What is Backtesting and Why it Matters

Backtesting involves using historical data to simulate how a strategy would have performed as if real trades were placed in the past according to the rules.

Adjusting the backtest date range allows you to:

  • Gauge performance across bull, bear, range-bound markets
  • Verify strategy worked in different decades with changing conditions
  • Check for anomalies only during certain time periods
  • Optimize strategy rules based on periods with certain results
  • Confirm strategy has an edge over long timeframes

Robust strategies prove effective across various market eras.
