The aussie found strength to push back after five attempts at the 0.6680 support zone. It seems buyers have regained control for now. The first upside impulse was met with more buying interests at the 61.8% (0.6710) Fibonacci retracement level. What is happening now could be the fourth corrective wave and we can expect the area around 0.6730 and the lower band of the rising channel to offer support.
