What you have to understand is there is no "cook book", no easy recipe to trading success. Trading retracements is as old as trading itself. What Halsey offers is a logical and ordered way to enter and target. With some adjustments, it lies at the heart of what we do.....in addition to ideas by Linda Raschke, Al Brooks, Vic Sperandeo, Jeff Cooper, Richard Wycoff, Larry Williams and others. We all stand on the shoulders of giants, including the aforementioned.
You have to formulate your own trade plan based on your understanding of the concepts involved as well as understanding your own personal characteristics. Learning to trade is difficult and takes a lot of time and effort...time and effort that most will not invest.
