Three Inside Up
bullish reversal signal · 3 candles · reliability 4/5
A bullish harami confirmed by a third bullish candle, signaling a gradual reversal attempt after a downtrend.
The Three Inside Up pattern starts with a bullish harami and adds a confirming bullish candle. The first session is a large red candle showing seller control, followed by a small green body contained within the first body, which signals uncertainty. The third session prints a strong green candle that closes above the first candle’s body. Together, the three candles confirm a potential downtrend reversal; the harami alone is weak, while the third candle provides the confirmation.
What does it signal? Three Inside Up is a potential reversal signal at the end of a downtrend — sellers pushed price lower, but buyers turned it back up.
When is it reliable? It is more reliable at strong support, with above-average volume and another confirming green candle in the next period.
When to avoid it? Avoid it in sideways markets and on very short time frames such as 1-minute or 5-minute charts, where noise makes the signal less useful.
Anatomy and identification rules

- 3
Third candle: large green body that closes above the top of the first body
- 4

Identification rules
- Appears after a downtrend
- The first and second candles form a bullish harami structure
- The third candle closes above the upper level of the first candle’s body
- The third body is at least 1.5 times the size of the second body
- The full pattern carries more weight when volume increases
Pattern in chart context
What it says about the market
Context of appearance: This pattern appears near the end of a downtrend, often around an important support level. It is much more reliable than a standalone bullish harami.
Market psychology in three steps
- 1
The downtrend continues. Several candles show lower highs and lower lows. Sellers control the market, and sentiment remains negative.
- 2
Three Inside Up takes shape. Seller pressure fades and buyers return. Price is pulled back near the starting area, creating the possibility of a reversal.
- 3
Confirmation arrives. The next candle closes with a green body, ideally on higher volume. Sentiment has shifted, and a new uptrend may begin.
Same shape, opposite meaning
The Three Inside Up and the Three Inside Down look identical. The difference lies in context — mistake one for the other and you enter in the opposite direction. The candle shape alone is never enough: always read the trend first, then the pattern.
Most common mistakes
-
Ignoring context. Three Inside Up only has meaning near the end of a downtrend. In a sideways market or an uptrend, the same structure carries a different message, so the trend comes first.
-
Entering without confirmation. The pattern itself is not always an entry trigger. Waiting for the confirming green candle to close reduces false signals.
-
Using too short a time frame. On 5-minute candles, most reversal patterns are noise. Daily and 4-hour charts tend to produce cleaner signals.
-
Overlooking the multi-candle structure. Three Inside Up consists of three candles, and each one needs to meet the conditions. If only the final candle looks correct, the signal is flawed.
