The Tape

what the models knew, when

— — reconstructed from archived model runs (deterministic values + a lead-dependent Gaussian error model, labeled, never on the tape) · — live prices from the running consensus engine.

Verdict

This prop went golden 3.8 days before settlement; traded as low as 3¢ and still hit; crossed 70¢ in both directions — a genuine whiplash.
