and close (C):
absolute value of (C - O);H - maximum of (O, C);minimum of (O, C) - L; andH - L.A reproducible screen states the maximum body relative to the range and the minimum upper- and lower-shadow proportions. It can also require minimum volume or range so a stale or barely traded candle does not qualify only because the open and close match.
Assume a one-day candle records:
| OHLC field | Price |
|---|---|
| Open | $100.00 |
| High | $108.00 |
| Low | $92.00 |
| Close | $100.20 |
The body is $0.20, the upper shadow is $7.80, the lower shadow is $8.00, and the full range is $16.00. The body is only 1.25% of the range, while substantial shadows extend in both directions.
This qualifies under many long-legged-doji screens. It does not show whether price traded to $108 first and then $92, or the reverse. That distinction can matter to execution and event analysis but is absent from daily OHLC data.
| Pattern | Upper shadow | Lower shadow | Body location |
|---|---|---|---|
| Standard doji | Present but not necessarily long | Present but not necessarily long | Varies |
| Long-legged doji | Substantial | Substantial | Often near the middle, but rules vary |
| Dragonfly doji | Little or none | Long | Near the high |
| Gravestone Doji | Long | Little or none | Near the low |
A dragonfly doji after a decline is commonly interpreted as a possible bullish-reversal warning because price recovered from lower levels. A gravestone doji after an advance is commonly interpreted as a possible bearish-reversal warning because higher levels were not retained. Neither interpretation is guaranteed, and reversing those directional descriptions creates a basic chart-reading error.
After an advance or decline, a long-legged doji can flag that the latest period differed from prior directional candles. Inside an already volatile trading range, the same shape may be ordinary rather than exceptional.
Compare the candle’s range with a defined recent baseline. A $10 range can be extreme for one security and routine for another. Volatility normalization can help, but the chosen lookback and measure must be stated.
The shape can also be distorted by:
Possible confirmation rules include a later close above the high, below the low, or beyond a nearby support or resistance level. “The next candle moved decisively” is not reproducible unless decisive has a numerical definition.
A breakout beyond the wide doji range can require a distant entry or stop. If the next session gaps beyond the trigger, the assumed chart price may not be available. A backtest should use only information known before the order and include realistic fills and costs.
