AUD/USD’s decline last week suggests that corrective rise from 0.6677 has completed with three waves up to 0.6894. Initial bias remains on the downside this week for retesting 0.6677 low first. Break will resume larger down trend. On the upside, above 0.6808 minor resistance will turn intraday bias neutral first. But risk will stay on the downside as long as 0.6894 resistance holds.
In the bigger picture, decline from 0.8135 (2018 high) is seen as resuming the long term down trend from 1.1079 (2011 high). Next target is 0.6008 (2008 low). On the upside, break of 0.7082 resistance is needed to be the first sign of medium term bottoming. Otherwise, outlook will remain bearish even in case of strong rebound.
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. Sustained break of 0.6826 will target 0.6008 low and then 61.8% projection of 1.1079 to 0.6826 from 0.8135 at 0.5507.
