The Failed Breakout Reversal: How to Trade Bull Traps and Bear Traps
In this article8 sections
Every other guide in this hub has covered how to confirm a breakout and avoid getting caught in a fakeout. This one covers the opposite skill: recognizing when a breakout has already failed, and trading the reversal that often follows — a reversal that long-running empirical research suggests can move harder than the original breakout ever would have.
The traders trapped by a failed breakout don't just disappear quietly. They're holding a losing position, and at some point most of them have to exit — buyers who bought a failed upside breakout eventually sell, short sellers who shorted a failed breakdown eventually cover. That forced unwinding is exactly what fuels the reversal this guide is built around.
What is a bull trap or bear trap? A bull trap is a false upside breakout that lures in buyers before reversing sharply lower. A bear trap is the mirror image — a false downside breakdown that lures in short sellers before reversing sharply higher. Trading the reversal means entering once the failure is confirmed, rather than trying to catch the original breakout at all.
"Busted Pattern" vs. an Ordinary Fakeout: Getting the Terms Right
"Bull trap" and "bear trap" are the common, descriptive names for this behavior, but chart-pattern researcher Thomas Bulkowski defined a more precise version worth knowing: a "busted" pattern is specifically one where price breaks out, moves no more than 10% in that direction, then reverses and breaks out the opposite side of the original pattern entirely. That last part matters — a busted pattern isn't just a rejection back to where it started; it's a full reversal that goes on to break the pattern's other boundary as well.
This is a meaningfully stricter definition than a simple failed breakout or fakeout, which might just mean price rejected the level and drifted back to the middle of the range without ever committing to the opposite direction. The setup in this guide is built around the fuller, confirmed reversal — not merely the failure of the first move.
The Research: Failures Are Common, and the Reversal Can Be the Stronger Trade
Bulkowski's own research found that busted patterns occur often enough to matter, and that the rate varies considerably by pattern type and direction. In one comparison of symmetrical triangles during bull markets, downward breakouts busted 48% of the time, while upward breakouts busted only 32% of the time — a substantial difference depending on which direction the original breakout occurred.
The more striking finding is about what happens after the bust. Bulkowski's stated conclusion, based on this research, is that the move following a busted pattern is often stronger than the move that would have followed a successful breakout in the original direction. The reasoning ties directly to the trapped-trader dynamic described earlier: a busted pattern leaves a specific, identifiable group of traders holding a losing position, and their eventual forced exit adds fuel to the reversal that a "clean" breakout, without that trapped population, simply doesn't have behind it.
This finding runs counter to how most traders instinctively think about a failed setup. A breakout that doesn't work is usually filed away as a loss to move past, not as the leading indicator of an even better trade in the opposite direction. Bulkowski's research reframes the failure itself as the actual signal — the setup isn't "the breakout didn't work, so ignore this stock," it's "the breakout didn't work, so watch closely for the reversal it's now more likely to produce."

The Invalidation Criteria row is the detail most likely to get skipped. A rejection back to the middle of a range is a common, unremarkable outcome that doesn't meet Bulkowski's stricter definition of a bust — treating every simple failure as a tradeable busted-pattern reversal, without waiting for the actual opposite-side breakout, misapplies the more specific and better-supported version of this setup.
A Walk-Through: A Bull Trap That Busts to the Downside
Picture a mid-cap stock — call it ABC, trading around $58 — that's formed a clear ascending triangle over several weeks, with resistance at $60. The stock closes at $60.80 on solid volume, confirming what looks like a standard breakout under the general checklist.
Over the next several sessions, instead of continuing higher, ABC stalls and drifts back down, closing below $60 again — the original breakout level — without ever having moved more than about 3% above it. That's the failed leg. Days later, the stock continues falling and closes below $55, the triangle's lower boundary from when it originally formed. That confirms the bust: a failed upside breakout that has now broken the opposite side of the same pattern.
The reversal entry triggers on that close below $55, with a stop placed just above $61 (the extreme of the original failed breakout). The triangle's height — roughly $6, from $54 to $60 — gets projected downward from the $55 breakout point, targeting around $49.
Now picture an alternate version: instead of closing below $55, ABC drifts down to $56.50 and stabilizes there, never actually breaking the triangle's lower boundary. That's an ordinary failed breakout, not a confirmed bust — the Invalidation Criteria apply, and this setup shouldn't be traded on the assumption that a full reversal is already underway.
Where the Busted Pattern Reversal Fails
The most common failure is trading a simple rejection as though it were a confirmed bust. Bulkowski's own definition requires the full opposite-side breakout, not just a retreat from the original level — a stock that fails an upside breakout and then simply chops sideways hasn't busted yet, and entering a reversal trade on that basis alone is trading a weaker, less-defined signal than the research actually supports.
It also fails when the original breakout was never well-confirmed in the first place. A busted pattern following a marginal, low-volume initial breakout carries less information about trapped traders than one following a genuinely convincing move on strong volume — there's simply a smaller population of committed traders to be forced out in the weaker case.
And it fails when position sizing doesn't account for the reversal's own volatility. A stock that's already made one sharp, unexpected move (the failed breakout) and is now making a second one (the bust) can be more volatile than a stock making a single clean move in one direction, which argues for the same careful, ATR-aware sizing used throughout the rest of this hub rather than assuming the reversal will behave predictably.
A subtler failure is entering too early, on the first sign that the original breakout is stalling, rather than waiting for the full opposite-side confirmation. A stalling breakout that hasn't yet closed back through its own level, let alone through the opposite boundary of the pattern, is still an unconfirmed situation — anticipating the bust before it's actually confirmed is the same mistake as anticipating any other unconfirmed breakout, just applied to the reversal instead of the original move.
Why the Direction of the Original Breakout Matters
Bulkowski's research found meaningfully different bust rates depending on whether the original breakout was upward or downward, and depending on the broader market environment at the time. This means a busted pattern isn't a single, uniform phenomenon — a downward breakout busting in a bull market (as in the symmetrical triangle example above, where 48% of downward breakouts busted) is a meaningfully more common occurrence than an upward breakout busting in the same environment.
The practical implication: a busted pattern occurring against the grain of the broader market environment — a downward break failing during a bull market, for instance — shouldn't be treated as an unusual, low-probability surprise. It's closer to the historically expected outcome under those specific conditions.
Where This Fits a Complete Trading Plan
This setup depends entirely on the general breakout vs. fakeout checklist having already been applied to identify a genuinely confirmed original breakout — without that first confirmation, there's no meaningful baseline against which to judge whether a subsequent bust has actually occurred. The retest strategy covered elsewhere in this hub is worth distinguishing from this one: a retest is a pullback that resumes the original direction, while a bust is a full reversal that abandons it entirely.
For the rest of the breakout and breakdown setups this guide complements, the Strategies Hub organizes the full library by market condition.
Frequently Asked Questions About Bull Traps and Bear Traps
What's the difference between a bull trap and an ordinary failed breakout?
An ordinary failed breakout might just mean price rejected the level and drifted back toward the middle of the range without committing to a full reversal. The stricter busted-pattern definition requires that fuller reversal, which is a meaningfully stronger and more specific signal.
Key Takeaway: Reserve the term "bust" for a full reversal through the opposite boundary, not just a simple rejection of the original breakout.
Why can a busted pattern's reversal move harder than the original breakout would have?
Bulkowski's own research on busted patterns concluded that the reversal move is often stronger than the move that would have followed a successful breakout in the original direction, which is consistent with this trapped-trader explanation.
Key Takeaway: The reversal's strength comes partly from forced exits by traders caught on the wrong side, not just from ordinary technical follow-through.
How common are busted patterns?
These aren't rare, tail-risk events — depending on the specific conditions, a meaningful share of breakouts can fail this way, which is part of why understanding how to trade the reversal is a genuinely useful skill rather than a niche edge case.
Key Takeaway: Expect bust rates to vary substantially depending on the specific pattern, breakout direction, and broader market environment rather than assuming a single fixed rate.
How is the profit target set on a busted pattern reversal?
This keeps the target grounded in the pattern's own established scale rather than an arbitrary number, and it's the same measure-rule approach Bulkowski's broader research uses for chart-pattern targets generally.
Key Takeaway: Use the original pattern's height, not the failed breakout's size, as the basis for the reversal's profit target.
Why does the quality of the original breakout matter for trading its eventual bust?
A marginal breakout that barely qualified under the standard confirmation checklist doesn't leave the same scale of trapped positioning behind when it fails, which weakens the trapped-trader logic that explains why busted-pattern reversals tend to be strong.
Key Takeaway: A bust following a genuinely convincing original breakout is a more informative signal than one following a marginal, weakly confirmed move.
What's the difference between a retest and a busted pattern?
Both involve price returning to the vicinity of the original breakout level, but they represent fundamentally different outcomes — one confirms the original move, the other reverses it completely. Confusing the two can lead to holding a position through what's actually a full reversal, on the mistaken assumption that it's merely a healthy retest.
Key Takeaway: A retest resumes the original direction; a bust replaces it entirely — check which one is actually occurring before assuming either.
Does market environment affect how often a breakout busts?
This means a bust occurring against the grain of the broader market — for instance, a downward break failing during a bull market — is closer to a historically expected outcome under those conditions than an unusual surprise.
Key Takeaway: Weigh the broader market environment when judging how likely a given breakout is to eventually bust.
Should every failed breakout be assumed to eventually bust and reverse?
Waiting for the specific opposite-side breakout, rather than assuming it will happen once the original move fails, is the discipline that separates this setup from simply guessing that every failed breakout must reverse hard.
Key Takeaway: Wait for the confirmed opposite-side breakout before treating a failure as a tradeable bust.
How should position sizing differ for a busted pattern reversal compared to an ordinary breakout?
The same ATR-based sizing discipline used for ordinary breakouts applies here, with extra attention paid to the fact that the instrument has already demonstrated it can move sharply and unexpectedly once this session or pattern.
Key Takeaway: Size the reversal trade with the instrument's demonstrated volatility in mind, not with the same assumptions used for a single, uncomplicated breakout.
Why do bull traps specifically catch so many traders off guard?
This is the same underlying issue covered in the general breakout confirmation checklist: an initial move can't be judged with certainty until it either continues or reverses, and a bull trap is simply the specific case where the reversal, rather than continuation, turns out to be what follows.
Key Takeaway: Recognize that a bull trap and a genuine breakout look identical at the outset — the distinguishing evidence only arrives afterward.
