Descending Triangle
A descending triangle forms when price repeatedly holds the same horizontal support while the highs step steadily lower. Sellers accept lower prices on each rally while a fixed block of demand sits at the floor. That compression conventionally resolves downward.

What has to be true for a Descending Triangle to trigger
- A horizontal support level touched more than once
- A falling sequence of highs above it
- Highs tracking the descending line tightly
- Range narrowing as the lines converge
How PatternGrade grades it
A flatter floor, more clearly falling highs and a longer formation raise the grade.
Every scanner grades its hits A+, A or B from the pattern's own measurable structure. The grading is deterministic — the same chart always produces the same grade. It describes how closely the chart matches the pattern, not how likely anything is to happen; no hit rate or probability is attached to a grade. The reasoning is set out in the methodology.
What a Descending Triangle looks like in practice
A stock holds $48 four times over ten weeks while its highs step down from $56 to $53 to $51 to $49.20. Drawing a line across the highs gives a clear falling ceiling against the flat $48 floor. Volume contracts as the apex approaches, then expands sharply on the session that closes at $46.40, below the support that had held four times.
How a Descending Triangle fails
Price breaks upward through the falling trendline instead. That is a genuine reversal of the pattern's premise. Sellers were supposed to be getting more aggressive while buyers held a fixed line, and an upside break says the opposite. Descending triangles in strong markets break upward often enough that treating the downside as a foregone conclusion is a mistake.
What this pattern is telling you
Descending triangles are conventionally bearish but break upward often enough that direction should not be assumed in advance.

How to scan for Descending Triangle setups
PatternGrade rescans every liquid US stock (~4,500 names) for this pattern after every close and returns the hits as a graded list, with the pattern drawn on each chart, so you review setups rather than hunt for them.

Descending Triangle FAQ
Is a descending triangle always bearish?
No. It is conventionally read as bearish because of the falling highs, but the pattern breaks upward a meaningful share of the time.
Is a descending triangle always bearish?
It leans bearish because the falling highs suggest sellers accepting progressively lower prices while buyers defend a fixed level. But it resolves upward regularly, particularly in strong markets, and the falling trendline is the level that says so. PatternGrade reports the structure and the levels that define it, and does not assert which way it will resolve.
How many touches are needed?
At least two on the horizontal support and two along the falling highs, with three at each being stronger. Fewer than that and the lines are being drawn through noise, which is the most common way this pattern is mis-identified.
Where does a descending triangle break down?
On a close below the horizontal support, ideally on expanded volume. PatternGrade draws that level from the pattern's own geometry. A break on light volume is the classic false move and is frequently reclaimed.
What is the target on a descending triangle?
The conventional measured move is the height of the triangle at its widest, projected down from the breakdown. It is a geometric projection rather than a prediction, and PatternGrade presents it alongside the structural invalidation level.
Patterns a Descending Triangle is mistaken for
- Ascending Triangle
- The bullish mirror: flat ceiling, rising floor. Which boundary is horizontal determines the pattern.
- Symmetric Triangle
- Both boundaries converge with neither horizontal, and no directional lean.
- Triple Top
- A triple top has flat highs. A descending triangle has a flat floor and falling highs. The horizontal line is on the opposite side.
- Falling Wedge
- A falling wedge has both boundaries falling and converging, and is read bullishly. A descending triangle's floor is horizontal.
