AUD/JPY New Idea Using FIB Retrace Tool

I have been experimenting with the FIB retrace tool and this is my idea. The move up from 19th March has completed the top. The retrace is underway but how far will it fall. I have used the FIB tool to project a possible end by placing the 76.4% line at a place where I think it fits. This then puts the projected fall to the 50% fib line of the initial move up. I am interested to see how this pans out.
