Rounding Top

A Rounding Top is a bearish reversal pattern that develops slowly after a prolonged uptrend. It is recognized by:

• A gradual flattening of the uptrend into a sideways curve.
• Price making marginally higher highs that eventually turn into marginally lower highs, forming a dome shape.
• Volume that peaks early in the curve, then declines steadily as the top matures.
• Final confirmation when price breaks below the support level (the base of the curve).

Unlike sharp reversal patterns (double tops, head & shoulders), the rounding top unfolds over weeks or months, giving it the appearance of a smooth “arch.”

The rounding top represents gradual distribution and erosion of bullish enthusiasm:

• Early curve: Bulls remain confident, but volume begins to taper. Gains are slower, and sellers start quietly unloading into strength.
• Mid-curve: Buyers continue to step in but are less aggressive. Each rally is weaker, and new highs come on lower volume. Market participants begin to doubt sustainability.
• Late curve: Sellers dominate. Bulls are still present but increasingly trapped as price slips below prior lows.
• Breakdown: Once the base of the curve fails, stop-losses trigger, bulls capitulate, and bears seize control.

This psychology is less dramatic than a blow-off top but no less damaging: it reflects exhaustion, not panic.

Bulkowski’s studies show rounding tops are solid bearish signals:

• Downward breakout frequency: ~64%.
• Failure rate: ~15%.
• Average decline after breakdown: ~20%.
• Pullback frequency: ~55%.
• Target met rate: ~63%.

Though reliable, rounding tops can be frustrating because they develop slowly and offer little immediate excitement.

Entry:

• Conservative: Short on confirmed breakdown below support.
• Aggressive: Enter short as the dome forms, once lower highs are evident.

Stop loss: Above the last swing high inside the top or above the “shoulder” of the curve.

Targets: Minimum = depth of the pattern projected downward. Secondary = prior support zones.

Invalidation: Sustained rally back above the dome cancels the setup.

• False sense of security: Traders underestimate the slow deterioration and overstay bullish positions.
• Early shorts: Entering too soon (before curve matures) risks chop.
• Flat bases: If support is weak, breakdown may lack momentum.
• Time element: The longer the top takes to form, the stronger the eventual move.
• Volume tells: Declining volume across the curve strengthens the bearish case.

• If volume remains strong during the supposed “curve” — bulls may still be in control.
• If the pattern forms in very short timeframes (minutes/hours) — these are often noise.
• If broader market context is strongly bullish, which can override local tops.
