I've recently attended a course at their "school" - the 2 day technical analysis course. They somewhat hype what's supposedly working now in their course description, however, it never made it to the course. They say how to use MACD to spot divergences in the course description, and then tell you that the MACD is basically an indicator they don't like. I'm not quite sure I really learned anything new.
The course was a basic introductory course to technical analysis - if you're thinking of attending, I would save the money and just purchase a book from John Murphy - you won't learn any secrets there in Denver. But if you like to ski, I guess its a great destination.
I spoke with others in my class that attended the 4 day course that David Nassar helps teach (I understand he only covers 10-15% of the total class time, correct me if I'm wrong) - not many had great words to say - so I won't repeat them here. Let's just say they felt it wasn't worth the money - with or without the 125% reimbursement from Terranova. Since I didn't attend that class, you'd be better to ask others who did.
As for me, I attended after posting notes here in elitetrader with David when he was posting about AMGN back in March. I said at the time I was taking the technical analysis class (which he doesn't teach) but would like to get to learn some of his methods - spend a little time with him. He said sure - just e-mail him when I was coming.
I e-mailed him, told him I was coming, and never heard from him again. When I was there, he was on vacation. Thanks Dave. (if you don't believe me, go search the posts here for the AMGN thread that he started - its all there in black and white) And he told me to critique after I was done - so here it is.
All in all, it wasn't terrible, but I wouldn't recommend it unless you are a total beginner - and then still, I don't think it would be money well spent - even with the 125% reimbursement - it didn't cover staying at a hotel, airfare, car rental, food, etc.
fwiw - I have attended the Webex live trading sessions with David, and he seems to trade well - he is in and out quickly, which is my style, which is why I wanted to sit with him for a bit, but it never materialized.
Also, David did recommend that I NOT take the 4 day course since he didn't feel I would benefit from it (I have been trading for 5-6 years already, and didn't need all the beginner fluff) Thats why he said he would set aside a little time for me.
There's no hard feelings here by me - it just didn't work out - so be it. I've spent money on worse shit than this, and since I'm only 39, I'm sure I will buy some other shit in the future. (heck, the Power Ranger I just bought for my son was a better value than the course

)
Just my 2 cents - I still have my account at Terranova because I think its the best software around, but as for a trading "school", you might want to look elsewhere.
