+"""S2-08: VRP Honest Test.
+Problemi del test precedente:
+1. IV stimata con moltiplicatore fisso → troppo ottimista
+2. Nessun stress test su crash
+3. Nessun costo di margin
+4. Walk-forward mancante
+
+Fix:
+- IV calcolata come rolling ratio IV/RV da dati DVOL reali (90 giorni)
+  e applicata storicamente con variabilità
+- Stress test esplicito su periodi di crisi
+- Margin requirement: 5% del notional bloccato
+- Walk-forward: retrain IV/RV ratio ogni 30 giorni
+- Fee realistiche: 0.05% maker + 0.05% taker per gamba = 0.2% roundtrip straddle
+- Slippage: 0.1% per esecuzione
