Symmetrical Triangle Pattern
A symmetrical triangle forms when highs fall and lows rise into a single point. It is a coiling pattern with no built-in direction — the break decides.
A symmetrical triangle forms when the highs keep getting lower and the lows keep getting higher at roughly the same rate. Draw a line along each and they converge on a point. What it shows is a market coiling: sellers are willing to accept less each time, buyers are willing to pay more each time, and the range available to both is shrinking.
Unlike the ascending and descending triangles, this one carries no built-in direction. Neither side is winning; they are simply running out of room. That makes it the purest of the three as a volatility signal and the least useful as a directional one. The break decides, not the shape.
Trading the Break
Volatility contracts and then expands — that is the whole thesis. As the apex approaches, the daily range narrows and volume usually dries up, which is why a symmetrical triangle often shows up on a TTM squeeze scan at the same time. The resolution tends to be sharp because positions on both sides are clustered tightly together, and one of them is about to be wrong all at once.
Two failure modes are worth knowing. Price that drifts all the way to the apex without breaking usually dribbles out rather than exploding — the energy dissipates. And the first break is frequently false, especially on a low-float stock where a small order can push price through a line that nobody was defending.
What to Watch For
- No directional bias — it signals a coming move, not which way.
- Volatility contracts into the apex and expands out of it.
- Price that reaches the apex without breaking usually fizzles rather than explodes.
- First breaks are often false on low-float stocks.
