Right-Angled Broadening (Ascending)
A flat lower line and a rising upper line; breaks either way.
A right-angled broadening formation has one horizontal boundary and one diverging one. In the ascending version the highs keep rising while the lows hold the same level.
Bulkowski finds breakdowns through the flat base more common than breakouts.
How we define it
- Sloping lines: drawn through swing highs or lows with distinct touches (at least 3 candles apart) within about 0.4 ATR; no swing pokes through a line and no close is outside it before the break
- Lower line horizontal, upper line rising; at least 6 touches in total (3 on one line); the range widens by at least 60%
- Minimum length: 2 months on 1D, 3 months on 1W, 10 days on 4H
- 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
