First of all I am really looking for responses from the following ET members listed below. My reasons for selecting like this is after reading many of the posts generated by these posters my perceptions are that these traders are successful on a day trading timeframe. Should you consider to be at these posters levels then feel free to contribute. What I am looking for assistance with is what exactly defines an edge and moreover a discretionary edge or if there is even such a thing. The list is as follows and not in rank order: Blotto Experiencedjoe Ghost_of_blotto Garachen Rearden Metal Rallymode Acrary - However Acrary's edges seem to be more of a quant style derived from the use of software, however please feel to contribute of relevant. It seems that trading forums become so diluted with the gibberish that gets construed as gospel by "non traders". We see literally hundreds upon thousands of systems that are created around things that I consider to be not even market related. Unfortunately certain types of TA fall into this category which will probably annoy a lot of people by me saying so. For me an edge is something that has to be constructed around exploitation of the sometimes repeatable patterns of traders and unfortunately most TA techniques fall into this category.
