What is expectancy in forex and how can traders calculate it?

Expectancy measures the average amount a trader can expect to win (or lose) per trade. Formula: (Win rate × Average Win) − (Loss rate × Average Loss). Institutions rely on expectancy models to evaluate systems objectively. Retail traders often confuse high win rates with profitability, ignoring expectancy. Benefits: clarity about long-term viability of a strategy. Risks: overestimating expectancy based on small sample sizes. By tracking expectancy monthly, traders can evaluate whether they truly have an edge. Expectancy transforms forex from emotional guessing into a probability-based business model.
