AUD/USD rose to 0.7031 last week be reversed from there. The breach of 0.6938 resistance turned support suggests short term topping. Initial bias is mildly on the downside this week for 1.6838 support first. Break will target 0.6754 near term structural support next. On the upside, though , break of 0.7031 will resume the corrective rebound from 0.6670 to 0.7082 key resistance.
In the bigger picture, with 0.7082 resistance intact, there is no clear confirmation of trend reversal yet. That is, down trend from 0.8135 (2018 high) is still expect to continue to 0.6008 (2008 low). However, decisive break of 0.7082 will confirm medium term bottoming and bring stronger rally back to 55 month EMA (now at 0.7506).
In the longer term picture, prior rejection by 55 month EMA maintained long term bearishness in AUD/USD. That is, down trend from 1.1079 (2011 high) is still in progress. Next downside target is 61.8% projection of 1.1079 to 0.6826 from 0.8135 at 0.5507.
