Investigación
Cómo los datos históricos se convierten en evidencia falsable — datasets, backtests, walk-forward, OOS, replay, contrafactuales.
Metodología
Cómo los datos históricos se convierten en evidencia falsable — datasets, backtests, replay, contrafactuales.
Datasets EN
Canonical dataset contracts — fingerprints, quality gates, provenance, and the tick-dataset cache.
Backtesting EN
Deterministic, friction-aware backtests — what is simulated, what is honest about it.
Walk-Forward EN
Purged and embargoed walk-forward validation — why the purge exists and what happens when it was missing.
Puerta OOS EN
The hard OOS gate — floors, rejection semantics, and the evidence that it actually rejects.
Replay EN
Replay and streaming replay — bit-exact parity with the dataset, the anti-leakage guarantee, and how it differs from backtesting.
Contrafactuales EN
The NO_TRADE counterfactual engine — walking the decisions the engine didn't take, with stratified evidence.
Validación
La cadena de puertas — qué significa "validado" y por qué los rechazos se publican.
Reproducibilidad EN
How NSE makes research runs reproducible — fingerprints, frozen captures, deterministic seeds, provenance snapshots.
