This is a daily chart of the USD Index. It is used to get an idea of the strength/weakness of the USD against a basket of currencies.

A move off of the highs in the last couple of weeks seems to be over with another strong move up today. This may be the sign we are looking for as a hint that the USD will continue to rally. I have been avoiding trading the USD for a few weeks now based on the uncertainty of the US financial markets, but this chart shows me that it may be time to once again look for trading opportunities to take advantage of a stronger USD.
