AUD/USD breakdown underway after long hibernation?

AUDUSD looks to be breaking neckline support at 0.6837, which may set the stage for a test of downside thresholds at 0.6765 and 0.6678. Near-term, neutralizing selling pressure might demand re-establishing a foothold above 0.6872. From there, another challenge of the 0.70 figure could follow.
