An edge is positive expectation.I'm curious as to what actually constitutes an "edge". I have a favorite technical indicator that seemingly works across many time frames, and it is derived from very fundamental math principles. (I came up with the idea in an "aha" moment, tried it out in crude form using stockcharts.com, and gained enough confidence to start researching it. Turns out another guy had the same idea and refined it far beyond anywhere I would have gotten in a reasonable amount of time. I want to make money, not optimize indicators.)
So, let's assume this thing works. Let's assume (for me) it lets me swing trade over periods of a few days to a few weeks with a decent win rate (> 70%) and higher reward than risk. Isn't that an "edge"?
Followup question: how on earth does one perform thousands of points of backtesting on something that might trigger a half dozen trades per year on a given instrument? I've checked dozens of instruments over a few key time frames each to the point where I trust this system, but Holy Moses I am nowhere near "thousands" of backtest points. Am I just fooling myself?
As to your followup question, just test it the same way you would trade it: with multiple instruments. So you're multiplying a low trade count per year by the number of instruments you use. As to thousands of trades, you might downsize to hundreds of trades in your backtesting.
