AUD/USD’s fall from 0.7555 extended lower last week and initial bias stays on the downside this week first. Sustained trading below 55 day EMA (now at 0.7394) will argue that rebound from 0.7105 is complete with three waves up to 0.7555. That would also argue that fall from 0.8006 is ready to resume through 0.7105 low. On the upside, above 0.7470 minor resistance will turn bias back to the upside for 0.7555 resistance again.
In the bigger picture, with 0.6991 cluster support (38.2% retracement of 0.5506 to 0.8006 at 0.7051) intact, we’re seeing price action from 0.8006 as a correction only. That is, up trend from 0.5506 low would resume after the correction completes. In that case, main focus will be 0.8135 key resistance (2018 high). Sustained break there will carry larger bullish implications. However, sustained break of 0.6991 will argue that the whole medium term trend has indeed reversed.
In the longer term picture, focus remains on 0.8135 structural resistance. Decisive break there will argue that rise from 0.5506 is developing into a long term up trend that reverses whole down trend from 1.1079 (2011 high). In that case, further rally would be seen to 61.8% retracement of 1.1079 to 0.5506 at 0.8950 and possibly above. Rejection by 0.8135 will keep long term outlook neutral at best.
