Look Ahead Bias
Look ahead bias occurs in backtesting when a model uses information that would not have been available at the time the trade was supposedly executed. This can happen if the model uses data from the future to make a decision in the past, such as using the closing price of a day to decide a trade that happened at the opening.
This leads to unrealistically high performance results. It is a common error that invalidates the findings of many quantitative studies.
To prevent this, traders must ensure that their backtesting code strictly respects the chronological flow of information. Only data available at the specific timestamp of the decision should be used.
Eliminating look ahead bias is essential for the integrity of any historical simulation.
