I tried it for a short time and it was going through a substantial drawdown. Many using it were unhappy, and there was a good deal of "unrest" on his private message board.
I have no idea what they have been doing since mid-April. I can say that what I found disturbing was the "cult-like" atmosphere, and the fact that any detractors or people asking valid questions/raising valid concerns were quickly shot down and silenced. That was a big red flag. Also, the fact that he never actually reveals how to calculate his levels - it is truly a proprietary, "black-box" system in that sense. So, another red flag.
Anyway - I think a few other ET'ers were using it, so I am sure they can chime in. IMO - avoid it.
