What is Trading Expectancy?

Expectancy is the average dollar amount you expect to make (or lose) per trade over a large sample. It's the single best measure of whether your strategy has a real edge — and it accounts for both your win rate AND your average win/loss size.

Expectancy = (Win Rate × Avg Win) − (Loss Rate × Avg Loss)

How to interpret your expectancy

Positive expectancy — Your strategy has a mathematical edge. Execute consistently and you'll be profitable over a large sample.

Negative expectancy — Even with great execution, you'll lose money long-term. The strategy needs work — either improve win rate, improve average winner, or reduce average loser.

The Profit Factor

Profit Factor = Total Wins ÷ Total Losses

Profit Factor above 1.5 is considered acceptable. Above 2.0 is strong. The higher your profit factor, the more durable your edge is across different market conditions.
