Yes. I am sure about that by the amount of "edge" related questions around here nobody has one or has any idea how to get one. My "edge" is knowing statistically where price is going, and my method of entry and exiting of trades without stop losses.
I control what I do. I choose when to get in and when to get out. Think of how well I could do at the blackjack table if I could wait to place my bet after seeing the dealers cards or reduce my bet if I didn't like my cards or increase my bet after seeing both mine and the dealers cards. Would you say I had an edge. How about your own chart reading ability? Would you consider that an edge?
There's a lot of wisdom everywhere you look....try to observe it, glean it, have The Shine like that little boy in The Shining...and you'll be wise and successful as a trader. Not everything has to be literally spelled out and laid out for you in life
You can have an edge as in ability... But there's no magical formula that's going to make you profitable long-term. Renaissance hedge fund developed a system that gave them an edge...but apparently it had more to do with execution and detecting anomalies than a rigid rule based system.
