AUD/USD retreated ahead of 0.6530 resistance and intraday bias is turned neutral first. On the upside, decisive break of 0.6535, and sustained trading above 55 day EMA (now at 0.6564), will raise the chance of medium term bottoming, and target 0.6680 support turned resistance next. On the downside, below 0.6371 minor support will turn bias back to the downside for retesting 0.6169 low instead.
In the bigger picture, down trend form 0.8006 (2021 high) is expected to continue as long as 0.6680 support turned resistance holds. Medium term momentum remains strong and retest of 0.5506 (2020 low) cannot be ruled out. But firm break of 0.6680 will be the first sign of reversal, and bring stronger rebound back to 0.7135 resistance.
