Ascending Triangle: definition and measured success rate
Data as of 31.07.2026 · back-test since 07/2019
An ascending triangle is a bullish continuation pattern with a flat resistance line on top and a series of rising lows below. Buyers accept ever-higher prices while sellers defend one fixed level — pressure builds until the level breaks. In chartval's back-test, it worked in 52 of 100 comparable cases (7,098 occurrences).
How does a ascending triangle form?
Each pullback ends higher than the last, showing buyers stepping in earlier every time, while the same ceiling caps each advance. The narrowing gap compresses the market like a spring. The pattern completes when price closes above the flat resistance line.
How reliable is the ascending triangle?
In chartval's historical back-test across 274 stocks, ETFs and cryptocurrencies, the ascending triangle reached a 5 percent move in the signal direction before a 5 percent counter-move in 52 of 100 cases (7,098 occurrences evaluated since 07/2019; data as of 31.07.2026). Past statistics are not a reliable indicator of future results.
Measurement: a case counts as a hit when price moved 5 percent in the signal direction before moving 5 percent against it, based on closing prices, within a maximum of 120 candles after the trigger.
