Key performance indicators that measure the reliability, consistency and long‑term resilience of algorithmic trading strategies across market regimes.
Stability and robustness metrics evaluate how consistently a strategy performs across different market conditions, assets and time periods. They help determine whether a system is genuinely reliable or simply overfitted to historical data.
A stable strategy produces a smooth equity curve with minimal volatility and controlled drawdowns.
Measures risk‑adjusted returns. Higher Sharpe indicates more stable performance relative to volatility.
Similar to Sharpe but penalizes only downside volatility — a more realistic measure for trading systems.
A robust strategy maintains a consistent profit factor across multiple periods and assets.
The most important robustness test — how well the strategy performs on unseen data.
Measures how closely out‑of‑sample performance matches optimized in‑sample results.
Evaluates how performance changes under randomized trade sequences and stress scenarios.
Robust strategies perform well across broad parameter ranges, not just narrow peaks.
A stable strategy should perform consistently across different assets and market regimes:
Drawdowns reveal how a strategy behaves under stress. Key metrics include:
A robust equity curve shows:
