A bullish chart pattern formed by a horizontal resistance line and a rising support line. It indicates increasing buying pressure and typically resolves with an upside breakout. The pattern is confirmed when price breaks above the flat resistance level with above-average volume, and the measured move target equals the height of the triangle added to the breakout point.
Example
“An ascending triangle formed on the 4-hour chart, and the eventual breakout above resistance triggered a 10% rally.”
