FAQ
What is trading expectancy?
Expectancy is the average amount you can expect to win (or lose) per trade over many trades: Expectancy = (Win% × Average win) − (Loss% × Average loss). Positive = a profitable system over time; negative = it bleeds, no matter how good any single trade feels.
What is expectancy in R?
Expressed in R (multiples of risk), expectancy = Win% × (avg win in R) − Loss%. An expectancy of +0.3R means you net about a third of your risk per trade on average — multiply by trades and by risk-per-trade to project P&L.
