I have a semi-automated system. i.e. My system processes both news and quotes in realtime, and when my algorithm detects a possible buy or short, it pops up a screen with the relevant news and other info displayed. The amount and price fields are already filled in so all I have to do is press the Enter key. Basically I try to make the trade decision in under 2 seconds. Not fully automated, but close. Too much can go wrong with fully automated systems.
BTW, what is the name of Schwager's book that mentions news trading? Thanks
