Basically. The web is a big place. Just because someone writes something, doesn't mean they know something. And best I could tell from the bio, this guy is trying to make very very specific assumptions about a world he simply hasn't worked in (i.e. the idea that basic human posychological tendancies towards round numbers extends to the people trading large enough amounts to consistently move the market, AND that this doesn't change over time even with the schisms we have had in FX over the past few years, AND that it gives you a genuine edge).
There is an awful lot of this kind of stuff on the web. SOme of it is badly written, and so anyone can spot that it's utter guff. But this guy, to give him his credit, actually makes a few reasonable points, and makes them reasonably eloquently. So it's understandable that people could be a little more likely to be drawn in. But his bio screams chancer to me. I't telling you, with absolute certainty, that the big guys these days do NOT stick their stops at these levels just because they end in a round number. They simply don't. I get paid exorbitant sums of moneyto know this stuff, all day, every day, and react to it.
And even if you knew where all the stops were, that still wouldn't give you an edge. That's not even half the picture. It's just taking a tiny nugget of something and trying to extrapolate a whole worldview from it.
