Short answer

A triple bottom is a bullish reversal pattern in which price falls to roughly the same support level three times, with two rallies in between, and then closes above the resistance those rallies created, called the neckline. Three failed attempts to break lower suggest selling pressure is running out, but the pattern only counts once the neckline breaks, ideally on rising volume.

Triple bottom pattern diagram.After a decline, price makes three lows at about the same level with two rebounds between them; the neckline is drawn at the lower rebound high, so the first rebound pokes above it. Price breaks above the neckline; the stop sits half the neckline-to-lows height below the neckline and the target one full height above the breakout.NecklineLow 1Low 2Low 3StopTargetBreakout
A triple bottom: three similar lows, a neckline at the lower of the two rebound highs, a long when price breaks above it, a stop half the pattern’s height below the neckline and a target one height above the entry.

What is a Triple Bottom?

A triple bottom forms when a falling market finds buyers at about the same price on three separate occasions. Each low is followed by a rally, and the highs of those rallies form a ceiling called the neckline. The pattern is complete only when price closes above that ceiling; until then it is a range with three similar lows, and the next test could just as easily break support.

The psychology is about repeated failure. The first low looks like an ordinary pause in a downtrend. The second, at the same level, is where a double bottom trader starts paying attention. The third test matters because sellers had yet another chance to push through support and could not: demand kept appearing at the same price. When the neckline finally gives way, traders who sold the range are caught on the wrong side, and buyers who waited for proof step in together, which is why the breakout can travel quickly. The bearish mirror image is the triple top.

Anatomy of the Triple Bottom

Each part of the formation has a job:

ComponentWhat it isWhat to look for
Prior declineThe downtrend that brings price to supportWithout it, there is nothing to reverse
First lowThe first test of supportOften comes on heavy selling
First rallyThe bounce off the first lowIts high is one neckline candidate
Second lowA retest near the first lowClose in price to the first
Second rallyThe next bounceIts high is the other neckline candidate
Third lowThe final testIdeally on lighter selling, and it holds
NecklineResistance across the rally highsThe level price must close above
HeightDistance from the lows to the necklineSets the measured move target

The lows rarely match to the tick, so treat them as a support zone rather than a single price. When the two rally highs differ, the neckline is a choice: a sloped line through both, the higher high (a later, more conservative trigger) or the lower high (an earlier one). PatternX uses the lower of the two.

How to identify a Triple Bottom

Run through this checklist before treating three lows as a triple bottom. It reflects general textbook practice; the numeric tolerances PatternX itself applies appear later, under detection.

  1. Find the prior decline. A reversal pattern needs a trend to reverse. Three equal lows inside a sideways market are usually just range support.
  2. Mark three distinct lows. Each should be a clear swing low, not three bars inside the same dip.
  3. Check that the lows are similar. They should be close enough that you would call them one support zone.
  4. Check the spacing. The lows need room between them for real rallies; three lows crammed into a handful of bars are noise.
  5. Measure both rallies. Each bounce should rise meaningfully off support. Tiny wiggles do not create a usable neckline.
  6. Draw the neckline before the breakout. Decide in advance which rally high defines it, so you are not redrawing it to fit the move.
  7. Compute the height from the average of the lows to the neckline.
  8. Watch volume on the third low and on the approach to the neckline.
  9. Wait for a close above the neckline, then check the stop distance and reward-to-risk before acting.

Confirmation

A triple bottom is confirmed by a close above the neckline. Before that, the third low is exactly where many traders try to get in early, and it is also where many apparent triple bottoms turn into a fourth test or a breakdown.

What makes the confirmation more convincing:

  • A decisive close, not a marginal poke a few ticks through the line.
  • Rising participation: the breakout bar trades noticeably more than recent bars, which a relative volume reading makes easy to see.
  • Follow-through: the next bars hold above the neckline instead of slipping back into the range.
  • A held retest: if price returns to the neckline, old resistance acts as support.

Waiting for a retest gives a tighter stop, but strong breakouts often never retest, so you may miss the move. On intraday charts, remember that a bar trading above the neckline can still finish below it.

Invalidation

The bullish case is in trouble when any of these happen:

  • Price closes decisively below the three lows. Support has failed, and the range may now resolve lower.
  • A breakout reverses back below the neckline and keeps falling, a classic false breakout.
  • The lows start stepping lower, so the equal-lows premise no longer holds.
  • A fourth and fifth test arrive, and the structure turns into a sideways range rather than a reversal.

PatternX has no invalidation logic after a signal or trade opens. The pattern's stop level becomes the stop-loss unless your own stop setting is tighter. For a triple bottom, that structural stop sits halfway between the neckline and the average of the lows, so a deep slide back into the pattern ends the trade before the lows are retested.

Volume

In the textbook version, volume tells the story of sellers running out. The first low often comes on heavy volume, sometimes with a capitulation-style flush. The second and third tests usually see less selling, and the rallies off the lows tend to attract more volume than the declines into them. The breakout through the neckline should show a clear expansion. These are tendencies, not requirements; plenty of valid triple bottoms break the script.

PatternX applies no triple-bottom-specific volume rule and does not compare volume across the three lows. The only volume test is the universal one used for every pattern: the breakout bar must trade at least 1.2× its 20-bar average volume. Separately, the size of that volume surge is one of the factors in the PatternX Score.

Common false signals

Most failed triple bottoms trace back to a handful of mistakes:

  • Buying the third low. Anticipating the breakout feels efficient, but many ranges produce another test or a breakdown instead.
  • Reading a range as a reversal. Without a meaningful decline beforehand, three equal lows are simply the floor of a range, which can break either way.
  • Trusting a marginal break. A close barely above the neckline on thin volume often slips back into the range.
  • Redrawing the neckline. Moving the line after the fact makes every breakout look valid.
  • Ignoring the bigger picture. A breakout on the 15-minute chart directly beneath daily resistance has little room to run.

To reduce them, wait for the close, require expanding volume, check the higher timeframe with multi-timeframe analysis, and size positions so that a failed breakout is a planned, limited loss.

Market context

A triple bottom is most meaningful after an extended decline into a level that has acted as support before, especially when the same support is visible on the higher timeframe. It also carries more weight when the broader market is stabilising rather than accelerating lower.

It is less meaningful in a persistent downtrend where every bounce is sold, in choppy markets with no prior trend, and in the hours before a scheduled event that can override any chart. PatternX does not check for a prior downtrend on this pattern; only its rectangle detectors check the prior trend. Its higher-timeframe check reads the next timeframe up and only adjusts the score, never blocking a signal, so judging the backdrop remains your job.

In crypto markets

Crypto trades around the clock, so triple bottoms form without session gaps, but liquidity still thins out in quiet hours and at weekends. Long wicks complicate equal lows: one exchange may print a wick through support that another never shows, so judge the pattern on the venue you actually trade.

Obvious triple lows attract stop runs, and on perpetual futures a cascade of liquidations can push price briefly through support before it recovers. The funding rate adds context: deeply negative funding while the pattern forms means shorts are crowded, which can fuel a squeeze through the neckline. PatternX only signals crypto symbols with at least $3M of 24-hour volume, and funding feeds both the PatternX Score and PatternX AI's sentiment factor.

In stocks, ETFs and FX

In stocks and ETFs, the overnight gap is the main complication. A stock can open above the neckline, so the first regular-session bar is already the breakout, your entry sits well above the line and the stop distance widens. Earnings releases inside the pattern can create a low that reflects one event rather than repeated tests of support, so treat lows formed on news with caution.

In FX, lows often form in the quieter Asian session and get retested later; breakouts during the London and New York overlap usually carry more participation. PatternX scans traditional markets through your own broker connection, and US day traders should know the pattern day trader rule.

Timeframes

Triple bottoms take time: three tests and two rallies. On 1m to 15m charts they form and fail quickly, and random noise can make lows look equal. On 1h to 1d charts they reflect more participants and are generally treated as more meaningful, at the cost of slower formation.

PatternX scans eight timeframes (1m, 3m, 5m, 15m, 30m, 1h, 4h and 1d); new accounts start with 5m, 15m and 1h. Its triple detector reads a fixed 110-bar window, needs at least 70 bars of data, and requires the three lows to span 16 to 90 bars. Larger formations are not seen on that timeframe, and because 1d is the largest timeframe, a triple bottom whose lows span more than 90 daily bars is outside what PatternX scans.

Example: the logic step by step

For example, take a hypothetical stock on the 1-hour chart. All prices are invented to show the mechanics.

StepLevelHow it is derived
Three lows48.20, 48.60, 48.40Average 48.40; each within 0.5% of it
Rally highs50.10 and 50.60Both more than 2% above the lows
Neckline50.10The lower of the two rally highs
Height1.7050.10 − 48.40
Entry50.30First close above the neckline
Stopabout 49.15Halfway level 49.25, less a 0.2% buffer
Target52.00Entry + height

Risk is about 1.15 per share and reward is 1.70, a reward-to-risk of roughly 1.5. With the platform defaults (10% take-profit, 5% stop-loss), the 5% stop at about 47.79 is wider than the pattern stop, so the pattern stop is used; the 10% target at about 55.33 is farther than the measured move, so 52.00 is used.

A trader who drew the neckline through the higher rally (50.60) would wait for a later trigger and get a different entry, which shows how much the neckline choice matters.

How PatternX detects the Triple Bottom

PatternX's triple-bottom detector is deterministic: the same candles always give the same answer. It reads the last 110 bars of the chosen timeframe and needs at least 70. A bar counts as a swing low when its low is the lowest within three bars on either side, so each low is confirmed three bars after it prints.

  • Three consecutive swing lows spanning 16 to 90 bars from first to third.
  • Equal lows: each within 3% of the three lows' mean.
  • Real rallies: both pullbacks between the lows at least 2% deep.
  • Neckline: the shallower pullback, which for a bottom is the lower of the two rally highs.
  • Recency: the third low no more than 30 bars before the latest bar.
  • Breakout: a fresh close above the neckline on the latest bar, meaning the previous close was not already above it. The latest bar may still be forming.
  • Stop and target: stop = neckline − 50% of the height; target = entry + height.

The universal filters then apply: the breakout candle must finish above its open; its volume must be at least 1.2× the 20-bar average; ATR must be at least 0.05% of price; the liquidity score at least 30; the spread at most 0.25%; order-book imbalance against the long no worse than −0.5; and crypto symbols need at least $3M of 24-hour volume, with broker instruments exempt. No prior-downtrend check applies. More in how PatternX detects patterns.

How PatternX Classic evaluates it

In PatternX Classic, a triple bottom that passes the filters is scored with the 13-factor PatternX Score, from 0 to 100. The detector's geometry is one factor; the others cover breakout strength, volume, trend alignment, the higher timeframe, liquidity, spread, order book, volatility, funding, open interest, PatternX's live win rate on that market and a fixed prior for the pattern. Because trend alignment compares EMA20 and EMA50 with the trade, a reversal caught early can score lower there.

The score becomes the signal's confidence, labelled Elite (80+), High (65+), Medium (50+) or Weak (below 50), and you only see signals at or above your minimum confidence (default 65). The stop is the tighter of your stop-loss and the pattern stop, the target the nearer of your take-profit and the measured move, and setups under 1:1 reward-to-risk are dropped. Unapproved signals expire after 15 minutes, and every order passes the risk engine first.

What PatternX AI adds

PatternX AI, on Pro and Elite, never detects patterns. It evaluates triple bottoms that Classic has already detected and accepted, using a fixed, transparent 8-factor formula. For a fresh reversal, market structure is the factor to watch: it checks whether the last three swing highs and lows within 60 candles agree with a long, which a market that has only just turned may not yet show. Momentum reads RSI(14) in the trade's direction, trend strength compares EMA12 with EMA26, and confluence counts how many of trend, structure, volume and momentum agree.

The setup is vetoed if the context score is below 48, or if structure scores below 35 while momentum scores below 40; otherwise its confidence is re-weighted. Stops, targets, sizing and risk checks stay the same. See Classic vs AI.

Frequently asked questions

How is a triple bottom different from a double bottom?

A triple bottom adds a third test of the same support, so it takes longer to form and shows demand defending the level one more time. PatternX detects them separately: a double bottom needs two lows within 2.5% of each other, 8 to 50 bars apart, while a triple bottom needs three lows within 3% of their mean, spanning 16 to 90 bars.

Should I buy at the third low or wait for the neckline breakout?

Buying the third low gives a tighter stop but no confirmation, and many apparent third lows turn into breakdowns or further tests. PatternX only signals on a fresh close above the neckline.

Which rally high should the neckline go through?

There is no single convention: some traders use the higher high, others a sloped line through both. PatternX uses the lower of the two rally highs, which triggers earlier than a line through the higher one.

Does a triple bottom need a downtrend before it?

In classic technical analysis, yes: it is a reversal pattern, so it needs a decline to reverse. PatternX does not check the prior trend for this pattern, so confirm the decline yourself.

Is a triple bottom more reliable than a double bottom?

There is no universal answer; it depends on the market, the timeframe and the context. PatternX does not claim one either: its score includes a fixed prior per pattern, which is not a measured statistic, and its live win rate on that exchange and symbol once there are at least 10 closed trades.
