Backtest Fidelity, within crypto investing and smart trading, quantifies the accuracy and reliability with which a simulated trading strategy’s historical performance reflects its potential real-world results. It measures the congruence between theoretical outcomes derived from historical data and the actual operational dynamics of a trading system.
Mechanism
Achieving high fidelity requires meticulous data preparation, including cleansing and normalization of historical market data, along with accurate modeling of transaction costs, slippage, latency, and order book dynamics specific to crypto exchanges. The backtesting engine must replicate execution logic, market impact, and funding rate mechanisms with high precision.
Methodology
The methodology for evaluating backtest fidelity involves comparing simulated results against actual trading records, often employing statistical metrics like correlation coefficients, maximum drawdown discrepancies, and profit/loss deviation. Robust analysis identifies potential overfitting, data snooping bias, and look-ahead bias. Techniques such as walk-forward optimization and out-of-sample testing are critical for validating the predictive power of the strategy across different market regimes.
