Long Term US Dollar. Good place for possible reversal.

The US Dollar index has been charging upward recently. But you can see from this long term log chart it is at an important down trend line. It is also very close to a 50% retraction on the last major wave down from 2001 to 2009. Plus the RSI is overbought and has a potential bear divergence (this would likely not be true if it keeps charging up). I don't know what will happen but would not be surprised to see a reversal here.
