Pattern
Diagonal
A motive pattern with overlapping waves that forms a wedge shape. Leading diagonals appear in Wave 1 or Wave A position; ending diagonals appear in Wave 5 or Wave C position. Both subdivide into five waves (3-3-3-3-3).
EXAMPLE
An ending diagonal in Wave 5 shows converging trendlines with each sub-wave being a three-wave structure, signaling the final exhaustion of the trend.
