I’m not sure it has to have an edge over everyone else but it has to have a statistically proven probability of making money in the long run.
My strategy is a simple reversal strategy that only has a few criteria. It has a win rate of 40% but the wins are larger than the losses. Year after year it makes a profit. I consider part of my edge as having the discipline to take the next trade after having a series of losses. You know following my plan.
I’d hazard a guess that more traders fail from lack of discipline than from not having a defined edge.
Probably true.
