Personally, I'm a nuclear engineer by training. But I cannot make the system a financial engineering exercise of the highest order. I'd have three clients over five years if that was the case. I've chosen by design to take some necessary skills like intermarket correlations and hedge ratio betas and have broken them down into simpler tools and methods that, say, a scalper could do for himself with a little training from me. Still, I have HF analysts, CTA's, and PhD's as clients. If they want to apply what I teach as a baseline gateway into MatLab or S-Plus I say more power to them. But I do very much warn these types of clients that I prefer "quick-and-dirty" versus an academic exercise. The bottom line is the bottom line, and clients have to be able to apply what you're offering them to live trades and they have to be successful at it. It has to translate to the broadest segment of the trader population. I want my clients to make money, because they are going to provide references and referrals for future clients.
I appreciate the points you're making here and I suppose part of my disappointment stems from the fact that the quick and dirty approach with broader appeal just doesn't mesh well with my style of trading. If you'd like some feedback from someone who checked out the service and passed when you're tackling the redesign of the website, feel free to hit me up on PM. I know it's a fine line between sharing enough to get people interested but not giving away any secret sauce.
