# Bot's Performance Stats StockHero offers traders two of the most common metrics used to track financial performance for an investment: the Sharpe Ratio and the Max Drawdown. In principle, a Sharpe Ratio measures the excess returns above the risk-free rate of return. The risk-free rate of return is simply the return on the safest type of investment instrument, such as government bonds and fixed deposits. As each country has its own risk-free type of investment return, StockHero allows the user to set the Risk Free Rate of Return in the Settings page. Go to Settings >> Formula to set your Risk Free Rate. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
