I understand your analysis (though not know the reasoning), but I am really bearish on Dollar Index (at least in the short term). I believe the dollar index will make either a double top/ trouble top (which means the highest is around 100) or make a head-shoulder (which means the highest is around 106 I guess). In the second situation, parity is possible, or even 0.9, but 0.8, hmmmm, and I am also bullish on JPY.
And thank you for your NZD study which inspires me. I think oil is very near its bottom, so it is possible that CAD is near its bottom. For NZD and AUD, I guess NZD will outperform AUD, but they are both affected by the Chinese stock market, which seems not so good.
