Rounding Top
Moderate ConsensusThe mirror image of the rounding bottom: a gradual, dome-shaped bearish reversal in which an advance slowly loses momentum, flattens into a broad top, and then slowly curves downward before breaking below the level where the advance began.
Candlestick chart showing a slow advance that gradually flattens into a broad, rounded dome over an extended period, then gradually curves downward and breaks below the support level where the original advance began.

Identification Criteria
- Forms over a comparatively long period — weeks to months — rather than a sharp, spike-like top.
- The advance into the pattern loses upward momentum gradually rather than reversing sharply.
- The top is broad and rounded, often with multiple minor lower highs rather than one sharp peak.
- Volume classically fades as the dome forms and price stalls near the highs, then expands again as price curves down and breaks the base.
Formation Logic
The rounding shape reflects a slow shift in sentiment rather than a single decisive event — buyers gradually run out of demand while sellers gradually gain the upper hand, without a sharp catalyst. This is common at the end of long, grinding advances rather than sharp blow-off tops.
Breakout / Confirmation Rule
Confirmation comes from a decisive close below the support level marked by the price at which the original advance began (the "base" beneath the dome). Because the pattern forms slowly, calling the breakdown before price actually approaches and breaks this base is a common error.
Measured-Move Price Target
A commonly used, purely illustrative technique: measure the height of the dome from its base to its highest point, then project that same distance below the breakdown point. Given the pattern's long formation time, treat this 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 bull-market pause for the early curve of a rounding top.
- The lack of a sharp, obvious trigger point makes premature entries common.
- A rounding top that fails to show declining volume on the way down carries a higher risk of stalling just above support rather than breaking it.
