Back-Testing Best Practices

To ensure reliable results from back-testing, traders should adhere to best practices such as accounting for slippage and commissions, avoiding curve fitting, and conducting robustness checks.

Avoiding Common Pitfalls in Back-Testing

• Failing to factor in transaction costs
• Over-optimization leading to curve fitting
• Ignoring market impact and liquidity

Utilizing Historical Data for Effective Back-Testing

Access to quality historical data is paramount for effective back-testing. Data should be as close as possible to the conditions encountered in live trading.

Criteria for Selecting Historical Data Providers

• Data granularity (tick, minute, daily data)
• Data accuracy (corrections for splits, dividends)
• Data completeness (no missing periods)

Human vs. Automated Back-Testing

While automated back-testing offers advantages in speed and accuracy, human oversight can provide context and qualitative assessment that pure automation might miss.
