Trading System Biases

Algorithm

Trading system biases frequently originate within the algorithmic construction itself, manifesting as unintended consequences of coded logic. Parameter optimization, while aiming for profitability, can lead to overfitting to historical data, diminishing future performance in evolving market conditions. The inherent limitations of backtesting, particularly in accurately simulating real-world execution costs and market impact, contribute to a skewed assessment of algorithmic efficacy, and subsequently, biased trading decisions.
