Am reading Elders Trading for a Living for 3rd time, working my way through the study guide too. I think it is a very good buy, one of the best books for helping you understand all facets of trading, and certainly explains how to use all types of indicators and what they are each useful for. When I feel I have mastered this I intend to get his latest - Come into my Trading Room.The study guides are really good tests of your ability and the answers give decent explanations to help understanding. Good luck in your trading.
