Well yes..... "edge" is a little silly. However, when there is a discussion about knowing what your's is as a trader, the context holds more water. I think it is really important for a trader to understand SPECIFICALLY WHY they think they will win a zero sum game with consistancy. As I formulate my strategy as a discretionary trader, part of that process is defining WHY I expect it to work. That is more complex than it seems. It seem like a cop out to just say..."oh, I expect to win because I know a lot about technical analysis"....... or even to say something like..... "l expect to win because I have spent over 1000 hours watching and analysing markets"(which I have not done yet, but plan to do). That being said, the true edge as a discretionary trader probably closely resembles my second statement. I think that's the catch. No one can teach you to read market context. You have to do your own work.
