Don't know if it's right, but it sure looks copastetic. This center is chosen because the other arcs line up that way. Arcs are radius distance measurements. All the angles point to that spot. I predict a really vertical acceleration because of the wedge coming down also and it correlates with others like NZDUSD. They'll probably pop together. I've found when everything looks perfect, something messes up though. It's always harder to predict with perfection than waiting for a moving average to tell you it's a reversal after 1/2 the move is finished.
