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

Cool.

It's the latest one. Unknown Market Wizards. The one I had in mind was a trader called John Netto.

I believe there was 1-2 other guys too who would mostly trade around news.

Thanks for the info. Just bought it on Amazon. Hopefully I can glean 1 or 2 good ideas from the book.
