Descending Triangle

In simple terms

A descending triangle is a chart pattern that looks like a triangle tipped on its side, where the bottom stays flat but the top keeps getting lower. It usually signals that the price is about to drop, like water finding its way down a slanted surface.

Definition

Bearish continuation pattern with a flat bottom and falling highs.

In depth

A descending triangle forms when price action creates a series of lower highs while maintaining support at a relatively flat bottom level, typically over multiple candlesticks or trading periods. This pattern reflects increasing selling pressure at successively lower price levels combined with consistent buying interest at the support floor, creating an asymmetric squeeze. As the triangle compresses and price approaches the support level, a breakout below the base usually occurs with volume confirmation, triggering a bearish continuation move. Traders use the height of the triangle measured from the initial highs to the base to project the downside target distance after the breakdown occurs.

How does Descending Triangle work?

Price keeps finding buyers at roughly the same floor while each rally peaks lower than the one before. A horizontal line under the lows and a downward-sloping line across the highs converge, squeezing the range. Volume usually contracts as the triangle narrows. The pattern resolves when price closes clearly outside one boundary; a break below the flat support is the more commonly cited outcome, because sellers are stepping in earlier on each attempt. The triangle's widest height, projected from the break, serves as a rough reference. Upward resolutions through the falling highs also happen regularly.

An example

Illustratively, an asset holds $50 on three separate dips while its rallies top out at $62, $58, and $54. The widest height is $12, from $62 down to $50. A close below $50 gives a rough $38 reference; a close above the falling upper line would negate the pattern instead. These are invented numbers, and the level can hold or fail without warning.

Figures are illustrative only.

What beginners get wrong

• Treating the flat support as certain to break ignores that a substantial minority of descending triangles resolve upward instead.
• A level tested five or six times is not stronger for it, and repeated tests frequently precede a failure rather than a hold.
• Reading a descending triangle on a five-minute chart and giving it daily-chart weight confuses short-term noise with market structure.
• Nothing in the geometry caps how far price can fall, so losses beyond the measured height are entirely possible.
