What is walk-forward analysis in forex algorithm testing?

Walk-forward analysis divides historical data into segments. A strategy is optimized on one segment, then tested on the next, repeating the process. Institutions use this to mimic evolving markets. Retail traders can implement walk-forward testing via advanced software. Benefits: avoids curve-fitting and reveals adaptability. Risks: complexity and time requirements. Walk-forward analysis reflects reality—markets change, so strategies must evolve. It’s a disciplined way to separate robust systems from fragile ones.
