Key Takeaways
- An ascending triangle combines one flat horizontal resistance level with a rising line drawn under a series of higher lows.
- Mark the repeated highs near resistance and the higher swing lows that define the rising boundary.
- Choose the activation event. This example uses a close above the $100 resistance level.
- The upside objective adds the $9.90 base height to $100 resistance, giving $109.90.
- Use an explicit entry and stop reference to calculate trade distance and size.
What is an ascending triangle?
An ascending triangle is a chart pattern with repeated highs near one horizontal resistance level and a rising support line beneath its pullbacks. Each low sits higher than the last as price presses into the same ceiling. A break above resistance activates the upside setup, a break below the rising line activates the downside setup, and the pattern’s height sets a measured price objective.
How to identify an ascending triangle
Each boundary needs at least two swing points: two highs near the ceiling and two rising lows under it. Set the breakout rule, such as a close above resistance, before price gets there.
The example advances from $84, then makes four highs near $100. Its first three main lows are $90.10, $93.60 and $96.30. The support line passes through the first and third of those lows; the middle low is above it.
Formula
Pattern height = horizontal resistance level − lowest swing low inside the triangle; Measured target = breakout level + pattern height- The base height is $100 resistance minus the first $90.10 swing low.
- The target projects from the $100 resistance, while the trade enters at the $101.60 breakout close, so the reward runs from $101.60.
- Compare the entry-to-target distance with the entry-to-stop distance.
Worked Example
A stock advances from $84 and makes four local highs near $100. Its first three main pullbacks bottom at $90.10, $93.60 and $96.30. Draw rising support through the $90.10 and $96.30 lows and horizontal resistance at $100.
- Pattern height: 100.00 − 90.10 = 9.90 points
- Measured target: 100.00 + 9.90 = 109.90
- Assumed $101.60 breakout entry − $97.90 stop reference below the rising line = $3.70 per share
- Reward to risk against the measured target: (109.90 − 101.60) / 3.70 = 2.24 to 1
The example closes at $101.60 with volume twice the preceding 20-session average, returns to $100.40, then advances to $109.20. That is $0.70 below the $109.90 boundary-anchored objective. Track the $97.90 stop reference separately from the $100 retest level.
Ascending triangle breakout and price target
The rule requires a close above $100. Price closes at $101.60, activating the upside setup.
The base height is $100 − $90.10 = $9.90. Projecting from resistance gives $100 + $9.90 = $109.90.
Assume entry at $101.60 and a stop reference of $97.90. At the breakout bar, rising support sits at $98.88, placing the stop reference below it. Entry-to-stop distance is $3.70 and entry-to-target distance is $8.30, a 2.24 ratio.
Ascending triangle retest and entry choices
The example returns to $100.40 after the breakout and then reaches $109.20, finishing $0.70 below the objective. The $100.40 retest holds above the old $100 ceiling. The $97.90 stop sits below rising support, so it triggers only if the breakout fails back through the pattern.
Each entry sizes differently. A buy near rising support, the $101.60 breakout close and the $100.40 retest each sit a different distance from the $97.90 stop, so recompute the size for the entry you take.
Ascending vs descending and symmetrical triangles
A Descending Triangle reverses the geometry with flat support and falling highs. A Symmetrical Triangle has both falling highs and rising lows.
Use the actual breakout direction and preceding trend to classify continuation or reversal. The line intersection identifies the geometric apex.
How traders use an ascending triangle
Breakout volume in this example is twice the preceding 20-session average. Relative Volume gives the corresponding participation comparison.
Gamma Exposure shows whether a call wall stands between the $100 breakout and the $109.90 objective, and the Options Profit Calculator prices each structure at that objective from the actual chain.
Limitations of the ascending triangle
- Trade the break that occurs. A close above $100 activates the upside setup, and a break below rising support activates the downside setup.
- Fix the boundary rule before the break. Which highs count as near resistance and which lows anchor the rising line change the height, the target and the stop.
- The measured move sets the target. In the example, price tops out at $109.20, $0.70 short of $109.90, so a sell limit at the target never fills; trail a stop as price nears it to keep the gain.
- Set the stop below the rising line before entry. If a breakout fails and returns inside the triangle, that stop reference defines the planned loss.
- Write the chart interval and the activation rule into the plan. A close above resistance and an intrabar trade above it trigger at different times.
Bottom line
An ascending triangle shows price pressing into flat resistance while the lows rise beneath it, which gives a clear breakout level, a stop below rising support and a measured objective. Define the activation rule and the boundaries before the break, size from the entry-to-stop distance, and manage the exit as price approaches the target.
