Chart Patterns 101: Triangles, Flags, and Head & Shoulders Explained
BullBearStock Editorial
March 6, 2026
Classical chart patterns still work—if you respect context. Learn how to trade triangles, flags, and head & shoulders with entries, invalidations, and targets.
Why Patterns Persist
Patterns visualize crowd behavior: compression, continuation, and distribution/accumulation. They’re frameworks for planning risk, not crystal balls. Combine them with trend context, volume, and volatility.
Clean sketches: symmetrical triangle, bull flag, head & shoulders (H&S), inverse H&S.
Triangles: Coiling Energy
- Entry: Break of triangle boundary with volume.
- Stop: Opposite side of the pattern or false-break low/high.
- Target: Height of triangle projected from breakout.
Flags: Continuation After Impulse
- Entry: Break of flag channel in direction of prior move.
- Stop: Beyond the opposite flag boundary.
- Target: Prior impulse length measured from breakout.
Head & Shoulders: Reversal Blueprint
- Neckline Break: Confirmation of pattern; volume should expand.
- Stop: Above right shoulder (H&S) or below (inverse H&S).
- Target: Distance head-to-neckline projected from break.

Common Pitfalls
- Forcing patterns in random chop.
- Ignoring higher timeframe trend (countertrend patterns fail more).
- Skipping volume confirmation on breakout.
Pattern Trading Checklist
- Clear structure and boundaries?
- Volume behavior supportive?
- Defined stop and measured target?
- Confluence with levels or moving averages?
