Rounding Top
A long, dome-shaped rise and fall back down to the starting level; completes on a close below the lip.
The mirror image of the rounding bottom: a slow arc over the top and a breakdown through the starting level.
Rare.
How we define it
- Lip: a swing low that no close goes below before the breakdown
- At least 1.5 times the normal minimum length; at least 5 ATR and 10% tall; the high in the middle 30-70%; closes fit a dome-shaped curve (R² ≥ 0.75)
- Breakout (up) / breakdown (down): the first candle close beyond the boundary by at least 3% on 1D and 1W (1.5% on 4H)
- Failed breaks: a breakout or breakdown that closes back inside the boundary within 6 candles on 4H, 5 on 1D or 3 on 1W is removed from the list
- Trend filter: breakouts only above the 200-period EMA (40-week EMA on 1W), breakdowns only below it
- Watchlist: the pattern is complete but unbroken and price is within 3% (or 1 ATR, at most 6%) of the boundary
