Chart Patterns That Actually Work

Continuation patterns form when a trending market pauses to consolidate before continuing in its original direction. Understanding why they form — and what distinguishes high-probability setups from noise — is the key to trading them profitably. The bull flag is the most reliable continuation pattern. After a strong, nearly vertical move up (the flagpole), price consolidates in a tight, slightly downward channel (the flag). Volume contracts during the flag — this is critical. The breakout of the upper channel boundary, ideally with a volume expansion, signals the continuation. Measured move target: add the flagpole height to the breakout point. The bear flag is the mirror: sharp move down, consolidation in a slightly upward channel, breakout of the lower boundary. What makes a high-quality flag: the flagpole should be steep (45+ degree angle, often created by a news event or significant momentum shift), the consolidation should be tight (small range relative to the flagpole), volume should notably contract during the flag, and the pattern should resolve within 5-20 bars of the initial move. Flags that take 50+ bars to resolve are often not flags — they're range-bound markets. Pennants are similar but consolidate in converging triangles rather than channels. The consolidation is more symmetric. Same rules apply: steep pole, volume contraction in the pennant, volume expansion on breakout. Wedges are consolidation patterns with converging trend lines, both sloping in the same direction. A rising wedge is bearish (price compressing upward but losing momentum), a falling wedge is bullish. Wedges are typically longer-term patterns than flags and require more bars to form. The breakout of a wedge often produces a sharp, swift move.

Reversal patterns signal the end of a trend and the beginning of a move in the opposite direction. They are less common than continuation patterns and require more confirmation before trading. Head and Shoulders (H&S): three peaks where the middle peak (head) is higher than the two surrounding peaks (shoulders), connected by a neckline drawn across the two valleys. Classic formation at market tops after extended uptrends. The break of the neckline triggers the short, with a measured move target equal to the height from the head to the neckline, projected downward from the neckline break. Key H&S characteristics: the right shoulder should be roughly symmetrical with the left shoulder in both time and price. Volume typically peaks on the left shoulder, is lower on the head, and lowest on the right shoulder — declining volume on each push to new highs signals weakening buying pressure. Failed H&S (price breaks above the right shoulder) is often a powerful long signal — trapped sellers cover aggressively. Inverse H&S is the bullish mirror: three troughs with the middle trough (head) being lower, neckline resistance above the two shoulders. Common at major market bottoms. Cup and Handle: a U-shaped consolidation (the cup) followed by a brief pullback (the handle), then a breakout above the rim of the cup. The cup should be rounded (not V-shaped), the handle should be a mild pullback (no more than 50% of the cup's depth), and volume should expand significantly on the breakout. This pattern often appears on longer-term charts (weekly/monthly) and can precede sustained multi-month rallies. The most critical rule for all reversal patterns: wait for the break and, ideally, the retest before entering. Many patterns fail. The confirmation step filters out false signals.
