Actually both Mark Fisher and Maverick emphasize reading a lot of news and other articles all the time. Not just the short-term stuff like FOMC and API etc but also news no one else pays attention to (Fisher liked the site debka.com for its coverage of Middle East stuff, Mav talked about how he used to pick the stocks no one else was looking at just before they made a huge move by looking at the news), and also the bigger term macro picture (in Fisher's seminar the SARS thing was going on and he asked participants to think about how that would affect oil and the economy.
So ACD really isn't a TA system just used like that -- it tracks volatility levels very well in relation to news which is where the whole good news, bad action thing comes in too. I noticed for example that even on short term events, the short-term movement often stops at the levels ACD gives me. Longer-term it might or might not follow the same direction.
