I haven't attended his seminar but have seen a thread about darren winters which was generally positive.My experience with this type of seminar is that you can get all the information cheaper both fundamentally and technical from various books,but the seminars put together various indicators and filters in a ready to use package and networking with others on the course can be interesting and educational.How much is the course by the way?If you look on traders library website you will find many video/cd taped seminars some of which I have purchased and recomend,others I wouldn't.Perhaps you can get some base information if its a system,% accuracy,average win/loss,largest drawdown,minimum needed to trade,length of shortest/longest trade to name a few.If you attend please keep us posted about your opinions.
