| Win Rate | EV per trade |
|---|---|
| 40% | +20.0¢ / $1 risk |
| 45% | +35.0¢ / $1 risk |
| 50% | +50.0¢ / $1 risk |

EV = (Win Rate × R:R) − (1 − Win Rate). Positive EV means the strategy is profitable long-term.
Break-even win rate = 1 ÷ (1 + R:R). A 1:2 ratio requires winning only 33% of trades to break even. Professional traders target at least 1:2.
