Robust validation — overfitting, walk-forward & stress testing

Clean data and realistic costs are still not enough. Overfitting remains the largest reason attractive backtests fail live. Walk-forward analysis, stress tests, and practical decision rules so you know when an edge is real enough to promote.

In this module

  1. The biggest remaining lie
  2. In-sample vs out-of-sample — the core distinction
  3. Walk-forward analysis — the practical gold standard
  4. Additional stress tests
  5. Practical decision rules
  6. Robust validation checklist
  7. Where FreqEdge and the Quant Agent help
  8. Key takeaways
Practice

Run a proper held-out validation on one edge

Open Edge Lab and pick an edge that already has a backtest. Use Quant Agent Validate idea (or the equivalent held-out option). Compare the in-sample metrics to the held-out result. Note the decay and decide whether the edge should stay in VALIDATED, move toward PROVEN, or be killed.
