Backtester Overview

The Vaanam Backtester allows you to test trading strategies against historical market data to evaluate their potential performance before risking real capital.

What is Backtesting?​

Backtesting is the process of testing a trading strategy using historical data to see how it would have performed in the past. While past performance doesn't guarantee future results, backtesting helps you:

  • Validate ideas — See if your strategy logic actually works
  • Measure risk — Understand drawdowns and volatility
  • Optimize parameters — Test different entry/exit thresholds
  • Build confidence — Know your strategy's historical behavior

Important Disclaimers​

⚠️ Hypothetical Results
Backtesting results are hypothetical and do not represent actual trading. Past performance does not guarantee future results.

Limitations:

  • Survivorship bias — Historical data may not include delisted stocks
  • Look-ahead bias — Ensure your strategy doesn't use future data
  • Overfitting — Strategies optimized for past data may not work going forward
  • Market conditions change — What worked historically may not work in the future
