No, I actually lost money using their techniques. As I wrote above, more often than not the price often sailed thru` the support/resistance levels predicted by the Gann lines/angles. On occasion they "worked", but in my view by no more than the laws of probability would suggest. As with any form of technical analysis, the "true believers" in any particular method will cherry pick points on charts showing when it has worked to perfection, whilst conveniently glossing over those times when it hasn`t.
The company were always friendly and supportive, in the basics of their system, although if you wanted training beyond the basics (e.g. group seminars or one-to-one training) I seem to remember there were additional charges.
As for advice, within the standard package they provided a (nightly) commentary on potential trades which they had selected & on any stocks which subscribers had submitted for analysis. However, in my experience, there seemed to be as many losers as gainers in their selections. As such I mainly referred to the commentary as an educational aid, and used their software to make my own mind up about trades.
No, I don`t know anyone else using their system.
I`m trading now using my own blend of (modern)technical analysis, which basically involves entering at pullbacks/rallies from established uptrends/downtrends. This doesn`t include any Gann based methodology! What I`ve learnt over the years, from giving large amounts of my cash away to a variety of firms like Gann Management, is that you have to develop your own way of trading which suits your individual personality & risk tolerance. Psychology is often said to be by far the most important factor in any successful trading methodology. Expecting other people`s trading & risk management methods to suit you & make you an easy fortune is largely a fool`s game.
