A Diamond Top is a chart pattern formation that is relatively rare. It forms at the conclusion of a long uptrend in price, and it indicates an imminent reversal of the trend.The Diamond Top typically has four distinct phases:1- A prolonged advance in prices, with little volatility and few pullbacks;2- A gradual slowdown in price momentum, accompanied by increasing volatility and volume;3- A sharp price decline leading to the formation of the "diamond" shape on the chart;4- An eventual breakout from the diamond pattern, with prices resuming their previous uptrend or moving lower.
