Pennant Setup
A symmetrical triangle that forms after a strong price advance, with converging trendlines on both sides and contracting volume. Unlike a full symmetrical triangle, a pennant is small and brief — a 1–4 week pause in an ongoing trend. It resolves with continuation of the prior move.
Sample still building: 2 eligible setups in the 2024-11-01–2026-10-26 source-bar window. Rates stay hidden until n=30. Historical and illustrative, not predictive.
