The power of Fibonacci n"ver stops. A harmonic scan often generates strong pitchforks due to the level of "Fibonacci-ness" in the primary swing. The advantage of the fork being that it goes beyond what a trend line can do, in that it projects predictive bounces where trend lines cannot yet be drawn. In this instance (and yes, they don't always work ... but then, I only trade them when they do, LOL), the Scan's reversal at D is met by the pitchfork's median. Forks are also great for secondary entries into the channel move, as well as money management.
