AUDUSD is facing the support of the upward trend line on 4-hour chart, a clear break below the trend line support will indicate that the uptrend from 1.0287 has completed at 1.0515 already, then the following downward movement could bring price back to 1.0000 zone. On the upside, as long as the trend line support holds, the fall from 1.0515 could be treated as consolidation of the uptrend, and one more rise to 1.0550 area is still possible.
