There really is no right or wrong way to trade -- everyone has their one way or hybrid combination thereof. Every point, counter point argument is a double-edged sword...so no point really in debating. It's not so much about the way of trading, per se -- but more on the Execution of the Trade, and the management of it...that's the skill.
Sounds like what John Grady does from "No B.S. daytrading". The guy only looks at the depth of market when he trades. He has a Youtube channel if you are interested. **- This is not an endorsement of "No B.S. daytrading". I am just mentioning it as a similar style. As lawrence-lugar posted; everyone has their own way to trade. I don't find news, technical indicators or chart patterns particularly useful in my trading either. I know that quite a few use one or more of those tools quite successfully. It wouldn't be much of a market if there was only "one way" to trade.
