Hidden Pivot obstacles loom at 77.42 and 77.53, and we should be able to tell how much more buying power is left to drive this rally once we’ve seen DXY interact with them.  The latter number is doubly important, since it lies just above a key peak at 77.47 recorded on October 2.  Looking at a much bigger picture on the weekly chart, the trend could continue to as high as 83.33 without affecting the likelihood that the uptrend since March 2008 has been just a garden-variety bear rally. _______ UPDATE (12:23 a.m.):  DXY has blown the roof off resistance in night trading, taking out all three resistance points  noted above.  Since there has yet to be a pullback, the full power of the impulse leg begun from 74.27  on December 1 has yet to be revealed.
