Reversal Patterns
Head and Shoulders Top
A three-peak reversal pattern that forms at the end of an uptrend, where a higher middle peak (the head) sits between two lower, roughly equal peaks (the shoulders), separated by a support line called the neckline.
Inverse Head and Shoulders
The mirror image of the head and shoulders top: a three-trough reversal pattern that forms at the end of a downtrend, where a deeper middle trough (the head) sits between two shallower, roughly equal troughs (the shoulders).
Double Top
A bearish reversal pattern shaped like the letter "M": price rallies to a peak, retreats to a support level, rallies again to a similar peak, then fails and breaks the support.
Double Bottom
A bullish reversal pattern shaped like the letter "W": price falls to a trough, bounces to a resistance level, falls again to a similar trough, then breaks above the resistance.
Triple Top
A bearish reversal pattern in which price tests the same resistance level three times without breaking through, then finally breaks down through the support formed by the intervening troughs.
Triple Bottom
A bullish reversal pattern in which price tests the same support level three times without breaking down, then finally breaks up through the resistance formed by the intervening peaks.
Rounding Bottom
A gradual, saucer-shaped bullish reversal pattern in which a decline slowly loses momentum, flattens into a broad bottom, and then slowly curves back upward before breaking above the level where the decline began.
Rounding Top
The mirror image of the rounding bottom: a gradual, dome-shaped bearish reversal in which an advance slowly loses momentum, flattens into a broad top, and then slowly curves downward before breaking below the level where the advance began.
Rising Wedge
A bearish pattern in which price rises inside a narrowing channel — both the highs and the lows are rising, but the lows rise faster than the highs, converging toward an apex before breaking down.
Falling Wedge
A bullish pattern in which price falls inside a narrowing channel — both the highs and the lows are falling, but the highs fall faster than the lows, converging toward an apex before breaking up.
Diamond Top
A rare bearish reversal pattern combining a broadening formation and a symmetrical triangle back to back: swings widen into a rhombus shape, then narrow toward an apex before breaking down.
Diamond Bottom
The mirror image of the diamond top: a rare bullish reversal pattern in which swings widen into a rhombus shape after a downtrend, then narrow toward an apex before breaking up.
Continuation Patterns
Cup and Handle
A bullish continuation pattern that looks like a teacup in profile: a rounded "cup" retracement back to the prior high, followed by a shallow "handle" pullback, then a breakout above the cup's rim.
Ascending Triangle
A bullish continuation pattern formed by a flat resistance line at the top and a rising trendline of higher lows at the bottom, converging toward the resistance level.
Descending Triangle
A bearish continuation pattern formed by a flat support line at the bottom and a falling trendline of lower highs at the top, converging toward the support level.
Bull Flag
A short bullish continuation pattern consisting of a sharp, near-vertical advance (the "flagpole") followed by a brief, gently downward-sloping consolidation (the "flag") before the advance resumes.
Bear Flag
A short bearish continuation pattern consisting of a sharp, near-vertical decline (the "flagpole") followed by a brief, gently upward-sloping consolidation (the "flag") before the decline resumes.
Bullish Pennant
A short bullish continuation pattern consisting of a sharp advance (the "flagpole") followed by a brief, small symmetrical-triangle consolidation before the advance resumes.
Bearish Pennant
A short bearish continuation pattern consisting of a sharp decline (the "flagpole") followed by a brief, small symmetrical-triangle consolidation before the decline resumes.
Bilateral Patterns
Symmetrical Triangle
A bilateral pattern formed by a falling trendline of lower highs and a rising trendline of higher lows, converging toward an apex. Unlike ascending or descending triangles, it carries no inherent directional bias.
Rectangle
A bilateral trading-range pattern bounded by a flat resistance line above and a flat support line below, in which price oscillates repeatedly between the two before eventually breaking out in either direction.
Broadening Formation
A bilateral "megaphone" pattern in which each swing high is higher and each swing low is lower than the one before — the trading range expands rather than contracts, the opposite of a triangle.
