He hasn't embarrassed himself at all. He's made a point and it's a valid one. You don't have to agree with it, but you'd do well to at least take note of it. I don't think he's saying that 1-minute charts are completely irrelevant, but saying what GammerJammer said which is that the smaller timeframe you're on, the smaller the moves TYPICALLY are so that your gains are eaten up by costs, plus if you're going to use 1%/2% risk per trade on stops of 5 pips etc, then there's nothing stopping a central bank placing a limit order 1000 pips above where price is and your account getting blown and more. It might never happen to you, but you have to be open to the possibility. If you can withstand that kind of hit, and you have money set aside to start again, and you can make good money off the 1-minute then fine. But for most people, it's not going to be a good idea, and I say this as someone who DOES use 1-minute in their trading, and finds it very useful.
