Three Outside Up Pattern: How to Read and Trade This Reversal

The three outside up pattern is a three-candle bullish reversal setup: a red candle, a bigger green candle that swallows it, and a third green candle that closes higher still. On paper it looks like a bullish engulfing with an extra day bolted on. In practice, that extra day is the whole point. It is the market telling you whether the engulfing candle was a one-session flinch or the start of real buying.

We have covered the two-candle engulfing pattern and its quieter cousin, the three inside up pattern, before. This piece sits between them. We’ll go through the exact rules, what each candle says about buyers and sellers, a worked example with round numbers, the mistakes we see most often, and how to frame a trade around it without pretending a candlestick can predict the future.

What the three outside up pattern looks like

Investopedia’s definition lists four conditions. Put plainly:

1. There is a downtrend. The stock has been falling before the pattern shows up.
2. Candle 1 is bearish. It closes below where it opened, so it’s a red (or black) candle.
3. Candle 2 is bullish with a long real body that fully contains candle 1. This is the engulfing day.
4. Candle 3 is bullish and closes above candle 2’s close. This is the confirmation day.

That’s it. No volume rule is built into the definition, no minimum percentage move, no requirement that candle 3 gaps up. Those things can make the signal stronger, and we’ll come to them, but they are not what makes the pattern a three outside up.

The mirror image is the three outside down: an uptrend, a green first candle, a long red second candle that engulfs it, and a third red candle closing below the second. Everything in this article applies to it in reverse.

How it differs from the three inside up

People mix these two up all the time, so it’s worth being blunt. In a three outside up, the second candle is bigger than the first and wraps around it. In a three inside up, the second candle is smaller and sits inside the first, which is a harami. “Outside” means the second candle reaches outside the first. “Inside” means it stays within it. The outside version starts with a more aggressive show of buying, because the bulls didn’t just stop the fall, they erased the whole previous session.

Reading the three candles: who is winning, day by day

Candlesticks are a record of a fight. Investopedia describes the psychology roughly like this, and it’s a useful way to think about any reversal pattern.

Day 1, sellers still in charge. The stock closes below its open, carrying on the existing downtrend. Bears feel confident. Anyone who bought on the way down is nervous.

Day 2, the surprise. The stock opens lower, so at first it looks like more of the same. Then buyers step in and push it back up through the opening price and beyond, above the first candle’s range. The candle closes green with a long body. For short sellers, this is the moment to book profits or tighten stops, because a session that opened weak and closed strong is a warning.

Day 3, follow-through. The stock keeps rising and closes above day 2’s close. Investopedia frames this third candle as the point where buying signals get confirmed by a new high. It turns a single good day into two.

The engulfing candle tells you buyers showed up. The third candle tells you they came back the next morning. Only the second fact is worth trading.

That last line is our take, but it lines up with how StockCharts’ ChartSchool guide to bullish reversal patterns treats engulfing setups. It says most bullish reversal patterns need confirmation, and that without it they should be seen as neutral, at best marking a possible support level. A three outside up simply has that confirmation baked in as candle 3.

A worked example with round numbers

Let’s walk through a made-up case. The stock, the prices and the dates below are hypothetical, chosen to make the arithmetic easy. They are not real market data.

Say an NSE-listed stock, call it ABC Ltd, has slid from ₹600 to around ₹520 over three weeks. It is trading below its 20-day exponential moving average, and each bounce has stalled lower than the last. That’s our downtrend.

Now check the rules one by one.

• Downtrend: yes, about ₹80 lower over three weeks and below the 20-day EMA in our example.
• Candle 1 bearish: it opened at ₹526 and closed at ₹518, so the real body runs from ₹518 to ₹526.
• Candle 2 engulfs candle 1: its body runs from ₹514 (open) to ₹532 (close). Since ₹514 is below ₹518 and ₹532 is above ₹526, it fully contains day 1’s body. Its range of ₹512 to ₹534 also covers day 1’s high and low, which is the stricter, “ideal” version.
• Candle 3 closes higher: ₹541 is above day 2’s close of ₹532. Pattern complete.

A bit of arithmetic helps here. Day 2’s body is ₹18 (532 minus 514). Day 1’s body is ₹8 (526 minus 518). So the engulfing body is more than twice the size of the candle it swallowed. Day 3 adds another ₹9 on the close, a gain of about 1.7% on day 2’s close (9 divided by 532). Nothing dramatic, but it’s a higher close and a higher high, which is what we wanted.

Framing the trade

Here’s one common, simple way to frame it. It’s an illustration of the mechanics, not a recommendation.

• Entry: near day 3’s close, so ₹541, or on a move above day 3’s high of ₹543 the next session for those who want extra proof.
• Stop-loss: below the pattern’s low. The lowest point across the three candles is day 2’s low of ₹512, so a stop at, say, ₹509 gives a little room.
• Risk per share: ₹541 minus ₹509 is ₹32.
• Position size: if you’re willing to lose ₹4,000 on the idea, 4,000 divided by 32 is 125 shares.
• First target: the nearest resistance, perhaps the last swing high or the 20-day EMA. If that sits around ₹590, the reward is ₹49 a share against ₹32 of risk, roughly 1.5 to 1.

Notice what drives the numbers. A wide engulfing candle makes the stop further away and the position smaller. That’s not a flaw. It’s the pattern telling you how much the stock has been swinging, and your size should respect it.

What makes a three outside up more convincing

The basic definition is loose, so traders layer on filters. These are the ones we think matter most.

1. A real downtrend, defined in advance

StockCharts makes a point that sounds obvious but gets ignored: a bullish reversal needs an existing downtrend to reverse. A bullish engulfing at new highs, it notes, is better read as continuation than reversal. It suggests a few ways to define a downtrend, such as the stock trading below its 20-day EMA, each reaction peak and trough being lower than the last, or price sitting below a falling trend line. Pick one rule and stick to it, so you aren’t deciding after the fact that a sideways drift “counts”.

2. Location

A three outside up that forms at a known support zone, an old breakout level or a round number the stock has respected before carries more weight than one floating in empty space. Our technical analysis guide for Indian stocks covers how to mark those zones.

3. Size of the engulfing body

StockCharts says the first candle in an engulfing setup shouldn’t be a doji, since a tiny body is easy to engulf, and that the bigger the second, white candle is, the more bullish it is. Ideally, though not necessarily, the second body also engulfs the first candle’s shadows. Our ABC example met that stricter test.

4. Volume

It isn’t part of the formal definition, but rising volume on day 2 and day 3 suggests more participants backing the move. Thin volume on a holiday-shortened week deserves more scepticism. We go deeper in our piece on volume confirmation in trading.

5. Timing of the follow-through

StockCharts notes that candlestick patterns are short-term and usually effective for only one or two weeks, and that bullish confirmation should come within one to three days of the pattern. If the stock goes nowhere for two weeks after your three outside up, the signal has probably expired.

A candlestick pattern has a shelf life. If the move hasn’t started within a few sessions, stop waiting for it.

Common mistakes with the three outside up pattern

Calling it in a range. A stock bouncing between ₹500 and ₹540 will throw up engulfing candles every other week. Without a prior downtrend there’s nothing to reverse.

Ignoring the gap. On Indian stocks, overnight news (results, block deals, global cues) often makes candle 2 open far below candle 1. That’s fine and even typical, but a huge gap-down-then-rally day can also mean the stock is simply volatile around an event. Know why the candle happened.

Counting a tiny third candle as strong confirmation. A close one rupee above day 2 technically satisfies the rule. It doesn’t show much conviction. Some traders want candle 3 to close above day 2’s high, not just its close. That’s a reasonable, stricter filter.

Putting the stop too tight. Placing it just under day 3’s low feels efficient, but the natural invalidation point is the pattern’s low. If the stock falls back below the engulfing candle’s low, the bulls’ big day has been wiped out.

Trading it alone. Investopedia is clear that traders should look for confirmation from other indicators. RSI turning up from oversold, a moving average flattening out, or a bullish divergence all add context. A lone three-candle sequence is a prompt to look closer, not a reason to buy.

Using it on daily vs intraday charts

The pattern can appear on any timeframe. On a daily chart each candle is a full session, which tends to filter out noise. On a 5-minute or 15-minute chart you’ll see dozens of three outside up shapes in a week, and many are just random wiggles. If you trade intraday, we’d suggest checking that the higher timeframe is at least not fighting you. A bullish three outside up on a 15-minute chart while the daily trend is falling hard is a counter-trend scalp, and should be sized like one.

Weekly charts are a different matter. A weekly three outside up takes three weeks to form, so it’s slower, but it represents a lot more trading activity behind each candle. Positional traders often like these for that reason, while accepting that the stop-loss will be wider.

A quick checklist before you act

• Was there a clear downtrend by my own pre-set rule?
• Did candle 2’s body fully cover candle 1’s body?
• Did candle 3 close above candle 2’s close?
• Is it near support, and is there room before the next resistance?
• Did volume pick up on days 2 and 3?
• Does at least one other indicator agree?
• Is my stop below the pattern’s low, and is my position sized to that distance?

If you can tick most of those, the three outside up is doing its job: flagging a spot where sellers may be losing their grip. If you can tick only the shape and nothing else, it’s just three candles.

The bottom line

The three outside up is one of the easier reversal patterns to spot, and its built-in confirmation day makes it more trustworthy than a bare engulfing candle. But it’s still a short-term signal with a short shelf life. Use it where a downtrend is obvious, put your stop under the pattern, size your position off that stop, and let other evidence make the case alongside it.
