AUD/USD rebounded from 0.7450 (38.2% of Jan low – Apr high) in late July (once is an accident) …then again mid September (twice is coincidence) and now it is closing-in on the key level again.
Thrice may not happen at all! This is because the pair is coming off a repeated failure near 0.78 handle followed by a break of the rising trendline/symmetrical triangle.
