What changes after costs
The raw price ratio compares the target distance with the stop distance. The net ratio subtracts fees and a slippage allowance from a winning trade and adds them to a losing trade. That is the ratio used for breakeven win rate and expectancy.
Expectancy formula
Expected value per trade = win rate × net target gain − loss rate × loss at stop. It is an average across a comparable sample, not a prediction for the next trade.
