The comment in the Adaptive Analysis thread that 97% of traders failed really astounded me. Is this comment fact, can anyone show statistical evidence from a reliable source that this the case. Or is the comment used similar to the comments used by real estate agents, used car salesmen and other snake oilers. Am I one of the 97% or one of the 3%? I wonder how I determine success or failure. Is there cut off point in return from trading capital that determines success or failure. Is a 10% return failure or is 15%? Certainly losing your capital is failure. I would always like to improve my trading but how do I determine if I am successful? I have my trading plan and over the last three years have achieved my goals and have improved my performance (return) each year. So is someone failing if they do not achieve someone elses standard or use their method.
