It is a trade-weighted index. So, it suppose to measure the influence of the trading partners of the U.S. Dollar; so, we get a true picture of the U.S. Dollar. The currency DXY and USDollar available on TV and everywhere else are just average weighted or weighed in other formed, but not trade-weighted. So, not I get a better insight in where the money is flowing in terms of the dollar. I will update it later when I make it better, along with others.
