Reversal Patterns
Continuation Patterns
Reversal vs. Continuation
Signal that the current trend is losing strength and price is likely to change direction. Head and shoulders, double tops/bottoms, and triple tops/bottoms fall into this category — they form at trend extremes, not in the middle of a move.
Signal a temporary pause in the existing trend before it resumes in the same direction. Triangles, flags, pennants, and wedges fall into this category — they're brief consolidations, not reversals, so context matters more than the shape alone.
Almost every chart pattern relies on the same confirmation rule: volume should contract during the pattern's formation and expand sharply on the breakout or breakdown. A pattern that breaks on low volume is far more likely to fail or reverse.
