Robbins World Cup trading champion Gianluca Bruni says most traders use the wrong numbers to judge whether their strategy works. “Win rate is vanity. Expectancy is the truth of trading.” A high win rate might look impressive, but it doesn’t prove that a strategy actually makes money. He says traders should focus on two numbers: 1. Expectancy: How much you make, on average, for every dollar risked. 2. Profit factor: Your total profits divided by your total losses. But even a strong profit factor can be misleading. “If you remove your lucky trade, you have a 0.6 profit factor. This means you are not a profitable trader.” One unusually large winner can make a losing strategy look exceptional. His test is simple: remove your best trade and calculate the results again. If the strategy stops making money, your edge may not be as strong as you think. If you removed your best trade, would your strategy still be profitable? Gianluca breaks down the complete statistical process and the advanced risk models behind his trading in the full episode.👇
