I'm about to get the Iphone. Other than Bloomberg - what are some other relevant software apps. for traders?
This is not an app, but a webpage: http://www.cmsfx.com/ If you open it up via iphone, it loads the mobile version of fx chart. Its pretty cool. My broker IB also has a mobile version of their site (very light though) that I access via iPhone.
I forgot to say, you can create buttons for your web bookmarks on your iPhone's main screen, so it looks like an app.
