AUD/USD drew strong support above 0.8066 low and rebounded sharply last week. Further rise could still be seen initially this week and breach of 0.8549 resistance is possibly. But we'd expect strong resistance near to 0.8715 (50% retracement of 0.9380 to 0.8066 at 0.8723) to conclude the whole consolidation pattern fro 0.8066 and finally bring down trend resumption. Below 0.8355 minor support will flip intraday bias back to the downside for retesting 0.8066 support first.
In the bigger picture, while the decline from 0.9380 is steep, it's still treated as a correction to medium term up trend from 0.6008. Hence, we're expecting strong support from 0.7702 (50% retracement of 0.6008 to 0.9404 at 0.7706), at least initially, to bring rebound. But after all, decisive break of 0.8715 support turned resistance is needed to indicate that fall from 0.9380 is completed. Otherwise, more downside would remain in favor.
In the longer term picture, long term correction from 0.9849 has likely completed at 0.6008 already, after being supported slightly above 76.4% retracement of 0.4773 (01 low) to 0.9849 (08 high). Rise from 0.6008 is possibly developing into a new up trend which extend the long term rise from 0.4773. We'll continue to favor the long term bullish case as long as 0.7702 support holds and expect an eventual break of 0.9849 high. However, a break of 0.7702 support will firstly argue that whole rise from 0.6008 has completed. Secondly this will open up the case that AUD/USD is in phase of a long term consolidation and will gyrate in the large range of 0.6008/0.9849 for some time.
