Actually an excercise I tried for a couple weeks: Just watch the screen all day and after the market closes go find the news that moved whatever you're watching. You'll know something is happening but does it (the particular news) matter. There's a whole bunch of questions you can ask yourself.
I do not trade news, but have a screen that is displaying IRC news feeds from: OtherNet: #newsroom FinancialChat #Headlines Download Xchat, it is free. Turn off the join/leave, and other annoying messages and it is not bad. Good luck,
