Strategy Complexity: Many advanced statistical methods already available and well-tested. What are key reasons for backtesting an algorithmic strategy?


Look-Ahead Bias Look-ahead bias is introduced into a backtesting system when future data is accidentally included at a point in the simulation where that data would not have actually been available. Modelling - Backtesting allows us to (safely!) test new models of certain market phenomena, such as transaction costs, order routing, latency, liquidity or other market microstructure issues.
