The ascending triangle is a bullish chart pattern that signals buyers are gaining control. Characterized by a flat resistance level and rising support, this pattern shows that buyers are willing to pay higher and higher prices while sellers defend a specific level. When that resistance finally breaks, the result is often an explosive move higher.
What is an Ascending Triangle?
An ascending triangle forms when price consolidates between a horizontal resistance line and an upward-sloping support line. Each time price pulls back, buyers step in at higher levels. Meanwhile, sellers defend the same resistance level. This creates a coiling effect that typically resolves with an upward breakout.
Pattern Characteristics
- Flat Resistance: Multiple touches of the same horizontal level, typically 2-4 times.
- Rising Support: Higher lows forming an ascending trendline.
- Converging Lines: The pattern narrows as price approaches the apex.
- Decreasing Volume: Volume typically contracts as the pattern develops.
- Breakout Direction: Statistically breaks upward about 70% of the time.
Why It Works: The ascending triangle shows that buyers are aggressively accumulating shares at higher prices, while sellers are concentrated at one level. When that selling pressure is absorbed, the breakout is powerful.
Identifying the Pattern
A valid ascending triangle requires specific criteria to be met.
Validation Requirements
- At Least Two Highs: Price must test the resistance level at least twice.
- At Least Two Higher Lows: The support line needs at least two touches at successively higher levels.
- Duration: Pattern typically forms over 3 weeks to 3 months on daily charts.
- Volume Profile: Volume should generally decrease as the pattern develops.
Ascending Triangle Example
AMD stock finds resistance at $120 three times over six weeks. Each pullback finds support at higher levels: $105, $110, $113. Volume contracts during the pattern. Then AMD breaks above $120 on twice-average volume, confirming the ascending triangle breakout.
Trading the Ascending Triangle
This pattern offers clear entry points, stops, and targets.
Entry Strategies
- Breakout Entry: Buy when price closes above the resistance line with strong volume. The most common approach.
- Anticipation Entry: Buy near the rising support line, anticipating the breakout. Better risk-reward but higher failure rate.
- Pullback Entry: Wait for the breakout, then buy if price pulls back to test the former resistance as support.
Volume Confirmation
Volume is critical for confirming ascending triangle breakouts.
- During Pattern: Volume should decrease, showing consolidation.
- On Breakout: Volume should spike significantly, at least 50% above average.
- After Breakout: Sustained volume confirms the move is real.
Warning: Breakouts on low volume often fail. Wait for confirmation or use smaller position sizes.
Price Target Calculation
The measured move target is based on the height of the triangle at its widest point.
Target Calculation
- Resistance level: $120
- First support low: $105
- Pattern height: $120 - $105 = $15
- Price target: $120 + $15 = $135
Stop Loss Placement
- Below the Pattern: Place stop below the most recent higher low. Conservative approach.
- Below the Breakout Point: Tighter stop just below resistance after breakout.
- Below the Support Line: A break of the rising support invalidates the pattern.
Pattern Context Matters
The ascending triangle can appear in different market contexts with varying implications.
In an Uptrend (Continuation)
When an ascending triangle forms during an established uptrend, it typically acts as a continuation pattern. The breakout resumes the prior trend direction. These tend to be the most reliable setups.
At Market Bottoms (Reversal)
Ascending triangles can also form at the end of downtrends, signaling a potential reversal. While less common, these patterns can mark significant turning points.
Failed Breakouts
About 30% of ascending triangles break down instead of up. If price breaks below the rising support line, it can lead to sharp declines as trapped buyers exit.
Common Mistakes
Avoid these errors when trading ascending triangles.
- Forcing the Pattern: Not every consolidation is an ascending triangle. The support line must clearly slope upward.
- Ignoring Volume: Low-volume breakouts frequently fail. Be patient for proper confirmation.
- Trading Near the Apex: Breakouts near the apex point are less reliable. The best breakouts occur in the second half of the pattern but before reaching the apex.
- Ignoring Market Conditions: Ascending triangles work best in bull markets. Be cautious in bear markets.
- Missing False Breakouts: Quick breaks above resistance that immediately reverse are warning signs.
Timeframe Considerations
Ascending triangles can form on various timeframes.
- Weekly Charts: Most significant, patterns can take months to form. Large price targets.
- Daily Charts: The sweet spot for swing traders. Clear patterns, reasonable holding periods.
- Hourly Charts: Good for day traders, but more noise and false signals.
- Lower Timeframes: Very short patterns are less reliable. Use with other confirmation.
Multiple Triangle Tests
Sometimes price tests resistance many times before breaking out.
What Multiple Tests Mean
- 3+ Tests: Shows strong resistance, but also shows persistent buying interest.
- Building Pressure: Each test absorbs more selling. Eventually, sellers are exhausted.
- Stronger Breakouts: Patterns with more tests often have more powerful breakouts when they finally occur.
Combining with Indicators
Increase your edge by using additional technical tools.
Useful Confirmations
- RSI: RSI above 50 and rising supports the bullish breakout thesis.
- Moving Averages: Price above the 50-day and 200-day moving averages confirms the bullish trend.
- MACD: A bullish MACD crossover during the pattern adds confidence.
- On-Balance Volume: Rising OBV during the pattern shows accumulation.

Summary
The ascending triangle is a reliable bullish pattern characterized by flat resistance and rising support. Look for patterns with clear structure, decreasing volume during formation, and explosive volume on breakout. Calculate targets using the pattern height and place stops below the recent higher low. Remember that about 70% break upward, but always be prepared for the 30% that fail. With proper identification and risk management, ascending triangles can be highly profitable trading setups.
