AUD/USD broke above the falling trend line on the 4-hour chart and extended its upside movement from 0.6754 to as high as 0.6825. As long as 0.6800 support holds, the upside movement could be expected to continue and next target would be at 0.6870 area. Only a breakdown below 0.6800 support would indicate that the uptrend is complete, then another fall towards 0.6750 could be seen.
