Descending Channel

Two parallel, falling trendlines containing price; breaks either way.

A falling channel is an orderly downtrend; a close above the upper line ends it.

Breakouts from falling channels are often retested.

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
At least 3 distinct touches on each line; parallel (height ratio 0.8-1.25) and clearly falling
Both lines tested in the last third; closes reach the top and bottom fifth at least twice each
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
