This is different than the other similar xagusd. I wouldn't trust it. It's an experiment in anchoring with the fib circle and it just so happened that the key point in the middle also worked out to be very close to the proper center. Supposedly the arc should swing around and the points should hit somewhere on them (key points). Experiment with it yourself if you want and pass on any good news if it works. Just "make it mine" upper right arrow on the chart if you want to work with it.
