Your strategy wins 45% of the time. Your average winner is 2R. Your average loser is 1R. Is that good? Let's calculate it. Winning contribution: 45% × 2R = 0.90R Losing contribution: 55% × 1R = 0.55R Expectancy: +0.35R per trade That does not mean your next trade will make 0.35R. It means that across the historical sample, each trade was worth an average of +0.35R when wins and losses were combined. And that is a much more useful number than simply knowing your win rate. The

You have a 60% win rate. Great. Your average winner is $40. Y our average loser is $50. Still great? Maybe. This is where trade expectancy comes in. Expectancy combines your win rate, average winner, and average loser into one number that estimates what your historical results have produced per trade, on average. It's one of the best ways to answer the question: does this method actually have a mathematical edge? Not "did I win today?" Not "did I have a great week?" Not even
