Currency indices measure direct changes in the value of a currency against a basket of other currencies. This differs from a currency pair in that there must be more than one other currency that the main currency is being measured against.

Globally recognised as a benchmark for the value of the US dollar, the USDX is the most traded currency index and can be traded with us as a CFD with leverage of up to 5:1. USDX is most heavily weighted toward the major currencies such as the Euro, Yen and Pound - with 6 currencies in total making up the basket the US Dollar is measured against.
