I agree, and I vaguely remember reading that interview as well. However, as I recall, he didn't disclose, let alone publish, his method either in its entirety or in part. So the point is somewhat moot insofar as that interviewee is concerned.Quote from Brandonf:
I cant remember who it was in Market Wizards that said he could publish his entire method on the front page of the NY Times and Wall Street Journal and it would not effect the profitability of it because people would not have the discipline to follow it. So true.
