A bullish marubozu on the Nasdaq opens at the session low and closes at the session high, no meaningful wick on either end. Buyers didn't just win the day, they never lost control of it for a single tick worth mentioning. That's the rarest kind of candle on a chart, and also one of the easiest to misread, because total conviction in the moment doesn't always mean total conviction going forward.
What makes a marubozu different from a strong trend candle
Plenty of candles have big bodies and still carry a visible wick, a moment where the other side pushed back before losing. A marubozu has essentially none of that: open equals, or nearly equals, the low, close equals, or nearly equals, the high, for a bullish marubozu, and the reverse for a bearish one. On EURUSD, a bullish marubozu running from 1.0820 to 1.0865 with only a pip or two of wick on either end tells you sellers never mounted a real defense anywhere in that 45 pip stretch. That's a different animal from a candle with the same body that also carries a 15 pip lower wick, meaning sellers did push back before losing.
Reading the context: continuation or climax
A marubozu early in a fresh move, breaking out of a range or kicking off a new trend, usually means what it looks like: strong, one-sided conviction that tends to see follow-through over the next few candles. Gold breaking out of a two-week range with a $28 bullish marubozu is a believable start to a bigger move. A marubozu appearing after an already extended run, the fifth or sixth strong green candle in a row on a stock index, deserves more suspicion: that kind of one-directional conviction late in a move is a classic climax signature, the last surge of buyers piling in right before the move runs out of new participants to convert.
What follow-through actually looks like
The honest way to read a marubozu is to watch the very next candle rather than assume anything. Genuine continuation usually shows up as another strong-bodied candle in the same direction, or at minimum a shallow pullback that holds well inside the marubozu's range. A climax typically shows up as an immediate stall: a small-bodied candle, a doji, or an inside bar right after the big move, the market signaling it just spent its momentum rather than confirming it. The marubozu itself doesn't tell you which outcome is coming. The candle right after it usually does.
Trading around a marubozu without chasing it
Chasing a marubozu at its close is expensive: you're buying, or selling, at the exact extreme the candle already traveled to, with the worst risk-to-reward of the whole move. A more disciplined approach waits for the pullback that follows, entering on a shallow retracement that holds inside the marubozu's range, with the stop beyond that range's edge. On a $10,000 account, a Nasdaq marubozu with a 40 point pullback entry and a 60 point stop back beyond the range, at $1 per point per contract, sizes to roughly 1 contract under the 1% rule, a small, patient way to participate in a move you didn't chase at its worst price.
