Ascending Triangle
Also called: rising triangle
A bullish continuation pattern where price makes higher lows under a flat horizontal resistance line, coiling toward an upside breakout.
An ascending triangle forms when buyers keep stepping in at higher and higher prices (a rising lower trendline) while sellers defend one fixed level (a flat upper trendline). The narrowing range shows demand absorbing supply at resistance.
Traders watch for a close above the horizontal resistance on expanding volume as the trigger. The measured-move target is often the height of the triangle added to the breakout level. Like all patterns it can fail — a drop back below the rising support invalidates it.

Frequently asked
Is an ascending triangle bullish or bearish?
It's generally bullish — it's a continuation pattern that usually resolves with an upside breakout above the flat resistance line, though no pattern is guaranteed.
How do you trade an ascending triangle?
A common approach is to enter on a confirmed close above the horizontal resistance with rising volume, place a stop below the most recent higher low, and target the triangle's height projected up from the breakout.
