I am curious if anyone finds this magazine and the associated websites (Traders.com advantage and working money.com) useful?
In general yes it is useful. You can find information about services (brokers), software, regulations (very general), literature, technical analysis and general market overview. TA applicability is questionable but reading it gives you overview of what others are thinking about the markets and what is their approach to trading and trade management. There is also some expert opinion, interviews and QA covering various topics. I would recommend it as a general overview of current trading/markets environment.
