Broadening Phase: The first half of the pattern must show at least two higher highs and two lower lows with diverging trendlines.
Narrowing Phase: The second half must show lower highs and higher lows with converging trendlines, creating the rhombus shape.
Breakout Confirmation: A decisive close above the descending resistance line on the right side of the diamond, ideally on high volume.
