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.
Historical replay numbers are unavailable because the artifact is stale (source bars are 15 days old). The page does not substitute zeros or older results.
How this is measured →Setup Criteria
- › Sharp 'flagpole' advance of 20%+ in 1–4 weeks
- › Flag retraces no more than 50% of the pole
- › Volume contracts significantly during flag
- › Pattern duration typically 1–4 weeks
- › Parallel upper and lower trendlines on the flag
Breakout above the upper trendline of the flag on heavy volume.
Below the lowest bar of the flag.
