Yes. Even Ophir has said, you just keep doing the same thing as long as it works. Then, eventually the day will come, either from moving into a bear market, or, just by having the strategy get too popular, even if we remain in the bull market, where it long longer works.
He said, your last trade will always be a losing trade, when you ultimately discover that a particular strategy is finished.
As long as you remain in a very small minority, it gives you an edge, even though it may not guaranty success.
Those were my thoughts.
