The US dollar index has enjoyed a nice rally through the better part of the Obama administration and that should be expected during any Democrat US Executive branch's term. An extension of the 1st administration's ( US dollar bullish/commodity ) policies should be expected over the coming few years. It is no surprise then to see the US dollar index has rallied up into a significant battle zone and (at the moment) it has the proverbial wind at its back. Considering the broader commodity market's rather posture of late, a rather sanguine global economic outlook and pending seasonality issues, a continuation of the resent price action (where one should be long from roughly 81.80) wouldn't surprise me in the least. A push through last fall's peak (84.245) will confirm a longer term price pattern which suggests an ultimate target near 90.00 on the index.
