AUD/USD edged higher to 0.6536 but quickly retreated. Still, downside is contained by 0.6406 support so far. Initial bias remains neutral this week, and further rise is mildly in favor. Above 0.6536 will resume the rally from 0.5913 to 61.8% retracement of 0.6941 to 0.5913 at 0.6548. However, firm break of 0.6406 will confirm short term topping, and turn bias back to the downside for 38.2% retracement of 0.5913 to 0.6536 at 0.6298.
In the bigger picture, AUD/USD is still struggling to sustain above 55 W EMA (now at 0.6441) cleanly, and outlook is mixed. Sustained trading above 55 W EMA will indicate that rise from 0.5913 is at least correcting the down trend from 0.8006 (2021 high), with risk of trend reversal. Further rise should be seen to 38.2% retracement of 0.8006 to 0.5913 at 0.6713. However, rejection by 55 W EMA will revive medium term bearishness for another fail through 0.5913 at a later stage.
In the long term picture, fall from 0.8006 is seen as the second leg of the corrective pattern from 0.5506 long term bottom (2020 low). Hence, in case of deeper decline, strong support should emerge above 0.5506 to contain downside to bring reversal. On the upside, firm break of 0.6941 will argue that the third leg has already started back to 0.8006.
