AUDUSD broke above the upper line of the price channel on 4-hour chart. However, the rise from 0.8820 is likely consolidation of the downtrend from 0.9756 (Oct 23, 2013 high). Resistance is now at 0.9040, as long as this level holds, the downtrend could be expected to resume, and another fall towards 0.8500 is possible. Only break above 0.9040 resistance could signal completion of the downtrend.
