LAB 03 / MARKET MICROSTRUCTURE / DETERMINISTIC TAPE

Trade the
failure regime.

Change adverse selection, quote staleness, and inventory control. The live tape explains mechanism; committed 20,000-step, 12-seed results remain the quantitative authority.

SIMULATION CONTRACT

The browser tape is explanatory. The benchmark is evidentiary.

This page uses a seeded, lightweight order-flow model so every shared URL replays the same regime. It does not claim to reproduce the repository’s full Python experiment in real time. P&L, edge, inventory dispersion, and AAD accuracy are taken from locally reproduced repository benchmarks; the changing live P&L is deliberately labeled illustrative.
