Wikipedia says: The US Dollar Index (USDX) is an index or measure of the value of the United States dollar relative to a basket of foreign currencies. It is a weighted geometric mean of the dollar's value compared to the euro (EUR), Japanese yen (JPY), Pound sterling (GBP), Canadian dollar (CAD), Swedish krona (SEK) and Swiss franc (CHF). It was started in March 1973, soon after the dismantling of the Bretton Woods system. At that time, the value of the Dollar Index was 100.000 and has since traded as high as the mid-160s but also into the low 70s. As of October 2008, the USDX was trading in the mid-80s. On March 16, 2008, the index reached 70.698, the lowest since its inception in 1973. The index is updated 24 hours a day, 7 days a week. It is listed on ICE Futures Exchange US (e.g., New York Board of Trade [NYBOT]).
