Bull Flag Setup
A tight, orderly pullback after a sharp vertical advance. The flag trades sideways or slightly downward on declining volume, then resolves with a breakout that continues the prior uptrend.
Target before stop: 19% reached +20% before −8% within 40 sessions. Sample: n=37 eligible setups. Average: +0.9% per setup (+0.11R).
Source-bar window: 2024-11-01–2026-10-26. Entry requires an executable breakout fill after the signal; unresolved setups receive the full replay window. Historical and illustrative, not predictive. No brokerage slippage, fees, taxes, or individualized sizing.
