I worked as a trader in London's financial markets for nearly 20 years and we relied in 2 major news services : Reuters and Bloomberg ... Bloomberg has an analysis on:
http://www.bloomberg.com/apps/news?pid=20601087&sid=aG0KZrYJ3eAk&refer=home This one focuses more on the Euro than the dollar , but does cover the cross exchange .
I would definitely say that the only reason that the dollar is strong right now is that investors have no other option ( the devil you know ! ) . Currency and equity markets are in turmoil and the root is the US economy ( which traditionally leads all financial markets ) . The present administration in USA has , seemingly , mismanaged the economy and Wall Street on a monumental scale and it's going to take the new administration years to unravel it .
When I saw Lehman Bros go under it was complete shock ... They were so incredibly respected in all the financial centres .
It's difficult to call where the dollar goes but whilst this remains a global economic disaster ( and that's what it is ! ) investors will pile into the dollar as the best of the worst .
When I was in London we traders often questioned why the dollar was given such status , as the Euro and the Pound were more often stronger , but you can't get away with the fact that the USA economy is the most important in the world .
