Three Inside Up and Down

The three inside up and down is a three-candle confirmation pattern where a harami (an inside or contained candle) is validated by a third candle that closes further in the direction the harami signalled. It transforms a two-candle reversal setup into a more reliable three-candle continuation.

The structure: harami plus confirmation

The pattern has three distinct parts. The first candle is long and establishes direction—a strong down candle in the bullish setup, or a strong up candle in the bearish setup. The second candle is smaller and its entire range sits within the first candle’s open and close; this is the defining feature of a harami, and it typically shows reduced momentum or indecision. The third candle then closes above (in the bullish case) or below (in the bearish case) the second candle’s close, signalling that buying or selling has resumed.

The harami on its own is a mild reversal signal—it suggests momentum is fading and a turn may come. Adding the third candle ups the ante: it proves that the indecision stage has resolved in the direction the harami hinted. That’s why “inside up and down” is less a reversal pattern than a confirmation of reversal intent.

Why the pattern carries weight

A long first candle shows conviction in one direction. The tiny second candle, nestled inside the first, creates visual contrast and signals that the prior direction has lost its grip. Crucially, the pattern acknowledges that many traders who see a harami don’t act immediately—they wait for confirmation. The third candle gives it to them. By closing beyond the harami’s close, it signals that the sellers or buyers (whichever were outnumbered on day two) have now regained control.

This is a continuation pattern because it typically occurs after an established trend has already reversed or is about to. It is less about predicting an entirely new move and more about saying, “The old trend has stalled; the new move is now resuming.” The three-candle sequence is also psychologically coherent: strong directional move, loss of confidence, renewed conviction.

Spotting it in different contexts

In an uptrend that is starting to roll over, you might see a strong down candle (the first), followed by a small up candle (the harami—hope from the bulls), followed by another down candle that closes lower. That’s the bearish version: sellers have taken control, and the move down is likely to extend.

The bullish mirror applies after a downtrend starts to recover: a strong up candle, a small down candle, then a strong up candle that closes higher. Sellers were unable to hold the rally, and the recovery continues.

The pattern is cleaner when the first candle is notably longer than the second; a near-equal pair is less convincing. Similarly, the third candle should close decisively past the second, not just barely edge out. A close that merely equals the second candle’s close is ambiguous—you want clear evidence of resumed directional pressure.

When it works, and when it doesn’t

This pattern shines in markets with defined trends, where a brief loss of momentum (the harami) followed by renewed directional push (the third candle) tends to extend the move. In choppy or sideways markets, the pattern is less reliable because the harami may represent genuine uncertainty rather than a pause between pushes in the same direction.

The pattern also depends on context. A three inside up in the middle of a strong uptrend is a bullish continuation signal. The same pattern at the very top of a market, after a parabolic run, is far less trustworthy—it may be a false reassurance before a top forms. Pairing the pattern with volume, support and resistance, or moving averages increases confidence.

One common pitfall is mistaking a three inside for a harami star, which has a gap between the first and second candles. The three inside up and down has the second candle completely contained within the first—no gap. That containment is essential to the pattern’s logic.

Using it in strategy

Many traders treat the pattern as a setup for entry in the direction of the third candle, with a stop below (for bullish) or above (for bearish) the second candle. The stop placement is logical: if the pattern fails and the second candle’s extreme is breached, the signal is invalidated.

Position sizing matters. A three inside up and down is not a high-probability pattern on its own; it works best as part of a broader systematic approach. Combining it with other patterns—such as confirmation from RSI crossing above 50 on the bullish setup, or a break above a trendline—can improve results.

The time frame matters too. The pattern on a daily chart has more weight than the same shape on a five-minute intraday chart, where noise is higher and patterns form and vanish without meaningful follow-through. Swing traders and position traders find it more useful than day traders.
