Chart Patterns That Work: Triangles, Flags, and Wedges

Chart patterns are recurring price formations that appear because human psychology is consistent — fear and greed manifest in similar ways across markets and timeframes. Understanding the psychology behind each pattern helps you evaluate its reliability rather than mechanically trading every formation you see.
Flags and Pennants
Flags and pennants are continuation patterns: brief consolidations after a sharp move, before the trend resumes. A bull flag shows a strong up move (the pole), followed by a tight, downward-sloping channel (the flag), then a breakout continuation. The measured move target is the pole length projected from the breakout. Flags work best in strongly trending markets with decreasing volume during the consolidation.
Triangles and Wedges
Symmetrical triangles represent compression — neither buyers nor sellers winning — and typically break in the direction of the prior trend. Ascending triangles (flat top, rising bottom) signal buyer aggression and typically break upward. Wedges are trickier: a rising wedge in an uptrend is actually bearish (weakening buyers), while a falling wedge is bullish. Always confirm pattern breaks with volume and wait for a close outside the pattern before entering.
