Doji candlestick: types, meaning and why context decides

A doji is a candle whose open and close are at, or very near, the same price, so the body is a thin line. It tells you that during that period neither buyers nor sellers ended up in control. That is all it tells you on its own. Whether a doji matters depends almost entirely on where it appears.

What makes a candle a doji

A candle has an open, a high, a low and a close (the OHLC values). When open and close coincide, the body disappears and only the wicks remain. In practice, an exact match is rare on liquid instruments, so traders accept a body that is very small relative to the candle's total range, for example less than about a tenth of it. There is no official threshold; be consistent with your own.

The four common types

The dragonfly resembles a hammer without a body; the gravestone resembles a shooting star without one. The logic is similar: a rejected attempt in one direction.

Indecision, not reversal

A doji is often described as a reversal signal. It is more accurate to call it a sign of indecision. The market paused. After a pause, a trend can resume, reverse or turn into a range. The doji itself does not choose between those outcomes.

What makes a doji interesting is the contrast with what came before:

• After a run of large bullish candles, a doji at a known resistance level suggests the buying pressure has at least stalled.
• In the middle of a range, a doji is ordinary. Ranges are full of them.
• On a quiet chart where most candles are small, a doji is barely different from its neighbours.

A worked example

AUD/USD on M15 rallies for five candles, each with a solid bullish body, into a level near 0.66500 where price turned down twice last week. The sixth candle is a long-legged doji: it pokes above 0.66500, falls back below the open, and closes almost exactly where it opened.

Reading it in context: a strong push, a known level, and a candle showing that the push met selling there. A trader would now watch the next candle. If it closes clearly bearish, below the doji's low, the idea of a pause turning into a pullback gains support; that sequence resembles an evening star.

The failure version: the next candle opens, dips briefly, then closes above the doji's high. The doji was a breath, not a top. The trend continues and the level breaks. Nothing in the doji itself distinguished the two outcomes beforehand, which is why confirmation matters.

Common mistakes

• Treating every doji as a signal. On low timeframes, doji appear constantly.
• Ignoring the level. A doji means far more at clear support or resistance than in empty space.
• Acting before the candle closes. A candle can look like a doji at second 40 and close as a full-bodied candle at second 60.
• Reading Heikin Ashi candles as regular ones. Heikin Ashi averages prices, so its small-bodied candles are not the same thing as a doji on a normal chart.

Short expiries and OTC

On S5 to M1 charts, a doji often reflects nothing more than a few ticks back and forth. The shorter the timeframe, the more doji you see and the less each one means. If you trade short expiries, many traders look for doji on M5 or M15 at clear levels, and use the lower timeframe only to see what happens next.

On Sky Trade's OTC instruments, prices are generated by Sky Trade's server and do not follow any real market. The model makes the next move unpredictable, so a doji there is simply a random series pausing, with no information about what comes next.

How to use it in the Sky Trade terminal

Use the Candles chart type rather than Heikin Ashi or Line, and turn on the candle timer in settings so you can see when the current candle will close. Mark the level you care about with a horizontal line before the doji forms, not after.
