The Symmetrical Triangle is a neutral chart pattern formed by two converging trend lines that slope toward a central apex — one line descending (lower highs) and one ascending (higher lows). Price oscillates between them in progressively tighter swings. The pattern signals indecision and compression of volatility before a decisive move. Breakout direction typically follows the prior trend, making it most commonly a continuation pattern.

How to Identify

• Upper resistance line slopes downward — connecting at least two lower highs
• Lower support line slopes upward — connecting at least two higher lows
• Both lines converge toward an apex, typically 2–4 weeks ahead of the breakout
• Price swings narrow progressively — each bounce covers less range than the previous
• Minimum two touches per line; three or more greatly improves reliability
• Volume contracts steadily as price compresses — a key confirmation of valid formation
• Breakout ideally occurs 50–75% of the distance to the apex (too late = weak signal)
• Volume should surge sharply on the breakout candle
• Price target: measure the widest height of the triangle and add/subtract from the breakout point

Why It Matters in Current Markets

The symmetrical triangle appears frequently at inflection points — before major index breakouts, after earnings-driven volatility, or during sector rotation pauses. It is one of the most important patterns to recognize because the eventual breakout is often large relative to the compressed range. In uncertain macro environments, these coiling patterns precede both strong rallies and sharp sell-offs.

The direction of the prior trend is your primary bias: an uptrend into a symmetrical triangle typically breaks upward; a downtrend typically breaks downward. However, confirmation from the breakout direction always overrides trend assumptions.
