Sharpe Ratio in Forex
A clear definition of Sharpe Ratio, with practical context for reading markets and making better trading decisions.
Definition
The Sharpe Ratio is a performance measure that compares excess return with the total variability of those returns, using standard deviation as the risk measure.
What It Tries to Answer
The ratio asks how much return was earned for each unit of overall volatility. A higher Sharpe Ratio generally indicates a better historical return-to-volatility relationship, assuming the inputs are comparable.
Limitations
Sharpe treats upside and downside volatility the same and depends on the period, return series, and risk-free-rate assumption. It should not be used as a complete description of risk.
Key Takeaway
Sharpe Ratio compares excess return with total volatility. It is useful for comparison, but only when the strategies and calculation periods are comparable.
