A descending triangle pairs a horizontal support line with a falling line across the highs. Price keeps bouncing off the same floor, but each bounce tops out lower than the last — sellers are getting more aggressive while one bid level absorbs the pressure. The pattern conventionally resolves with a breakdown through the flat floor.
Every test of a support level consumes some of the demand resting there. Lower highs show that sellers need less and less of a rally to find willing exits, and when the floor's bids are finally exhausted, the breakdown can be abrupt — every earlier bounce buyer is stopped out at once.
Descending triangles inside downtrends are the textbook bearish continuation; the same shape after a long base occasionally breaks upward, which is why confirmation matters more than the shape alone.
How it forms, phase by phase
1
The floor
Price bounces from the same horizontal level at least twice — identifiable demand.
2
Lower highs
Each bounce is weaker, topping below the previous high. The falling trendline forms as sellers press earlier each time.
3
Compression
The triangle narrows and volume contracts; price spends more time pinned against the floor.
4
Breakdown
The floor gives way on a closing basis, typically with a volume spike as resting stop-losses trigger.
How traders trade it
1The trigger is a close below the flat support, not the third or fourth touch of it — floors that have held repeatedly do sometimes keep holding.
2Watch the bounces: progressively weaker, lower-volume rallies off the floor are the internal confirmation that demand is being ground down.
3Project the triangle's base height below the breakdown for a target; the broken floor then acts as resistance on any retest.
4Stops go above the most recent lower high; a reclaim of the floor plus a higher high cancels the pattern.
The target calculation
Target = breakdown level − height of the triangle's base (the distance between the flat floor and the pattern's first high).
Worked example
1.A coin bounces repeatedly off $0.50 while rally highs fall from $0.62.
2.Base height: $0.62 − $0.50 = $0.12.
3.On a close below $0.50, the measured target is $0.50 − $0.12 = $0.38.
4.Stop above the last lower high at $0.55 risks $0.05 to make $0.12 — a 1 : 2.4 risk-reward.
Descending Triangle: key facts
Lower highs into flat support is distribution in its clearest visual form.
The more times a floor is tested in quick succession, the fewer resting bids remain — frequent tests weaken support rather than proving it.
Breakdowns often gap or accelerate because clustered stop-losses sit just under an obvious, widely-watched level.
A failed descending triangle — breaking up through the falling trendline instead — traps shorts and can rally hard; confirmation cuts both ways.
The pattern is the bearish mirror of the ascending triangle.
What it doesn't tell you
Obvious floors attract both stop-loss clusters and bargain hunters, so descending triangles produce more fake breakdowns than the textbook admits — especially in choppy, low-volume conditions. The shape alone is not a short thesis: demand the closing break, and remember the measured move is an estimate, not an entitlement.
Descending Triangle FAQ
Is a descending triangle always bearish?
No — it leans bearish, particularly inside a downtrend, but a meaningful minority break upward, especially when the pattern forms after a long decline as part of a base. That is why traders treat the closing break of the floor (or of the falling trendline) as the signal, not the shape itself.
How is a descending triangle different from a falling wedge?
A descending triangle has a flat, horizontal floor with falling highs and leans bearish. A falling wedge has both boundaries sloping down and converging, and leans bullish. The flat floor is the distinguishing feature — and the direction of the expected break is opposite.
Where do you put a stop-loss when shorting a descending triangle?
Above the most recent lower high inside the triangle, or more conservatively above the falling trendline. If price reclaims the broken floor and starts printing higher highs, the breakdown has failed and the trapped-shorts rally risk takes over.

1. Why do repeated tests of the flat floor weaken it rather than prove it?
2. Flat floor $0.50, first high of the pattern $0.62. Breakdown target?
3. Price breaks UP through the falling trendline instead of down. What now?
