Backtesting en NinjaTrader 8

Guía completa sobre backtesting en NinjaTrader 8. Profit factor, drawdown máximo, win rate y cómo evitar overfitting en estrategias algorítmicas.

Backtesting validates trading strategies against historical data. This guide covers profit factor, maximum drawdown, Sharpe ratio, win rate, and how to avoid common pitfalls like overfitting and survivorship bias on NinjaTrader 8.

Key Performance Metrics

Understanding backtest metrics is essential for evaluating any algorithmic strategy. Profit factor is the ratio of gross profit to gross loss, with values above 1.5 considered good. Maximum drawdown measures the largest peak-to-trough decline in equity, reflecting the worst-case scenario for account balance. Win rate is the percentage of trades that were profitable, and Sharpe ratio measures risk-adjusted returns by comparing average return to return volatility.

Avoiding Overfitting

Overfitting occurs when a strategy is optimized too closely to historical data and fails to perform on new, unseen data. Signs of overfitting include an unusually high number of parameters, extremely high backtest returns that seem too good to be true, and significant performance degradation on out-of-sample data. The best defense is to use walk-forward analysis, limit the number of free parameters, and test on multiple instruments and time periods.
