Quote from Crispy:
His mkt wizards interview stated much lower %s. I think it was "my best guy gets it right 53% of the time".
53% of the time, the best traders in the world. Think about that. This game is about base hits, not home runs...
Whatever the number, I agree that it isn't anywhere near 100% and that really a significant number of your trades are just breakeven, when you add together the winners and losers and the largest percentage of your gains will come from the few big winners.
I've asked a couple of times for examples among well-known traders of it being otherwise and have gotten crickets.
In baseball, even the biggest sluggers hit more singles than home runs and they're taking home run swings at every pitch they think they can hit a home run on. Some things just aren't in the realm of human capability, even if they are within the realm of human imagination.
