Backtesting Insights

Understanding Backtesting

• Backtesting is the process of testing a trading strategy on historical data to assess its viability.
• It allows traders to see how a strategy would have performed without risking real capital.
• Proper backtesting simulates real market conditions, including aspects like slippage and commission fees.

Key Benefits of Backtesting

Limitations and Risks of Backtesting

• Overfitting can occur when a model is too closely tailored to past data, which may not yield similar results in live trading.
• Historical data is limited to specific time frames, possibly excluding recent market changes.
• Backtesting does not incorporate factors like market psychology, news events, or unexpected volatility, which can affect live trading outcomes.

Best Practices in Backtesting

• Use high-quality historical data for more accurate results.
• Test strategies across different market conditions and time frames.
• Combine backtesting with forward testing to validate strategies in live environments.
