Definition
The Sharpe ratio measures how much return a strategy generates per unit of volatility. Sharpe = (annualized return - risk-free rate) / annualized stdev. On Hyperliquid copy trading, target Sharpe > 2.0 over a 90-day window. Below 1.0 = mostly noise. whale.ag computes it from on-chain daily-marked equity with the prevailing T-bill as risk-free.
