A doji forms when open and close are essentially equal — neither buyers nor sellers won the session. The shape of its shadows determines which subtype it is, and location determines whether it means anything at all.
Long-legged doji, dragonfly doji, gravestone doji, and four-price doji — shadow configurations and what each encodes about the buyer-seller battle
| Pattern | Confirmation | Volume | Reliability | Common Failure Mode |
|---|---|---|---|---|
| Doji (general) | Next candle's direction tells the story. A doji is indecision; the following candle resolves it. | Heavy volume on a doji is more telling than light volume — it means significant trading occurred without net progress, which is a stronger signal of stalemate. | The doji is a context signal, not a standalone trade signal. Reliability depends entirely on what surrounds it. | Traders act on the doji alone, before confirmation, and get whipsawed. |
| Dragonfly doji | Next candle closes above the dragonfly's body line. | Strong volume strengthens the bullish read — sellers tested the downside heavily and were absorbed. | Generally considered more reliable than a long-legged doji because the recovery to the open shows clear buyer dominance by close. | The low gets retested and breaks the next session. |
| Gravestone doji | Next candle closes below the gravestone's body line. | Heavy volume strengthens the bearish read. | Comparable to dragonfly in mirror — clear seller dominance by close. | The high gets retested and breaks the next session. |
| Long-legged doji | Whichever direction the next candle closes resolves the indecision. A bullish next candle confirms bullish intent; a bearish next candle confirms bearish intent. The doji itself carries no directional prediction. | Heavy volume on a long-legged doji is more significant than light volume — high-volume indecision means significant trading activity produced no net result, which is a sharper signal of stalemate. | No directional lean — reliability is context-dependent. The pattern itself signals symmetric indecision with no edge on either side. | Treated as a reversal signal when it is actually a continuation pause. Most mid-trend long-legged doji are noise. |
| Four-price doji | Not applicable — four-price doji are data artifacts of thin instruments. No actionable signal is present regardless of what follows. | By definition, very low volume. The pattern itself signals absence of participation. | No reliable signal content — appears only in extremely thin markets with negligible trading activity. | Misidentification as a meaningful signal. In thin instruments, a four-price doji is a data artifact. |
