Investors can use the observed movements in a United States currency index (like the USDX) to provide them with an idea of how the United States dollar is varying in value compared to the element currencies in the index. For instance, if the dollar index is surging then so likely is the United States dollar. On the other hand, if the United States dollar index drops, then the dollar is likely to fall in value in the foreign exchange market. 

Many financial media breaks report on fluctuation in the United States dollar index to provide their customers with an idea on how the United States dollar performed in the currency exchange market as an option to note how particular currencies surges or dropped versus the greenback. 

The United States dollar index can also be utilised as an inverse signal of the strength or power of the European Union’s consolidated Euro currency. It is because this currency (EUR) is estimated at an impressive 57.6 per cent in the index. The next big currency in this list of weighting indexes is the Japanese Yen at just 13.6 per cent. 

Another important thing for foreign exchange investors to learn is how market movements in the United States dollar index relate to the fluctuation in the element currencies quoted against the United States dollar.

In contradiction, when an element currency pair is marked as EUR/USD, with the foreign currency placed on the left side of the slash and the United States dollar at the right side of the slash, then the currency pair and the dollar index are inversely proportional. It means that they must move in the two opposite directions, with one falling and the other rising in the value.
