Double Bottom

Two troughs at the same price after a decline, separated by a clear peak; completes on a close above the peak.

The double bottom ("W") is the mirror image of the double top: two tests of the same low, confirmed by a close above the high between them.

Rectangles with two lows are listed as rectangle bottoms instead.

How we define it

Two zigzag troughs within about 0.4 ATR of each other, nothing below them in the pattern
Middle peak at least 4 ATR and 5% (4H) / 8% (1D, 1W) above the troughs
Price fell into the first trough (prior trend down)
No close below the troughs or above the neckline before the breakout
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
