Chart patterns: head and shoulders, double tops, flags

Chart patterns: head and shoulders, double tops, flags

Chart patterns are recognizable price formations that repeat across markets and timeframes, often preceding the same type of move each time. This lesson covers three of the most widely watched — two reversal patterns and one continuation pattern.

Head and shoulders — bearish reversal

The head and shoulders pattern forms at the top of an uptrend and consists of three peaks:

• Left shoulder — an initial high, followed by a pullback
• Head — a higher high (the tallest peak), followed by another pullback to roughly the same level as the first
• Right shoulder — a third peak roughly equal to the left shoulder, followed by a decline

The neckline connects the two pullback lows between the three peaks. The pattern is confirmed — and the reversal signal triggered — when price breaks and closes below the neckline after forming the right shoulder. In the diagram above, watch the three-peak sequence and the final breakdown below the neckline.

The head and shoulders pattern is one of the most reliable reversal patterns, but it's only confirmed on a neckline break — not when the right shoulder forms.

Double top — bearish reversal

A double top is simpler: price reaches a high, pulls back, then returns to approximately the same high and fails to break it. The two equal peaks form a "M" shape. Like head and shoulders, the pattern is confirmed when price breaks below the pullback low (the neckline) between the two peaks — not when the second peak forms.

The double top is essentially the same concept as equal highs forming a liquidity pool from the previous lesson, viewed through a pattern-recognition lens rather than a liquidity lens.

Inverse versions — bullish reversals

Both patterns have inverse versions that signal bullish reversals: the inverse head and shoulders (three troughs with the middle being the lowest) and the double bottom (two equal lows forming a "W" shape). Both confirm on a neckline breakout upward.

Flag — continuation pattern

A flag is a brief consolidation period within a strong trend, forming as a tight, slightly counter-trend channel after a sharp impulsive move. After the consolidation ends, price typically breaks out in the original direction and continues the trend.

The key characteristics of a valid flag:

• A strong, sharp initial move (the "flagpole")
• A tight, relatively brief consolidation that drifts mildly against the trend
• A breakout in the original direction, often targeting the flagpole's length measured from the breakout point

Flags are continuation patterns, not reversals — they're a pause in a trend, not the end of one.

Why pattern location matters more than pattern shape

The same pattern carries very different weight depending on where it forms. A head and shoulders at a major weekly resistance level is significantly more meaningful than the same shape appearing in a sideways choppy range on a lower timeframe. Always combine pattern recognition with your structural analysis — the location gives the pattern its context and credibility.

• Head and shoulders: three peaks (left shoulder, head, right shoulder) — confirmed bearish only on a neckline break, not when the right shoulder forms
• Double top: two equal peaks — confirmed bearish on a break below the pullback low between them
• Both have bullish inverse versions: inverse head and shoulders and double bottom
• A flag is a continuation pattern — a brief tight consolidation after a strong move, breaking out in the original trend direction
