Rounding Bottom
Moderate ConsensusA gradual, saucer-shaped bullish reversal pattern in which a decline slowly loses momentum, flattens into a broad bottom, and then slowly curves back upward before breaking above the level where the decline began.
Candlestick chart showing a slow decline that gradually flattens into a broad, rounded base over an extended period, then gradually curves upward and breaks above the resistance level where the original decline began.

Identification Criteria
- Forms over a comparatively long period — weeks to months — rather than the sharp V-shapes seen in panic reversals.
- The decline into the pattern loses downward momentum gradually rather than reversing sharply.
- The bottom is broad and rounded, often with multiple minor higher lows rather than one sharp trough.
- Volume classically traces a matching "U" or saucer shape: high on the way down, lowest near the middle of the base, and expanding again as price curves up and approaches the old high.
Formation Logic
The rounding shape reflects a slow shift in sentiment rather than a single decisive event — sellers gradually run out of supply while buyers gradually accumulate, without a sharp catalyst. This is common at the end of long, grinding declines rather than sharp panics.
Breakout / Confirmation Rule
Confirmation comes from a decisive close above the resistance level marked by the price at which the original decline began (the "rim" of the saucer). Because the pattern forms slowly, a premature breakout call before price approaches this rim is a common error.
Measured-Move Price Target
A commonly used, purely illustrative technique: measure the depth of the saucer from the rim to the lowest point of the base, then project that same distance above the breakout point. Given the pattern's long formation time, this projection should be treated as a rough, long-horizon reference rather than a precise level.
Common Pitfalls
- Because the pattern forms slowly, it is easy to mistake an ordinary consolidation or a bear-market rally for the early curve of a rounding bottom.
- The lack of a sharp, obvious trigger point makes premature entries common.
- A rounding bottom that fails to expand volume on the approach to the rim carries a higher risk of stalling just below resistance.
