Triple Bottom
The Triple Bottom is a bullish reversal pattern — the mirror image of the Triple Top. It forms after a sustained downtrend and consists of three troughs at approximately the same price level, separated by two interim rally peaks. The line connecting those peaks forms the "neckline." Each time price bounces off the support zone, it demonstrates strong buying interest at that level. The pattern is confirmed when price breaks above the neckline after the third bounce, signaling that sellers have exhausted themselves and buyers are taking control.

Pattern Anatomy
The Triple Bottom has four key structural elements that must be present for a valid formation:
- Three troughs at approximately the same level — The troughs do not need to be identical to the penny, but they should be close enough that a clear horizontal support zone is visible. Minor variations (within 1-3% of each other) are normal. The key idea is that the same price floor is being tested repeatedly.
- Two peaks between the troughs (neckline) — After each trough, price rallies to an interim high before falling back. The line connecting these two peaks forms the neckline — the resistance level that must break for the pattern to confirm. The neckline can be horizontal or slightly sloped.
- Increasing volume on each test of support is ideal — While not strictly required, classic technical analysis suggests that volume should ideally increase (or at least hold steady) on the second and third bounces off support. This indicates growing buying conviction at the support level. Volume should also spike on the neckline breakout.
- Breakout above the neckline confirms the pattern — The Triple Bottom is not complete until price closes above the neckline. Until that happens, the three troughs could simply be part of a sideways trading range that eventually breaks down. Some traders wait for a pullback to retest the neckline (now support) before entering.
How to Trade the Triple Bottom
The standard trading approach involves three elements: entry, target, and stop loss.
- Entry — Enter a long position when price breaks above the neckline on a closing basis. More conservative traders wait for the price to pull back and retest the neckline from above (the old resistance becomes new support) before entering.
- Measured move (price target) — Measure the vertical distance from the trough level to the neckline. Project that same distance upward from the neckline breakout point. For example, if the troughs are at $30 and the neckline is at $35, the measured move target is $40 (i.e., $35 plus $5).
- Stop loss — Place the stop below the trough level. If price falls back below the support zone that held three times, the pattern has failed and you want to exit. A common placement is slightly below the lowest of the three troughs to allow for minor wick variations.
Triple Bottom vs. Inverse Head & Shoulders
The Triple Bottom and Inverse Head and Shoulders are both bullish reversal patterns with three troughs, but they differ in one critical way:
- Inverse Head and Shoulders: the middle trough is deepest — In this pattern, the center trough (the "head") dips lower than the two outer troughs (the "shoulders"). The asymmetry of the middle low being deeper is what defines the pattern.
- Triple Bottom: all three troughs are roughly equal — In a Triple Bottom, all three troughs form at approximately the same horizontal support level. There is no distinctly deeper middle trough. This uniformity is the defining characteristic.
- Triple Bottom demonstrates very strong support — The fact that price bounces off the exact same level three times (rather than making a lower low in the middle) suggests that the support zone is exceptionally strong. Buyers are consistently stepping in at the same price, absorbing all selling pressure. This can make the eventual breakout particularly powerful.
Expert References
- Edwards & Magee, Technical Analysis of Stock Trends (1948, multiple editions) — Describe the Triple Bottom as a variant of the rectangle bottom, emphasizing that the three tests of support without a breakdown create a strong base. They consider it a reliable reversal formation, particularly when accompanied by volume confirmation on the breakout.
- Thomas Bulkowski, Encyclopedia of Chart Patterns (2005) — Provides statistical analysis of Triple Bottom patterns. Bulkowski notes that the pattern has a solid success rate as a bullish reversal, though he cautions that "triple" patterns in general are rarer than doubles, making the sample size smaller. He also emphasizes that a confirmed breakout above the neckline is essential — patterns that don't break out often continue sideways or break down.
- John Murphy, Technical Analysis of the Financial Markets (1999) — Covers the Triple Bottom as one of the major reversal patterns, noting that the longer the pattern takes to form and the wider the price swings between troughs and peaks, the more significant the eventual breakout tends to be.
Controversy & Limitations
- Subjectivity in identification: How close do the three troughs need to be for the pattern to qualify? There is no universally agreed-upon tolerance. One analyst might accept troughs within 3% of each other, while another insists on 1%. This subjectivity means the same chart can be read differently by different traders.
- Confusion with a trading range: Three bounces off support could simply be the lower boundary of a horizontal trading range (rectangle). The difference is that a Triple Bottom implies a reversal after a prior downtrend, while a rectangle is a continuation pattern. If there's no clear prior downtrend, the formation is more likely a rectangle than a Triple Bottom.
- Long formation time: Triple Bottoms can take weeks or months to develop because the market needs to test support three times with meaningful rallies in between. This patience requirement is a practical limitation — traders may tie up capital waiting for a breakout that may never come, or the pattern may resolve into a breakdown instead.
