How it works
Ratio and win rate go together
The risk/reward ratio compares what you can gain with what you can lose. At 1:1 you need to win more than 50%; at 1:2, more than 33.3%; at 1:3, more than 25%.
Expectancy combines both: expectancy = win rate × ratio − (1 − win rate). Expressed in R (multiples of your risk), it tells you how much you win or lose on average per unit risked.
FormulaRatio = |Target − Entry| ÷ |Entry − Stop| · Break-even win rate = 1 ÷ (1 + Ratio)
