## Walk-Forward Testing

Walk-forward testing is a rigorous validation method used to evaluate the performance of trading strategies by simulating real-world application over time. Instead of testing on one large static dataset, the data is divided into sequential segments, where the model is trained on one window and tested on the immediate next segment.

This process repeats, effectively sliding the window forward across the entire historical timeline to see how the model adapts to changing market conditions. In the crypto domain, this is vital because market dynamics, such as institutional flow or protocol upgrades, change rapidly.

By continuously re-training and testing, traders can observe if the model maintains its edge or if its performance decays as it encounters new data. It provides a more realistic assessment of how a strategy will behave when it is actually deployed in a live market.
