VetoTrader is a calibrated measurement instrument for market structural conditions.
Each output is a Reading — a structured record of what was measured, when, and against what reference.
VetoTrader observes how markets behave structurally and classifies the observation into a small number of ordered states.
Readings are not predictions. They are not signals. They are not recommendations.
Structural volatility state of the US equity market.
ENV_001 uses SPY as a measurement proxy and classifies each trading session relative to a fixed 2006–2025 historical reference distribution.
Frozen definition. Fixed schema. Reproducible output.
VetoTrader is designed to admit additional instruments through the same governed lifecycle.
A Historical Episode Report is a structured record of a single contiguous state period.
Each report contains episode identity, per-session instrument output, persistence information, distribution summaries, and provenance metadata. No interpretation is added.
One example report, ep047, is currently available on request.
VetoTrader maintains the distinction deliberately. The system measures. Interpretation and decision sit outside the system boundary.
