Dynamics

"The trend is your friend, but only if you know its strength." Unknown

Dynamics indicators measure trend strength, speed, and direction. Unlike momentum indicators that measure rate of change, dynamics indicators answer: "Is there a trend, and how strong is it?" Critical for filtering signals and avoiding whipsaws in ranging markets.
