Triangles: Ascending, Descending, Symmetric
Price coiling into a point — a spring that eventually releases. Which way?
Triangles form when price swings get smaller over time, coiling toward a point as buyers and sellers reach a temporary balance. The three flavours differ in who’s applying pressure.
- Ascending triangle — a flat top (resistancePrice zones where buying (support) or selling (resistance) tends to dominate.) with rising lows. Buyers keep stepping in higher while sellers defend one ceiling. Pressure building upward; usually breaks up.
- Descending triangle — a flat bottom (supportPrice zones where buying (support) or selling (resistance) tends to dominate.) with falling highs. Sellers keep pressing lower while buyers defend one floor. Pressure building downward; usually breaks down.
- Symmetric triangle — both lower highs and higher lows, coiling evenly. A pure tightening with no built-in bias; trade the breakoutWhen price decisively pushes through a support or resistance level. direction.

The shape tells you who’s winning the squeeze: in an ascending triangle, rising lows mean buyers are growing impatient and willing to pay more, while sellers hold a single line that eventually cracks.

FAQs
Can an ascending triangle still break downward?
Yes — the lean is a probability, not a law. Ascending triangles *usually* break up and descending ones down, but markets fake out. That’s why you wait for the actual break (ideally on volume) and use a stop, rather than front-running the “expected” direction.
