Diamond Top and Bottom Pattern

The diamond pattern is a rare but significant reversal formation. It combines a broadening formation followed by a symmetrical triangle, creating a diamond or rhombus shape. When it appears at market tops, it's called a diamond top (bearish); at bottoms, it's a diamond bottom (bullish). The pattern represents a period of increasing then decreasing volatility before a directional move.

Diamond Top and Bottom FAQs

Common questions about the diamond top and bottom pattern

The diamond pattern is one of the rarest chart patterns. It's much less common than head and shoulders, triangles, or flags. When it does appear, it tends to be significant because it reflects a complex shift in supply and demand dynamics.

A diamond top forms after an uptrend and signals a bearish reversal. A diamond bottom forms after a downtrend and signals a bullish reversal. The pattern structure is the same; the context (preceding trend) determines whether it's a top or bottom.

While possible, diamond patterns are most reliable on daily and weekly charts. On intraday timeframes, the pattern may be noise rather than a genuine formation. Higher timeframes give the pattern more credibility.
