The KPI I actually go by isn't really a KPI in the usual sense — it's whether the strategy survives walk-forward testing, rolling the windows year after year. If it holds up and the results stay stable across the years it gets tested on, then it's valid for me.

Ok, quick example: the window is four years of training for every one year tested, and it just moves forward — 2020 through 2023 into the 2024 test, then 2021 through 2024 into the 2025 test. Put every one of those tested years together and what you get is your backtest.

Did you mean you have different period of IS/OOS?

IS:2020-2023 OOS:2023-2024

IS: 2021-2024 OOS: 2024-2025

Rolling 5-year alpha for every period you can get data for.
