OSIP

// Overview

OSIP (Options Scenario & Impact Platform) is a portfolio simulation engine for retail and professional options traders. Users define a portfolio of positions, set market assumptions, and run thousands of Monte Carlo paths to stress-test outcomes across volatility regimes.

The backend runs on AWS Lambda with S3 for state persistence, keeping compute costs near zero while supporting on-demand simulation bursts. The React frontend provides real-time P&L distributions, Greeks aggregation, and scenario comparison across runs.

Built out of a real need: existing retail tools lacked the ability to simulate complex multi-leg structures with correlated underlyings. OSIP fills that gap with an architecture that scales without the cost of always-on infrastructure.
