Symmetrical Triangle: Breakout Trading Guide

Coil and release

A symmetrical triangle is the market compressing. Lower highs and higher lows converge into a point. Volatility drops. Then eventually one side wins and you get a strong breakout — often on a large volume bar that ends the indecision.

Trading it

Because symmetrical triangles are directionally neutral, you don't pre-position. You wait for the break, enter on confirmation, stop inside the triangle, target the measured move (triangle height). Breakouts against the prior trend have lower hit rates than breakouts in the direction of the prior trend — that's the only directional edge.

Failed breakout playbook

The most common failure: breakout, retest, fail. If price breaks up, pulls back to the triangle apex, and then closes back inside the triangle, that's a failed breakout and often a high-probability trade in the opposite direction.
