Judge the System Across a Series of Trades
The source frames trade outcomes in units of risk, R, and illustrates how a minority of winning trades can still produce a positive series when winners are sufficiently larger than losers.
Strategy rule
This is an expectancy concept: win rate cannot be evaluated independently of average win and average loss. The source uses a 3R target repeatedly in its examples, while real strategy parameters should be tested against the strategy's own historical distribution.
FX Nova Bot should log planned R, realized R, slippage and exit reason for every trade. That allows the strategy to be evaluated as a statistical process rather than by isolated wins or losses.
