Triple Bottom — Trading the Third Bounce Off Support

In our article on the triple top, we debunked the confirmation myth: a third test of resistance statistically WEAKENS the short signal. Logic would suggest the mirror-image triple bottom faces the same fate. And here's a surprise — one of the more interesting ones in Bulkowski's entire catalog: the triple bottom works. Not just "a bit better" — it plays in a completely different league.

Numbers on the table: a failure rate of 13% (versus 25% for its twin), an average rise of 46% (versus a 14% decline), a measure-rule target hit 74% of the time (versus 49%), and a ranking of 12 out of 39 bullish patterns (versus 24/36). The same geometry, flipped upside down — and a chasm in results. This article shows how to trade a pattern that has earned this asymmetry, and explains where the asymmetry comes from.

How to Recognize a Triple Bottom

Bulkowski's identification criteria:

1. A downtrend before the pattern — but one that, after the first low forms, doesn't make new lows. Short- and medium-term declines (up to about 6 months) leading into the pattern tend to work best.
2. Three clear, similar-looking troughs at a similar price. Small differences in height are allowed — chart scale can be misleading, and a low that looks "clearly higher" by eye can be a fraction of a percent off from the others.
3. Volume is usually highest at the first low and fades across the pattern (61% of cases), though it can spike locally under each trough.
4. Confirmation: a close ABOVE the highest peak between the lows. A hard requirement — and more often unmet than you'd think: triple bottoms are rare (three troughs rarely line up "like soldiers in a row"), and price often drops away without ever confirming the setup.

Distinctions: a middle low that's clearly LOWER than the others is an inverse head and shoulders — a close relative with similarly good statistics; lows sitting on one line with the peaks between them also on one line is a rectangle; and an ascending broadening formation can imitate a triple bottom, so check whether the peaks between the lows are rising or standing still.

What the Numbers Say (Bulkowski, Encyclopedia of Chart Patterns)

The scorecard for confirmed triple bottoms in a bull market (over 2,500 "perfect trades" — results from breakout to extreme, so the upper bound of what the pattern can deliver):

Interpretation. Only one in eight confirmed patterns fails to deliver a 5% rise — a result from the top shelf of the catalog. The average rise of 46% puts the triple bottom in the neighborhood of the best reversal patterns (the inverse H&S: 45% with 11% failures — practically a family tie). The measure-rule target is reached by nearly three-quarters of cases, so — rare for this catalog — projecting the pattern's height genuinely tends to be realistic. The one blemish: a throwback in 65% of cases, meaning two-thirds of breakouts first return to the line, and throwbacks statistically drag down the pattern's subsequent performance.

It's also worth knowing what happens when the pattern fails. 23% of triple bottoms bust — price rises less than 10% after confirmation, reverses, and closes below the pattern's low. Single busts later decline an average of 23%, and the average across all busted patterns is -14%. Bulkowski himself downplays trading busted patterns in a bull market ("what's the point?") — they make more sense in a bear market, where they lose an average of 20-27%. For a long holder, the lesson is simpler: a busted low isn't "a chance to average down," it's a definitive invalidation.

The standard caveat: US stocks, daily timeframe, bull market, idealized trades. A bull market in stocks inflates the numbers for bullish patterns — part of the triple bottom's edge over the triple top comes from exactly that. Nobody has measured these distributions to this standard on crypto or forex.

How to Trade a Triple Bottom

Base entry: after confirmation. Buy on a close above the pattern's highest peak. The entry price can end up far from the lows (these patterns can be tall), but before confirmation the setup too often doesn't even materialize — patience is baked directly into the statistics.

Early entries (for those comfortable with the extra risk), both from Bulkowski's playbook: (1) a trendline through the peaks — if the bounce between lows 1-2 was higher than between 2-3, draw a descending line through the peaks and buy its break; (2) a shelf — when the third low builds a flat base, buy the breakout above it. Both tactics get you a better price at the cost of trading ahead of full confirmation.

Target. Pattern height (highest peak minus lowest low) × 74%, added to the breakout price. Example: lows at 100, pattern peak at 112 → height 12 → target about 120.9. "Big W"-style variants (a steep, fast decline into the pattern with no consolidation along the way) tend to run all the way back toward where the decline started.

Stop and throwback. Stop classically below the lowest low; with tall patterns, a compromise is a stop below the throwback low. Since 65% of breakouts return to the line, a calmer entry is often the throwback itself — buying as the pullback fades and volume on the retracement dries up.

Quality filters from the measurements: a third low ABOVE the second means better results (demand stepping in progressively higher); avoid patterns after a long, stretched-out uptrend (the breakout tends to disappoint) and setups sitting just under a clear resistance peak (rallies tend to stall there); be cautious with patterns after a downside gap on bad news (the market often comes back to punish it) and after candles with supply spikes right before the breakout.

The Asymmetry: Why the Third Test Works at the Bottom but Not at the Top

The clash between twins — 13% vs. 25% failures, +46% vs. -14% reach — is a bigger lesson than either pattern alone. Where does the gap come from?

First, a tailwind. The measurements come mostly from a bull market: the bullish pattern trades with the long-term drift of stocks upward, the bearish one against it. That explains a meaningful chunk of the difference, and it's fair to say so. But not all of it — double bottoms versus double tops differ far less dramatically.

Second, the psychology of a bottom and a top isn't a mirror image. Bottoms form on fear, which exhausts supply violently and definitively — whoever needed to sell in panic already has, and a third test on fading volume is a stamp of absorption (exactly the process Wyckoff's accumulation schematic describes: three support tests are the textbook ST inside an accumulation range). Tops form on greed, which fades slowly — demand doesn't vanish in a single climax, it leaks out over a longer stretch, which is why topping patterns fall apart and fail more often.

Third, selection by rarity. A triple bottom requires confirmation with a close above the whole pattern, and setups that don't reach that bar simply never enter the statistics as triple bottoms — only the specimens where demand genuinely finished the job survive. That inflates the quality of the sample, but from a trader's perspective it works like a built-in filter: the confirmation requirement screens out the weak cases for you.

The no-hype conclusion, the same as with the triple top, just from the other side: mirrored geometry is not mirrored statistics. You can't judge patterns as pairs "because they look the same" — each direction needs its own measurement. Here the measurement is clear: a third bounce off support, confirmed by a breakout, ranks among the more solid long plays in the catalog. A third rejection from resistance ranks among the weakest shorts. The same number of tests, two different worlds.

FAQ

When is a triple bottom confirmed? On a close above the highest peak between the lows. Without that, the setup often never even forms — triple bottoms are rare, and price can walk away downward from what looks like a "finished" pattern. Buying the third bounce alone is trading ahead of the signal.

Is a triple bottom better than a triple top? In Bulkowski's measurements, unambiguously: 13% vs. 25% failures, +46% vs. -14% average move, rank 12/39 vs. 24/36. Part of the gap comes from the stock market's bullish bias; the rest comes from psychology — panic exhausts supply faster than greed exhausts demand.

Where's the stop loss? Below the lowest of the three lows — a close beneath it breaks the pattern (a busted triple bottom, after which price drops an average of several tens of percent, so there's nothing left to defend). With tall patterns, an alternative is a stop below the throwback low, which arrives in 65% of cases anyway.
