The chart has to be scaled carefully to make this work. EURUSD, AUDUSD and NZDUSD all use arc swings. In fact I haven't seen any stock or currency that doesn't...especially in consolidation type of movement. If there are steep up or down moves then the other ratios are combined with the 1 arc. .874 and .764 are the 2 I like. Also look for .874 to 1 and then to 1/.874 or inverse. The 1 ratio in between. Obviously you would want to combine this idea with others to improve the accuracy for prediction. I use channels and sometimes angles. The problem with predicting is when too many possibilities exist for ratios. That's what I like about setting up single swing arcs that catch 2 points on the swing. Test it out and see how it works for you. In practice first. I think it's going up for another day or 2 before it drops.
