How you use the Fibonacci Gann projections? The projections change and projections retrace? Are the zig-zag lines non predictive? Like the zig-zag indicator which helps clarify past swings but not helps to forecast the future?
I use fibs to come up with target projections. If it is an abc correction, the C wave will make it to the 100% level. If it is the start of a new trend the wave three will hit the 161.8 level. I never stay in to find out if their will be a fourth or fifth wave because the fifth wave is too unreliable.
re. Zig-Zag: you need one that shows price range of each swing. See www.janarps.com "Universal Swing Tool", it's free. See free fib. videos: Carolyn Boroden: www.syncmt.com Mark Braun: www.mjbraun.net They are into extensions & projections...and swing symmetry.
