AUD/USD Set to Complete Topping Pattern?

AUD/USD broke below the long-standing 0.7664-91 support zone, seemingly opening the door for a run at the neckline of a large Head and Shoulders topping pattern (0.7564). A daily close below that would imply a measured move lower toward the 0.71 figure. A notable hurdle is eyed near the 0.74 mark along the way.
