Triangle Patterns: Ascending, Descending, Symmetrical
Triangle patterns are continuation chart formations that show price consolidating before resuming the prior trend.
What Are Triangle Patterns?
Triangle patterns are chart formations that develop when price consolidates in a narrowing range. They typically act as continuation patterns, meaning price usually breaks out in the direction of the prior trend. There are three main types: ascending, descending, and symmetrical triangles.
Types of Triangles
Ascending Triangle (Bullish)
- A flat top (resistance) and a rising bottom (support)
- Buyers push higher lows while sellers defend the same resistance
- Usually resolves with an upside breakout
Descending Triangle (Bearish)
- A flat bottom (support) and a falling top (resistance)
- Sellers push lower highs while buyers defend the same support
- Usually resolves with a downside breakdown
Symmetrical Triangle (Neutral)
- A falling top and a rising bottom
- Both buyers and sellers converge toward a point
- Breakout direction depends on the prior trend
What They Signal
Triangles signal that price is consolidating before the next directional move. The narrowing range shows buyers and sellers reaching equilibrium, but the eventual breakout reveals who ultimately wins.
| Triangle Type | Prior Trend | Expected Breakout |
|---|---|---|
| Ascending | Bullish | Up |
| Descending | Bearish | Down |
| Symmetrical | Either | In trend direction |
How to Trade Them
- Identify the trend leading into the triangle.
- Draw the trendlines connecting the highs and lows.
- Wait for the breakout. Enter when price closes outside the triangle with strong volume.
- Place your stop-loss just inside the opposite side of the triangle.
- Measure the target. Project the height of the triangle's widest point from the breakout.
Trading Example
A stock in an uptrend rises from $40 to $55, then forms an ascending triangle with resistance at $55 and rising support from $50 to $53. When price breaks above $55 on strong volume, traders enter long with a stop near $53. The target is $55 - $50 = $5, projected up from $55 to give a target of $60.
Common Mistakes
- Entering before the breakout confirms
- Ignoring volume — breakouts on low volume are more likely to fail
- Forgetting that triangles usually continue the prior trend, not reverse it
When to Be Cautious
Triangles can break out in either direction, especially symmetrical triangles. Always wait for confirmation and never assume the breakout direction before it happens.
Triangle patterns are popular among swing traders because they offer clear breakout levels, defined risk, and measurable targets based on the pattern's geometry.
