A structured summary of the Walk-Forward Analysis validation, engine timelines, and risk framework powering the ZenWave portfolio.
Walk-Forward Analysis (WFA) is a sequential validation method that optimises on in-sample data, then tests on unseen out-of-sample segments. Each "slice" produces performance on data the optimiser has never seen.
For ZenWave, WFA is not optional — it is the only accepted validation method. All published equity curves are stitched out-of-sample results.
Validation includes:
This creates institutional-grade validation rigor and minimizes the chance of overfitting or false robustness.
Four rolling slices spanning 2014 to 2025. Each row below shows the IS optimisation window and OOS validation period.
| Slice | IS Period | OOS Period | OOS Result |
|---|---|---|---|
| A1 | 2014–2018 | 2019–2020 | Profitable |
| A2 | 2016–2020 | 2021–2022 | Profitable |
| A3 | 2018–2022 | 2023–2024 | Profitable |
| A4 | 2019–2023 | 2024–2025 | Profitable |
All four slices profitable on unseen data. A4 uses an extended IS window for validation only. Live ZenWave A uses the full-window 2014–2025 parameter set, confirmed stable by all A1–A4 slices.
Five rolling slices spanning July 2018 to 2025.
| Slice | IS Period | OOS Period | OOS Result |
|---|---|---|---|
| B1 | 07/2018–2020 | 2021 | Profitable |
| B2 | 2019–2021 | 2022 | Profitable |
| B3 | 2020–2022 | 2023 | Profitable |
| B4 | 2021–2023 | 2024 | Profitable |
| B5 | 2022–2023 | 2024–2025 | Profitable |
All five slices profitable OOS. B5 selected for production — best IS/OOS alignment, lowest fragility.
The ZenWave portfolio combines validated engines under a shared 0.50% total risk cap per trade cycle, split equally across active engines.

Robustness Conclusion: ZenWave B passes WFA with stable OOS results. B5 is selected for live deployment due to regime alignment and low fragility.
| Engine | Status | Window | Params |
|---|---|---|---|
| ZenWave A | Live | Full-window (2014–2025) | Frozen |
| ZenWave B | Live | B5 slice | Frozen |
As of 31 Dec 2025, ZenWave A and B parameters are frozen. No parameter, risk, or logic changes are permitted outside a formal retirement or replacement decision.
The live deployment matches expectations set by the combined out-of-sample equity curves:
