Symmetrical Triangle

A symmetrical triangle forms when price makes lower highs and higher lows at roughly the same rate, so two converging trend lines meet at a point called the apex. It shows a market in balance, with swings getting smaller as buyers and sellers wait. Unlike ascending and descending triangles, it has no built in bias. It more often breaks in the direction of the trend that came before it, but either direction is possible.

Anatomy#

What it means#

The triangle is a picture of compression: volatility shrinks as the range narrows. Buyers keep stepping in at higher lows and sellers keep stepping in at lower highs, until one side gives way. Because orders build up above and below the pattern, the breakout often comes with a burst of volatility. See Compression and Expansion.

Trading the breakout#

1. Draw both lines through clear swing points.
2. Note the prior trend: a symmetrical triangle in an uptrend more often breaks upward, and vice versa.
3. Wait for a close beyond a line, ideally with rising volume.
4. Entry: on the close, with a stop order just outside the line, or on a retest.
5. Stop: inside the triangle, beyond the most recent swing on the other side.
6. Target: measure the height at the widest part of the triangle and project it from the breakout point.

Where breakouts happen#

Many analysts note that the most reliable breakouts occur roughly two thirds to three quarters of the way to the apex. If price wanders all the way to the apex without breaking, the pattern loses its meaning and the eventual move is less predictable.

Handling false breakouts#

Symmetrical triangles are prone to false breaks, especially wicks through a line that close back inside, or a break in one direction followed by a fast reversal the other way. Ways to manage this:

• Require a candle close beyond the line, not just a wick.
• Look for volume expansion on the break.
• Exit quickly if price closes back inside the triangle.
• Consider trading the reversal after a clear failure. See Failed Breakouts and False Breaks.

Symmetrical triangle vs pennant#

A pennant is a small symmetrical triangle that forms right after a sharp move, usually lasting only a few candles. A symmetrical triangle can be larger and take weeks or months. See Pennants.

Common mistakes#

• Predicting the direction before the break without evidence.
• Trading every small triangle on very low timeframes.
• Placing stops too tight inside a pattern that is still swinging.

Frequently asked questions#

Is a symmetrical triangle bullish or bearish?#

Neither by itself. It often breaks in the direction of the prior trend, but traders should wait for the breakout to confirm.

How do you trade a symmetrical triangle?#

Wait for a close beyond one of the converging lines, enter with a stop inside the pattern and use the triangle's height for a target.

What is the apex of a triangle?#

The point where the two converging trend lines meet. Breakouts usually happen before price reaches it.
