Ascending Triangle

The Ascending Triangle is typically a bullish continuation pattern. It features a flat horizontal resistance line at the top and a rising support trendline at the bottom. Each successive low is higher than the last, showing that buyers are increasingly aggressive, while sellers continue to defend the same price level. The pattern usually resolves with an upside breakout once buying pressure finally overwhelms the resistance.

Pattern Anatomy

• Flat Resistance: A horizontal line at the top where price repeatedly stalls — requires at least 2 touches to be valid
• Rising Support: An ascending trendline connecting at least 2 higher lows, showing buyers stepping in at progressively higher prices
• The two lines converge to form a triangle shape as the price range compresses
• Volume typically decreases as the pattern develops, then expands on the breakout
• The breakout typically occurs about 2/3 to 3/4 of the way through the pattern, before price reaches the apex

How to Trade

• Entry: Enter on a breakout above the flat resistance line, ideally confirmed by a volume surge
• Price Target: The measured move equals the height of the triangle at its widest point, projected upward from the breakout level
• Stop Loss: Place a stop below the last higher low or just below the rising support trendline
• False Breakouts: Be cautious of intraday pierces above resistance — wait for a candle to close above the level before committing, not just an intraday wick
• Volume confirmation is critical — a breakout on low volume is more likely to fail

Why It's Bullish

The ascending triangle is considered bullish because the higher lows tell a story: buyers are willing to step in earlier and at higher prices each time, while sellers are only defending a fixed level. This means demand is increasing while supply remains constant. Eventually, the growing buying pressure overwhelms the resistance and price breaks out to the upside.

Expert References

• Edwards & Magee, Technical Analysis of Stock Trends — one of the earliest and most authoritative descriptions of the ascending triangle as a continuation pattern in an uptrend
• Thomas Bulkowski, Encyclopedia of Chart Patterns — found that ascending triangles break upward approximately 64% of the time, making it a statistically significant but not guaranteed bullish pattern
• John Murphy, Technical Analysis of the Financial Markets — classifies the ascending triangle as inherently bullish regardless of the prior trend, noting the pattern of higher lows as evidence of accumulation

Controversy & Limitations

• Not always bullish — according to Bulkowski's research, ascending triangles break downward about 36% of the time, so the pattern is far from a guaranteed upside move
• There is ongoing debate about whether this is truly a "continuation" pattern or simply a common formation that can appear in any trend context
• Some traders argue that ascending triangles forming after an extended uptrend may actually signal distribution rather than continuation
