It works well as a directional indicator. I use it if it looks like a nice move will happen but you are unsure what direction. Like a breakout or a false break out, and ORB or a reversal, ABCD, etc. If it bounces right on the 50% or the 61.8% line it has a higher chance of being a reversal or ABCD pull back, etc. It gives me about an extra 10% edge. Which in this game is great.
