The Only Math That Matters in Trading

When it comes to trading, many believe success lies in picking more winners than losers. But in my experience, the real edge comes from understanding one key concept: expectancy. Expectancy is the average amount I can expect to win or lose per trade, factoring in both the probability and size of wins and losses. Even with a win rate below 50%, I can be consistently profitable if my winning trades outweigh my losing ones. That’s why I focus less on being right and more on managing risk and maintaining discipline. In the long run, it’s the math of expectancy—not predictions—that drives success.
