## Survivorship Bias Correction Algorithms

Survivorship bias correction algorithms are mathematical or computational methods used to automatically identify and include delisted assets in backtesting datasets. These algorithms scan historical data for assets that existed in the past but are no longer present in current lists, ensuring they are accounted for in performance calculations.

By dynamically updating the asset universe as the backtest progresses, these algorithms provide a true reflection of how a strategy would have performed over time. In the volatile crypto market, these tools are indispensable for any professional trader or researcher.

They eliminate the manual burden of tracking failed assets and provide a statistically sound basis for evaluating the real-world viability of trading strategies, preventing the over-optimistic results caused by survivor-only data.
