New high trends may end in a few bars or last for
years. But as impulse and reaction carve out the
uncharted territory, familiar features start to
emerge. Elliott's Rule of Alternation offers one
important lesson when rallies thrust upward into new
prices. He notes that congestion patterns formed
between rally impulses tend to alternate between
simple and intricate shapes. And complex congestion
takes longer to resolve than simple reactive
movement.
