$USD (US Dollar Index)
UUP (US Dollar Index Bullish Fund ETF
$XEU (Euro Index)
Also I remember a few days ago Peter Schiff thought the Dollar Index was putting in a head and shoulders top and the Euro a head and shoulders bottom (Schiff Report 6/25/2010). He said the bear market rally in the Dollar was over. Schiff also wants to know who will front the bill for a Freddie and Fannie bailout.
