Utilizing a Sentient Trader organic analysis of the AUD/USD currency pair starting at the December 1996 high, it appears that the Aussie is headed down into a large cluster of cycle troughs, the largest of which is at least of the 18-month variety. Inside that cluster of troughs, the 26.4 week cycle is expected now within the fairly narrow date range of November 27 through December 11.
Further support of the idea that a major low is near is my Elliott Wave count below, which shows that the movement down from the July 2011 top is clearly corrective, and appears to be nearly finished with a complex WXYXZ correction.
The daily chart shows a bit more detail . .
To conclude, based on the combination of Sentient Trader’s Hurst cycle analysis, and my own Elliott Wave count and associated Fibonacci price targets, I believe the Aussie is likely to bottom in the next couple of days at about .8352 as shown on the 240-minute chart below.
