The three inside up candlestick pattern is a three-candle bullish reversal pattern that forms at the end of a downtrend. The first two candles form a Bullish Harami, and the third candle closes higher to confirm that buyers have taken control.
It serves as an early warning that the downtrend may be ending and an uptrend may be starting. The pattern is also written as 3 inside up, and it works the same way on stock, forex and commodity charts.
What Is the Three Inside Up Candlestick Pattern?
The three inside up pattern needs an existing downtrend and three candles in a fixed order. Each candle has one rule to meet, and the pattern is only complete when the third candle closes.
The first two candles on their own form a Bullish Harami, where the second candle’s body is engulfed by the first candle’s body. Gregory Morris introduced the three inside up as an extension of that pattern, with the third candle added to confirm it.
The second candle needs a visible body, so a doji does not count. On most charts the first candle is red or black, and the second and third candles are green or white.
A first candle counts as long when its body is clearly larger than the average body of the recent candles on the same chart.
What Does the Three Inside Up Pattern Mean in Technical Analysis?
Each candle in the pattern shows price action changes in who controls the price trend. So, if you read them in order, you’ll notice that the three candles move from sellers in control to buyers in control.
The first candle is a long bearish candle, so sellers still control price and the downtrend looks intact.
The second candle opens inside the first candle’s body and closes higher. Selling momentum has slowed and buyers have started to push back, although they are not in control yet.
The third candle closes above the second candle’s close, which shows buyers now have control. Traders who were short often close their positions here, and that buying adds to the push higher.
Taken together, the three inside up pattern signals a possible bullish reversal. It warns that the downtrend may be over, but the uptrend still has to follow through.
How Reliable Is the Three Inside Up Candlestick?
span id: how-reliable-is-the-three-inside-up-candlestick
The three inside up pattern is common. A signal that appears often also fails often, so each one needs to be judged before it is traded.
How Often Does the Three Inside Up Pattern Appear?
The pattern shows up regularly on stock, forex and commodity charts, on every timeframe. Many of those appear during weak downtrends or sideways ranges, where there is little selling to reverse in the first place.
The more often you see it, the more selective you need to be about which ones to act on.
How Accurate Is the Three Inside Up Pattern?
The three inside up pattern is unreliable on its own. Results change with the instrument, the timeframe and the strength of the downtrend before it, and many signals fail or lead to only a small move higher.
This is why traders wait for confirmation and use a stop loss on every trade. The next section covers what separates the stronger signals from the weak ones.
What Makes a Three Inside Up Signal Stronger? Confirmation Signals.
Some signals makes the three inside up candlestick pattern much more reliable. These are the signals that experiences traders check before acting on one.
It forms at a support level. The signal is stronger when the pattern appears at a known support level, because buyers already have a reason to defend that price.
The third candle is large. A third candle with a large body shows stronger buying than one that barely closes above the second candle.
The third candle closes above the first candle’s open. The standard rule only needs a close above the second candle’s close. Many traders use a stricter filter that needs a close above the first candle’s open, which means buyers took back the whole first candle body.
There is a gap before the third candle. A gap up between the second and third candles shows strong buying. Gaps are common on stock charts but rare on 24-hour markets such as forex and gold, so on those charts judge strength by the third candle’s body size and where it closes.
Volume rises on the third candle. High volume on the third candle shows more traders are buying.
A clear downtrend comes first. The pattern needs a downtrend to reverse. After a few flat candles, it has little to signal.
How to Trade the Three Inside Up Candlestick Pattern
The steps below cover a long trade on the three inside up pattern, from spotting the downtrend to placing the stop loss.
Find the downtrend. Check that price has been making lower highs and lower lows before the pattern appears.
Check the three candles. The first candle is long and bearish, the second candle’s body sits inside the first body, and the third candle closes above the second candle’s close.
Wait for the third candle to close. The pattern is not complete until then. A third candle that looks strong before it closes can still fade.
Look for extra confirmation. Some traders also want a breakout above a trendline or the nearest resistance level before they buy.
Enter the long trade. Buy at the third candle’s close or at the open of the next candle.
Place the stop loss. Put it below the lowest low of the pattern. If price falls back under that low, the bullish reversal has failed.
What Does a Three Inside Up Pattern Trade Look Like on XAU/USD?
XAU/USD printed a three inside up pattern on the weekly chart in August 2025, at the end of a short downtrend.
Image: XAU/USD weekly chart, zoomed in on the three inside up pattern, August 2025
First candle: the week of August 11 opened at 3,394 and closed at 3,337, with a low of 3,330. A long bearish candle.
Second candle: the week of August 18 opened at 3,333 and closed at 3,371, with a low of 3,311. A smaller bullish candle that closed back inside the first candle’s body.
Third candle: the week of August 25 closed at 3,448, above the second candle’s close of 3,371 and above the first candle’s open of 3,394. The pattern meets the stricter rule as well.
The entry is at the third candle’s close of 3,448. The stop loss goes below the second candle’s low of 3,311, which is the lowest point of the pattern, so the risk on the trade is 137 points.
In the weeks that followed, XAU/USD kept rising and moved above 4,000 in October 2025.
What Are the Advantages and Disadvantages of the Three Inside Up Pattern?
The three inside up pattern is easy to learn and has confirmation built in. The cost is a later entry, because traders have to wait for the third candle to close.
Advantages of the Three Inside Up Pattern
Clear rules. Each of the three candles has one condition, so the pattern is easy to spot on any chart.
Confirmation is built in. The third candle confirms the Bullish Harami, so you are not guessing whether buyers have followed through.
It shows how strong the bullish reversal is. The size of the third candle and where it closes show how strongly buyers stepped in.
Disadvantages of the Three Inside Up Pattern
Late entry. By the third candle’s close, price has already moved up from the low, so the stop loss is wider and less of the move is left.
Many weak signals. The pattern appears often, and a large share of those form in weak downtrends or ranges and go nowhere.
It can fail in a strong downtrend. When sellers are still strong, the third candle can be a short bounce before price falls again.
It needs confirmation. On its own the pattern is unreliable, so it works best alongside support levels, trendlines and volume.
The pattern only counts after a downtrend. The same shape inside an uptrend is not a three inside up, and it is not a sell signal.
Three Inside Up vs Three Inside Down: What Is the Difference?
The three inside down is the opposite of the three inside up. It has the same structure in reverse and signals a possible bearish reversal at the end of an uptrend.
These patterns, three inside up and three inside down, are opposite versions of the same logic, one for bullish reversal and another for bearish reversal. Hence, when you learn about one, you will understand how the opposite one works as well.
How Is the Three Inside Up Different From the Bullish Harami and Morning Star?
The Bullish Harami, the three outside up and the morning star can all mark the end of a downtrend, just like the three inside up. The difference is in the candle rules.
The Bullish Harami causes the most confusion, since it is the first two candles of the three inside up. The third candle is what separates them, and it is why many traders wait for the three inside up before acting.
FAQs
Is the three inside up pattern bullish or bearish?
The three inside up pattern is bullish. It forms after a downtrend and signals a possible bullish reversal.
Can the second candle of a three inside up be a doji?
No. The second candle needs a bullish body that sits inside the first candle’s body, and a doji has almost no body, so it does not meet the rule.
Which timeframe works best for the three inside up pattern?
No single timeframe is best. The rules are the same on every chart, so test the pattern on the timeframes and instruments you trade before relying on it.
