Chart Patterns: Triangles
Triangles are continuation patterns that show consolidation before the next move. Understanding the three types helps you anticipate breakout direction and magnitude.
[DEFINITION] Triangle Pattern: A consolidation pattern formed by converging trendlines as price makes lower highs and/or higher lows, eventually breaking out in one direction.
### Types of Triangles
**Ascending Triangle (Bullish)**
- Flat upper resistance line
- Rising lower support line
- Buyers getting more aggressive; sellers holding firm
- Usually breaks upward
**Descending Triangle (Bearish)**
- Declining upper resistance line
- Flat lower support line
- Sellers getting more aggressive; buyers holding firm
- Usually breaks downward
**Symmetrical Triangle (Neutral)**
- Declining upper line AND rising lower line
- Price compresses into the apex
- Can break either direction; trade the breakout
[TIP] Ascending and descending triangles have a directional bias, but no pattern is guaranteed. Always wait for the actual breakout.
### Trading Triangles
**Entry:** On breakout from the triangle with volume
**Stop-loss:** Inside the triangle (below support for longs, above resistance for shorts)
**Target:** Height of triangle at its widest point, projected from breakout
[FORMULA] Target = Breakout Price ± Triangle Height (at widest point)
[EXAMPLE] Ascending triangle with resistance at $100 and support rising from $80 to $95. Triangle height = $100 - $80 = $20. Breakout above $100 targets $120.
### Breakout Timing
[KEY] Breakouts typically occur between 50-75% of the distance to the apex. Breakouts very close to the apex tend to be less reliable and have weaker moves.
### Volume Pattern
**Ideal volume behavior:**
- Volume contracts as triangle forms
- Volume expands on breakout
[WARNING] Low volume breakouts often fail. The breakout should show conviction—ideally volume 50%+ above average.
### False Breakouts
Triangles can produce false breakouts where price breaks one direction then reverses:
**Protection strategies:**
- Wait for close outside triangle (not just intraday)
- Require volume confirmation
- Use stop-loss inside triangle
- Consider waiting for retest of breakout level
[EXERCISE] A symmetrical triangle shows highs at $58, $56, $54 and lows at $48, $50, $52. Price breaks above the upper line at $55 on heavy volume. What's your target? |ANSWER| Triangle height at widest = $58 - $48 = $10. Target = $55 + $10 = $65. The symmetrical triangle gave no directional bias, but the upside breakout with volume suggests buying pressure.
[SCENARIO] You identify an ascending triangle with 5 touches of resistance at $75. Price breaks above $75, you buy at $76. The next day, price falls back inside the triangle, closing at $73. What do you do?
This is a failed breakout. Exit immediately—the pattern failed and there's no reason to hold. Your stop should have been triggered (placed inside the triangle, perhaps around $72). Don't wait and hope; failed breakouts often lead to moves in the opposite direction.
