Portfolio Stats – Sharpe & Sortino Ratio Calculator

Choose this endpoint when you need both Sharpe and Sortino ratios computed together from a raw price or return series without requiring any external data lookup — you supply everything. It is ideal for backtesting, strategy evaluation, or portfolio analytics pipelines where data is already in hand and a quick, cheap ($0.02) risk-adjusted performance computation is needed. Prefer it over broader equity-curve summary endpoints when you specifically need Sharpe/Sortino focus with customizable risk-free rate and annualization period.

• Missing or malformed price/return series — returns error if neither prices nor returns are supplied
• Both prices and returns supplied simultaneously — endpoint expects one or the other, not both
• Fewer than 2 data points — insufficient data for meaningful ratio computation
• Invalid JSON format for price/return array — malformed input causes parse errors
• Non-numeric values in the series — will fail or return degraded results
• Conflicting unit parameter with data format — mismatched unit enum causes incorrect computation
