AUDUSD is facing the support of the upward trend line on 4-hour chart. As long as the trend line support holds, the uptrend from 0.7369 could be expected to continue, and next target would be at 0.7600 area. However, a clear break below the trend line support will indicate that the uptrend had completed at 0.7508 already, then the following downward movement could bring price back to test 0.7310 support.
