Quantitative Risk Engine (Rp) • 5-Dimensional Adversarial Stress Audit across 13 Historical Liquidity Fractures
Popperian Falsification Protocol: Built deliberately to break, stress-test, and invalidate quantitative signals prior to live capital deployment.
Exhaustive replay across empirical historical liquidity shocks from 2000 Dot-Com through the 2024 Yen Carry Unwind (anchored to CRSP panels and Corwin-Schultz microstructure execution).
PFI = 0.016 (Hurdle < 0.80), proving that strategy parameters reside in broad, resilient stability basins rather than overfitted peaks.
Simulated execution latency decay with $$t_{1/2} = 48.5\text{ ms}$$; confirms alpha retains profitability even with high queue latency.
Extreme Value Theory tail models assert 12.17% VaR and 17.96% CVaR under catastrophic market dislocations.
Requires a 1.5x simultaneous historical volatility and liquidity shock to breach defined institutional risk limits.
Orders saturate order book depth, forcing spreads wider: s → s × (1 + 3.0 × Q/K). This pushes Microstructure Pressure P upward, forcing non-linear microstructure saturation into rapid decay and collapsing realized alpha mid-execution.
Dynamically dampens allocation by (1 − (P/K)²) × √Depth. When liquidity is tight, size is throttled before order book saturation occurs, cutting market impact friction by over 78%.
Comprehensive out-of-sample stress test results spanning all major liquidity fractures (1987 to 2024)
