Diamond Top Complete Guide
What is Diamond Top?
The Diamond Top is a bearish reversal chart pattern that typically forms at the peak of an extended uptrend, signaling a potential shift from bullish to bearish sentiment. Visually, it resembles a diamond shape, formed by a broadening price pattern that then transitions into a contracting pattern. Initially, price swings widen, characterized by higher highs and lower lows, indicating increasing volatility and indecision among market participants. This broadening phase suggests a struggle between buyers and sellers, with neither side firmly in control. Subsequently, the price action begins to contract, forming lower highs and higher lows, as volatility subsides and the trading range narrows. This transition from expanding to contracting volatility creates the distinct diamond shape. The pattern is confirmed when the price breaks below the lower trendline of the diamond, often accompanied by a significant increase in volume, signaling the start of a new downtrend. According to Thomas Bulkowski's 'Encyclopedia of Chart Patterns,' the Diamond Top is a highly reliable reversal pattern, ranking among the best performers for bearish breakouts, with an average post-breakout decline of approximately 19% and a relatively low failure rate of around 10%. Volume typically shows an initial increase during the broadening phase, followed by a decline as the pattern narrows, and then a sharp spike on the downside breakout.
Identification Rules
- A clear, established uptrend must precede the formation of the Diamond Top pattern.
- The pattern begins with a broadening formation (higher highs and lower lows), indicating increasing volatility and indecision.
- The broadening phase transitions into a contracting phase (lower highs and higher lows), forming the distinct diamond shape.
- Confirmation occurs when the price breaks decisively below the lower trendline of the diamond, ideally with increased volume.

FAQ
What does the diamond shape signify in terms of market psychology?
The diamond shape reflects a period of intense indecision and increasing volatility, followed by a decrease in volatility. The initial broadening suggests a loss of control by bulls and growing bearish influence, while the subsequent contraction indicates a temporary equilibrium before the bears ultimately gain control and push prices lower.
How reliable is the Diamond Top pattern as a reversal signal?
According to Thomas Bulkowski's extensive research, the Diamond Top is considered a highly reliable bearish reversal pattern. It ranks among the top performers for bearish breakouts, with a historical failure rate of approximately 10% and a strong tendency for prices to decline significantly after the breakout.
What is the typical price target after a Diamond Top breakout?
A common method for estimating the price target is to measure the widest vertical distance of the diamond pattern and project that distance downwards from the breakout point. Bulkowski's data suggests an average post-breakout decline of around 19%.
How does volume typically behave during the formation and breakout of a Diamond Top?
Volume often increases during the initial broadening phase of the diamond, reflecting heightened activity and indecision. As the pattern contracts, volume tends to decline, indicating waning interest. A crucial characteristic is a significant spike in volume on the decisive downside breakout, confirming the bearish reversal.
How does a Diamond Top differ from a Head and Shoulders Top pattern?
While both are bearish reversal patterns, their structures differ. A Head and Shoulders pattern has three distinct peaks (left shoulder, head, right shoulder) with a clear neckline. A Diamond Top, conversely, is characterized by a broadening then contracting price range, forming a diamond shape without the distinct shoulder-head-shoulder structure. The Diamond Top often implies a more complex and volatile period of indecision before the reversal.
