AUD respects the 88.6 fib ratio number. If you put AUDUSD on a high time frame chart you will see what I mean and it works in all the AUD crosses as well.
On Monday I posted a chart of the monthly AUDCAD chart showing that AUDCAD looked to have broken up above long term resistance that I was watching for a sell signal. Weaker than expected CPI numbers tonight for Australia has sent this pair shanking and it now does look like a neat short setup. A rejection at the 88.6fib (2004 highs to 2008 lows) and the big trendline and two equal corrective swings off the 6 June lows.
