Rounded Top
A rounded top is the mirror of the saucer bottom: an uptrend gradually loses momentum, price flattens into a dome, and a downtrend takes over. It reflects a slow handover from buyers to sellers rather than a sharp rejection.

What has to be true for a Rounded Top to trigger
- A prior uptrend losing momentum
- A smooth, curved top without a sharp spike high
- A gradual rollover on the right side of the dome
How PatternGrade grades it
A smoother, more symmetrical dome over a longer formation raises the grade.
Every scanner grades its hits A+, A or B from the pattern's own measurable structure. The grading is deterministic — the same chart always produces the same grade. It describes how closely the chart matches the pattern, not how likely anything is to happen; no hit rate or probability is attached to a grade. The reasoning is set out in the methodology.
What a Rounded Top looks like in practice
A stock advances from $30 to $58 over eight months, but the last stretch slows: weekly gains shrink, the ranges narrow, and price spends six weeks oscillating between $55 and $58 without making meaningful progress. It then begins drifting lower almost imperceptibly, $56, then $54, then $51, with no single sharp reversal session anywhere. Four months later the chart shows a smooth dome and price is at $42.
How a Rounded Top fails
The dome flattens and price resumes higher. What looked like distribution was a long consolidation. Rounded tops share the rounded bottom's weakness in reverse: they are slow, they have no crisp invalidation level, and a forming one is nearly indistinguishable from a failing one for weeks. Volume is the only early tell, and it is a soft one.
What this pattern is telling you
Rounded tops form slowly and lack a crisp trigger, which makes risk harder to define than in a double top with a clear neckline.

How to scan for Rounded Top setups
PatternGrade rescans every liquid US stock (~4,500 names) for this pattern after every close and returns the hits as a graded list, with the pattern drawn on each chart, so you review setups rather than hunt for them.

Rounded Top FAQ
What is a rounding top pattern?
A slow, dome-shaped topping formation marking a gradual shift from uptrend to downtrend, without a sharp spike high.
How long does a rounded top take to form?
Months, commonly three to twelve on daily bars. The pattern describes a gradual transfer of ownership from buyers to sellers, and that is a slow process by nature. A dome that forms in three weeks is not really this pattern.
How do you confirm a rounded top?
By a decisive break below the level where the dome began, the left rim, ideally on expanding volume. Until then the stock is in a slow, quiet drift, and slow quiet drifts resolve in both directions.
Why are rounded tops hard to trade?
Because there is no single level whose loss says the pattern has failed, and no crisp entry. They demand patience and give little feedback along the way, which is the opposite of what most short setups offer.
What volume behaviour supports a rounded top?
Volume declining through the advance into the dome, then expanding as price rolls over and begins the descent. Volume rising on the right side of the dome while price falls is the clearest confirmation the distribution reading is right.
Patterns a Rounded Top is mistaken for
- Double Top
- A double top has two identifiable peaks. A rounded top has none: the high is an area, not a point.
- Head & Shoulders
- Three discrete peaks with the middle highest. A rounded top has no discrete peaks at all.
- Stage 4 Downtrend
- Weinstein's Stage 3 is the rounded topping area and Stage 4 is the decline that follows. A rounded top is roughly the transition; the Stage 4 scan fires later.
- Inverted Cup & Handle
- An inverted cup and handle is a rounded top with an added handle, a modest drift back up before the breakdown. Without the handle, this pattern fits.
