Gold is near trendline and 200d MA support - so unless it breaks down like the other commodities, it could be a good bet. At the very least it should bounce from here.
Sept can be a scary month. Certainly this Sept fits the bill. When this is the case, October is often when an important bottom is made. The problem is we don't know from what level - and right now, there are no technical signs of a bottom yet. Canadian dollar is weak simply because it's a commodity currency much like the Aussie dollar. I think the loonie might bottom around .93-.94 (last year's low). Everything else seems to be going there, too.
