Three Inside Down — Bearish Harami With Confirmation

Three Inside Down is the mirror image of Three Inside Up — and a good example of how a mirror can distort things on the market. The bullish variant reverses the trend 65% of the time with a rank of 20/103. The bearish variant? 60% and rank 56/103 — the middle of the table. Same logic, same three candles, a noticeably weaker result. On top of that, the data shows the best moves after this pattern actually went... up. Before you short a Three Inside Down, see what was actually measured.

What the Pattern Looks Like

Three Inside Down is a three-candle bearish reversal pattern — a bearish harami with a confirming candle, as Morris defined it. The conditions:

• Trend before the pattern: uptrend. The pattern is meant to reverse gains — three candles inside an ongoing decline is a completely different story.
• Candle 1: large and bullish (white). Demand is still dominant and looks strong.
• Candle 2: small and bearish (black), opening and closing inside candle 1's body. An inside candle — momentum stalls, the market hesitates. The tops or bottoms of the bodies may line up, but not both at once.
• Candle 3: closes below candle 2's close — color doesn't matter. This is the confirmation: supply has taken over.

The story: the market rises with momentum, indecision suddenly appears (harami), and the next day sellers close out the reversal with a lower close. Note an interesting detail in the definition — the third candle doesn't have to be red. What matters is the lower close, not the color of the body.

On crypto, the pattern occurs without issue — it doesn't require gaps, so a 24/7 market doesn't eliminate it. As always with inside-candle setups: candle 2's body must genuinely fit inside candle 1's body. An "almost inside" candle isn't a harami, and without a harami there's no Three Inside Down.

What the Numbers Show

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

• Bearish reversal: 60% of cases. Bulkowski himself is unenthusiastic about this: since 50% is random behavior, 60% doesn't inspire much confidence. The pattern works, but right at the edge of respectability.
• Overall performance rank: 56/103. Dead center of the table. The move following a breakout, as the study's author puts it, "won't take your breath away."
• Frequency: 33/103. The pattern is easy to find — that's actually a plus.
• Best average 10-day move: +4.93% — a gain, following an upside breakout in a bear market. Bulkowski considers moves of 6% or more "good," so even this pattern's best variant doesn't make that league.

Two things need to be said plainly here. First, the weakest scenario is a downside breakout in a bull market — exactly the one most traders want to play: shorting a bearish pattern during a rally. The data says: that's the worst possible configuration of this setup. Second, the pattern's best measured move (that +4.93%) came after its own failure — when price broke out to the upside. Sound familiar? It was identical for Three Inside Up, just in reverse. Confirmed inside-candle patterns "work" best precisely when they break.

It's also worth appreciating what confirmation actually does here: a bearish harami on its own didn't reverse the trend at all in testing (53% continuation of the uptrend — the signal worked opposite to theory). The third candle lifts the setup to 60% reversals. Still not a strong signal, but at least it works in the direction it claims to.

The standard caveat applies: data from US stocks, daily timeframe. Crypto is a different volatility regime and a 24/7 market — carry over the logic, not the percentages.

How to Trade It

Scenario 1 — a pullback within a downtrend (the only setup with a measured recommendation). Bulkowski points directly to this: the best version of Three Inside Down appears at the top of an upward correction within an overarching downtrend. The market falls, bounces up, the pattern prints at the top of the bounce — and a downside breakout means a return to the existing trend. Enter on a close below the pattern's low, stop above its high.

Scenario 2 — a defensive signal for a long position. If you're holding a long and Three Inside Down appears on the D1 after a clear rally, it's a sensible moment to tighten your stop or take partial profit. For a defensive decision, it's enough to know momentum has stalled and supply has taken two candles — you don't need to believe in a full reversal.

Scenario 3 — the pattern breaking. A close above the top of the setup (candle 1's high) invalidates the signal — and per the data, the best moves followed exactly these kinds of breaks. If the overarching trend is bullish, a broken Three Inside Down is an argument for returning to longs, not for stubbornly hunting a top.

How NOT to play it. Don't short a bull market just because you spotted these three candles — a downside breakout in a bull market is the worst measured variant. Don't enter on the third candle alone without a close below the pattern's low. And don't expect a big move: rank 56/103 means even a successful reversal tends to be shallow — the target needs to be close, and partial profit-taking is mandatory.

Stop loss and target. For a short: stop above the pattern's high, target at the nearest significant support. When entering on a pullback within a downtrend, the stop can go above the correction's high. Since moves after this pattern are statistically modest, a risk-reward ratio below 1.5:1 disqualifies the setup.

Myth vs. Measurement

Myth: "A confirmed bearish harami is a strong short signal." Measurement: 60% reversals with rank 56/103 makes this, at best, an adequate pattern. Shorting a bull market on this setup is the worst measured scenario, and the best moves followed a breakout... upward.

Myth: "Since the bullish variant works 65% of the time, the bearish variant works the same." Measurement: mirror-image patterns don't have mirror-image statistics. Three Inside Up: 65%, rank 20. Three Inside Down: 60%, rank 56. Equity markets have a long-term upward drift, and bearish patterns consistently suffer for it — worth remembering when carrying conclusions over to crypto too.

Myth: "The third candle has to be red, otherwise the pattern doesn't count." Measurement (or really, the study's definition): what matters is the lower close, color doesn't matter. Rejecting valid setups over body color is filtering out noise the definition never asked for.

A Sample BTC Scenario

BTC has been sliding in a downtrend on the D1 for several weeks. A bounce arrives — a few green candles push price up into a resistance zone and a previously broken moving average. At the top of the bounce, a large green candle prints, followed by a small red candle tucked inside its body, and on the third day the close comes in below the second candle's close. This is exactly the context the data flags as best: Three Inside Down at the top of a correction within a downtrend.

The plan: short entry on a D1 close below the pattern's low, stop above the bounce's high, target at the last local low — with partial profit-taking, since moves after this pattern tend to be shallow. The alternate case: if instead of a downside breakout price closes above the pattern's high, the short is off the plan — and if the broader market is bullish, a broken pattern becomes an argument for the long side.

Quick checklist:

• Is there a clear upward move before the pattern (ideally: a pullback within a downtrend)?
• Does candle 2's body (open and close) fit inside candle 1's body?
• Does candle 3 close below candle 2's close?
• Are you waiting for a close below the pattern's low before shorting?
• Are you avoiding shorting a strong bull market on this pattern alone?
• Is the target close and partial profit-taking planned (rank 56 = shallow moves)?

Three Inside Down teaches humility about symmetry: the same construction as its bullish twin, half the result. Played in the right context — as the end of a correction within a downtrend — it has a place in the toolkit. Played as a universal "top signal," it's exactly what the data showed it to be: a setup barely better than a coin flip.
