Three Outside Up — Bullish Engulfing With Confirmation

On paper, Three Outside Up looks like an upgraded version of one of the most famous patterns in the world: take a bullish engulfing, add a confirming candle, and the reversal rate climbs from 63% to 75%. Sounds like a free lunch. The data says otherwise: the lunch isn't free — you pay for it with a worse entry price, weak short-term results, and a target that's delivered less than half the time. Here's the full bill.

What the Pattern Looks Like

Three Outside Up is a three-candle bullish reversal pattern — a bullish engulfing plus confirmation, per Morris's definition, the pattern's creator. The conditions:

• Trend before the pattern: downtrend. This is a reversal pattern — it needs something to reverse.
• Candle 1: bearish (black). Continuation of the downward move.
• Candle 2: bullish (white), opening below candle 1's body and closing above it. A full body engulfing — demand recovers the entire prior day with room to spare in a single candle.
• Candle 3: closes higher than candle 2. Confirmation — demand holds control for a second consecutive day.

The story: supply is in control, then demand suddenly seizes the session so decisively it swallows the entire previous move, and the next day it confirms that again. The engulfing says "something changed"; the third candle says "that wasn't an accident."

A note for crypto: the classic definition assumes candle 2 opens below the prior candle's body — on a 24/7 market, an open always equals the previous close, so a literal "gap-down open" doesn't happen. In practice, on BTC/ETH, traders use body-engulfs-body (candle 2's close above candle 1's open). That's a reasonable adaptation, but remember the statistics were measured on the strict version.

What the Numbers Show

Results from Bulkowski's tests (~4.7 million daily candles, US stocks):

• Bullish reversal: 75% of cases. A very good result — well above the threshold of respectability. For comparison, a plain bullish engulfing scores 63%.
• Overall performance rank: 34/103. High — the trend following a breakout, as the study's author puts it, "has legs."
• Frequency: 24/103. A common pattern — you'll find it regularly, which makes it a practical tool.
• Measure-rule target: best 47% (bull market, upside breakout). This is an important number: even in the best-case variant, price delivered the pattern's height less than half the time. Bulkowski warns explicitly — don't expect a straight-line move.
• Best average 10-day move: -7.14% — following a downside breakout in a bear market, ranking 7th for 10-day performance. That same recurring theme: the pattern showed its strongest measured moves precisely when it failed as a bullish signal in an ongoing bear market.

Two warnings from the data are easy to miss. First, short holding periods after an upside breakout perform notably poorly — if you're planning a 10-day trade, the data says this isn't the pattern for it. Second, over a longer horizon, avoid downside breakouts in a bull market — that's where the results were worst.

It's worth comparing this pattern to its closer and more distant relatives. A plain bullish engulfing: 63% reversals, rank 84/103 — confirmation lifts both metrics at once here, which is by no means the rule (in the mirror-image Three Outside Down, confirmation actually lowers the reversal rate). Meanwhile Three Inside Up — a harami with confirmation — scores 65% and rank 20: it reverses less often, but the post-breakout move tends to be better. There are no free candles: every setup has its own trade-off profile.

The standard caveat: data from US stocks, daily timeframe, "hundreds of perfect trades" under laboratory conditions. Crypto has different volatility and structure — carry over the logic, not the percentages.

How to Trade It

Scenario 1 — the end of a pullback within an uptrend (the data-recommended setup). The best version: an overarching uptrend, a downward correction, and Three Outside Up at its bottom. An upside breakout then means a return to the existing trend — "and off she goes," as Bulkowski writes. Enter on a close above the pattern's high, stop below its low, with a horizon longer than a week.

Scenario 2 — a bottom reversal, with managed expectations. The pattern also works after a longer decline (75% is 75%), but keep two things in mind: you're entering after three candles of upward movement, often into short-term overbought conditions, and the target is delivered in under half of all cases. Consider entering on a shallow pullback after the breakout instead of chasing the third candle — you improve your price and tighten your stop.

Scenario 3 — a broken pattern in a bear market. A close below the pattern's low in a bear market is statistically the strongest measured variant of this pattern (averaging -7.14% over 10 days). A bullish pattern that broke in a bearish environment is a signal of bear-market continuation — not a "cheap" long opportunity.

How NOT to play it. Don't enter on candle 2 telling yourself "it's already an engulfing" — if you want to trade the plain engulfing, trade it deliberately (63%), not as half of a better pattern. Don't play this setup for quick trades — 10-day results after an upside breakout are weak per the data. And don't set a target mechanically at the pattern's height without a plan B: in most cases price pulls back at least once along the way.

Stop loss and target. Stop below the pattern's low — and since engulfing-plus-confirmation can span a wide range, that stop can be far away. If the risk-reward doesn't work out, wait for a pullback or skip the trade. Target: resistance, the prior high, or the pattern's height projected from the breakout point — with partial profit-taking, since the full target lands less than half the time.

Myth vs. Measurement

Myth: "75% success means you can enter blind." Measurement: 75% refers to trend reversal, not to profit on your specific trade. The measure-rule target is achieved best in 47% of cases, and short-term results after an upside breakout are weak. Reversal isn't the same as a delivered target.

Myth: "Confirmation always pays off." Measurement: here it does — 63% → 75% — but at the cost of entering after two strong bullish candles and a wider stop. In the mirror-image Three Outside Down, confirmation actually lowers the reversal rate relative to the plain engulfing. Confirmation is always a trade-off: certainty for price.

Myth: "A bullish pattern can't be a signal for a decline." Measurement: the strongest average move after Three Outside Up was -7.14% following a broken pattern in a bear market. A downside breakout from a bullish setup carries information — ignore it and you give away your edge.

A Sample BTC Scenario

BTC is in a D1 uptrend, correcting for a week and a half back into the zone of a previous breakout. At the bottom of the pullback: a red candle, followed by a large green candle whose body fully engulfs the red one, and on the third day another higher close. Three Outside Up in a textbook context — the end of a pullback within an uptrend.

The plan: enter on a D1 close above the pattern's high, or — better for the math — on a shallow pullback into the area of candle 2's high. Stop below the pattern's low. First target at the high before the pullback, with partial profit-taking, the rest on a trailing stop, on a horizon of weeks rather than days. If instead of continuation you get a close below the pattern's low with a weak broader market — the long is off the table, and a short-side scenario comes back onto the table.

Quick checklist:

• Is there a downward move before the pattern (ideally: a pullback within an overarching uptrend)?
• Does candle 2's body fully engulf candle 1's body?
• Does candle 3 close higher than candle 2?
• Is your holding horizon longer than 10 days?
• Does a stop below the pattern's low still give a sensible risk-reward ratio?
• Do you have a plan ready for the pattern breaking (a close below the low) before entering?

Three Outside Up is one of those patterns that honestly earns its reputation: a high reversal rate, good performance, decent frequency. The data adds only three fine-print notes: not for quick trades, not without tolerance for pullbacks, and not without a plan for the pattern breaking. Accept those terms, and you get one of the more solid setups in the catalog.
