My money is on Mr Volatile,
who I think made some important points in a very sensible manner - you have my vote anyway!
Profits for Updata - well, there's pros and cons.... if you understand the books etc and put the work in you can figure out what most people will want in a program without being any good at trading yourself. I have no idea if J Du P is making a packet, or for that matter anyone else in the market technicians society, that doesn't stop him designing an excellent tool for trading.
I would argue that this also doesn't qualify anyone to teach others how to trade - attending a seminar on 'how to use Updata' or 'advanced use of Updata' therefore is fine, a seminar called 'how to trade with Updata' (or any other program for that matter, my own included) should e able to point to a real trading record showing that the methods being taught actually work...for that I'd want to see a record of several years actual trades made, not a spreadsheet listing optimised backtests that if only I'd thought of them in 2000 would have made me rich.
I think VN was spot on frankly, I don't think Updata are any worse than anyone else, and I suspect they are better than many, many out there, but personally I'd invest my money in personal coaching from someone who was willing to provide some proof they were good at it. I can readily agree that if you are not totally fluent with Updata TA then it might well be worthwhile attending to improve your own ability to make use of it.
I think VN offered an anti, but well reasoned argument - I also think he deserved a well reasoned argument against,
