10 Chart Patterns for Price Action Trading

Chart patterns form over 20–200 bars. Unlike bar patterns (Ch 3) and candlestick patterns (Ch 4), they encode structural intent over a longer time horizon. This chapter covers ten patterns from the price-action reader's perspective — how to spot them forming, when the setup is real, and when it's forced.

The catalog and completion rules also appear in TA Chapter 4. This chapter emphasises the price-action reading — how a discretionary trader identifies and trades these in real time, not after the fact.

5.1 Head & Shoulders (and Inverse)

Three peaks: left shoulder, higher head, right shoulder roughly symmetric with the left. A trendline through the two intermediate lows is the neckline.

• Reading: uptrend prints a new high (head), then fails to hold, then the recovery fails to reach a new high (right shoulder). The failure to make a higher high is the whole signal — buyers are getting exhausted
• Entry: close below the neckline (or short at the right shoulder retest with tight stop)
• Measured move: distance from head to neckline projected downward from the break
• Inverse H&S: mirror at a downtrend bottom, signals bullish reversal

5.2 Double / Triple Top and Bottom

Two (or three) rejections at approximately the same price. The neckline is the intermediate reaction extreme.

• Reading: the market keeps trying to break through a level and keeps failing. Each failed attempt saps momentum
• Failure mode: if the second (or third) touch prints a higher high (top pattern), the pattern is invalidated — often a strong continuation signal
• Volume signature: second peak typically on lower volume (divergence)

5.3 Rounding Top / Rounding Bottom

Slow arc formation over many weeks. No sharp inflections. Rare but very high win-rate when clean.

• Reading: gradual shift from buyer to seller (or vice versa) with no single catalyst — a slow accumulation or distribution
• Trade: position hold, often multi-month. Rarely tradeable intraday

5.4 Island Reversal

A group of bars completely isolated from surrounding price by gaps on both sides. The "island" of bars ends the prior trend.

• Structure: gap in the trend direction → several bars forming a small consolidation → gap in the opposite direction, leaving the middle bars isolated
• Reading: the gap out is the smoking gun. The market fully re-priced and left no volume behind at the extremes
• Rare in India intraday (most Indian indices don't gap much); more common on stock charts with earnings-related gaps

5.5 Rectangle (trading range)

Horizontal support and resistance defining a range. Price oscillates between them for a period.

• Reading: equilibrium — buyers step in at support, sellers step in at resistance. Neither side breaks through
• Trade inside — mean-reversion: buy near support, sell near resistance
• Trade breakout — the bigger trade. When one side finally breaks, measured move = rectangle height projected in the breakout direction
• Statistical bias — ~65% of rectangle breakouts resolve in the direction of the prior trend before the range formed

5.6 Wedge (Rising / Falling)

Two converging trendlines both sloping in the same direction.

• Rising wedge (both lines rising, upper less steep) — bearish. Momentum is running out despite price still rising
• Falling wedge (both lines falling, lower less steep) — bullish. Selling is exhausted despite price still falling
• Counterintuitive — the pattern's expected break direction is opposite to its slope. This traps traders who read it as continuation

5.7 Triangle (Symmetrical / Ascending / Descending)

Converging trendlines forming an increasingly narrow range.

• Symmetrical — lower highs + higher lows. Neutral bias; ~55/45 slight lean to prior trend
• Ascending — flat top + rising lows. Bullish bias (buyers getting more aggressive with each touch)
• Descending — flat bottom + falling highs. Bearish bias
• Reading: volatility contraction. Regardless of direction, an expansion is coming
• Timing: best breaks come before the apex; breaks at or beyond the apex are often exhausted

5.8 Flag / Pennant

Sharp move ("flagpole"), then tight consolidation ("flag" = parallel channel, "pennant" = small triangle).

• Reading: the market caught its breath after a big move. The consolidation is short (5–15 daily bars, 20–60 intraday bars) and orderly
• Entry: break in the direction of the flagpole
• Measured move: flagpole length projected from the breakout
• Failure mode: if the flag deepens past 50% of the flagpole, the continuation thesis is dead

5.9 Cup & Handle

Bullish continuation. Rounded "cup" over weeks/months, followed by a smaller downward "handle" consolidation. Break above the handle high = entry.

• Cup depth ideally 15–30% of the prior uptrend; deeper cups have lower success rate
• Handle should retrace ≤ 30–50% of the cup depth
• Volume dries up in the handle and expands on the break — this is the confirmation

5.10 The price-action edge on chart patterns

Most retail traders use chart patterns as recognition templates — "this looks like a triangle, so I'll trade the break." Price-action readers use them differently. They watch for:

• Volume signature agreement — pattern-appropriate volume behaviour through formation and break
• Higher-timeframe alignment — trade breakouts only when they're aligned with the higher-timeframe trend
• Level context — is the pattern completing at a broader structural level (multi-month S/R, round number)?
• Retest entry — take entries on the retest of the broken level, not the initial break. Lower win rate on trigger, higher win rate per trade

A pattern with all four aligned is high-conviction. A pattern lacking any of them is either "wait" or "skip" — regardless of how textbook the shape looks.
