Symmetrical Triangle Pattern

A 1-minute lesson from the MarketPro academy, one of 22 in chart patterns.

Short answer

A symmetrical triangle forms when a series of lower highs and higher lows converge toward a point, reflecting a period of contracting volatility as buyers and sellers reach a temporary equilibrium. Unlike ascending or descending triangles, neither boundary line is flat; both slope toward each other, which means the pattern gives less directional bias on its own and is often treated as a pause within the prevailing trend rather than a strong reversal or continuation signal by itself.

Contracting range: Price swings become progressively smaller as the pattern develops, often alongside declining volume.
Breakout direction: Because the pattern is directionally neutral in shape, many traders lean on the preceding trend, or wait for a confirmed breakout with supporting volume, before assuming a direction.
Apex timing: Symmetrical triangles often resolve with a breakout before price reaches the apex, though there is no fixed rule for exactly when.

Because the pattern can break in either direction, treating it as a signal to prepare for increased volatility, rather than as a prediction of direction, is a more balanced way to approach it.
