Options Payoff Simulator
🦅 Institutional Derivatives Terminal & Greeks Engine
Full Black-Scholes mathematical model profiling real-time Delta, Gamma, Theta, Vega, and T+0 curves.
💡 Terminal User Guide & Interactive Color Matrix
Global Parameter Anchors: Bold text fields on gray or white backgrounds are completely editable. Change these to update Spot, global IV, or Days to Expiry.
Position Leg Attributes: White rows with bold blue text values allow direct entry. Type strikes or premiums manually to construct multi-leg strategies.
Exchange Constraints: Shaded background boxes (like Lot Size) are strictly locked. They shift automatically based on the selected Index contract rules.
Live Option Greeks: Color-coded metrics (Delta, Gamma, Theta, Vega) are real-time Black-Scholes partial calculations and cannot be altered.

Executive Summary: Institutional Option Greeks & Payoff Engine
This production-ready web simulator transitions your platform from basic retail content into an institutional-grade financial analytics terminal. By integrating the Black-Scholes-Merton mathematical model directly into the client-side runtime environment, the engine provides sophisticated derivatives traders with absolute clarity regarding their portfolio risk surfaces.
Core Risk Parameters Computed in Real-Time:
- The Volatility ($IV$) and Time-Decay ($\Theta$) Space: Unlike standard simulators that only plot rigid expiry lines, this engine renders a live T+0 curve using the Black-Scholes partial differential framework. This proves to the user exactly how shifting implied volatility levels and daily time decay affect their positions prior to contract settlement.
- Dynamic Exchange Constraint Sync: The code automatically tracks exchange contract logic for major Indian indices. Toggling between Nifty 50 and Bank Nifty instantly updates the system constraints—recalculating underlying lot sizes (25 vs. 15) and rounding strike steps (50 vs. 100 points) to eliminate manual user setup.
- The Option Greeks Matrix ($\Delta, \Gamma, \Theta, \text{Vega}$): By calculating the normal distribution approximations ($d_1$ and $d_2$) instantly on every user key-stroke, the terminal aggregates individual position greeks to show the user their net portfolio bias:
- Net Delta: Proves if the total strategy is net-bullish, net-bearish, or perfectly delta-neutral.
- Net Gamma: Alerts the trader to the acceleration risk of their delta positions.
- Net Theta: Quantifies the exact daily premium income generated by net-sellers.
- Net Vega: Maps vulnerability to sudden market fear spikes or implied volatility crashes.
User Experience Engineering:
To eliminate any user friction, the layout incorporates a built-in, collapsible Color Matrix Guide at the top. This clearly demarcates user-editable structural fields (styled in Bold Blue Text) from locked exchange-mandated variables and automated mathematical outputs—ensuring an elite, professional terminal experience
