Option Greeks Terminal

Real-time Delta, Gamma, Theta, Vega, and Rho analysis across all NIFTY and Bank NIFTY strikes with live IV and visual heatmaps.

Primary Use CaseUnderstand exact risk profile of open options positions and size trades based on quantified Greeks exposure.

Overview

The STOCKAN Option Greeks Terminal gives you institutional-grade visibility into the risk dimensions of every NIFTY, Bank NIFTY, and SENSEX option contract. Instead of guessing how your premium will move, you see the exact mathematical sensitivity in real-time.

Key Metrics Displayed

Delta (Δ)

Shows how much your option premium changes for every ₹1 move in the underlying index. A Delta of 0.52 on a NIFTY 24900 CE means the premium increases by ₹0.52 for every ₹1 NIFTY rises.

Practical uses:

  • Calculate effective notional exposure of your options portfolio
  • Build Delta-neutral spreads
  • Understand probability of expiring ITM (Delta ≈ probability ITM)

Gamma (Γ)

The rate of change of Delta. High Gamma near expiry means your Delta changes rapidly with index movement — a major source of risk and opportunity in expiry-week trading.

Watch Gamma carefully:

  • Gamma peaks for ATM options close to expiry
  • Long Gamma positions profit from large moves
  • Short Gamma positions (common for premium sellers) face explosive risk during fast markets

Theta (Θ)

Daily time decay in rupee terms. The terminal shows you exactly how much premium your position loses per calendar day.

Features:

  • View Theta as ₹ per lot per day
  • See how Theta accelerates in the final 7 days
  • Weekend Theta visualization (3-day decay in 2 days)

Vega (V)

Sensitivity to a 1-percentage-point change in Implied Volatility. Critical for understanding how India VIX moves affect your position value.

Use cases:

  • Identify Vega-expensive options before major events
  • Construct Vega-neutral positions
  • Plan for post-event IV crush

Rho (ρ)

Sensitivity to interest rate changes. Relevant for long-dated options or during RBI policy meetings.

How to Use the Greeks Terminal

  1. Select the Underlying: NIFTY 50, Bank NIFTY, or SENSEX
  2. Choose Expiry: Weekly (current/next) or Monthly

  5. Portfolio Mode: Enter your positions to see aggregate portfolio Greeks

Greeks Interpretation Quick Reference

Greek Positive = Negative =
Delta Long calls / Short puts Long puts / Short calls
Gamma Long options Short options
Theta Not possible All long options
Vega Long options (IV exposure) Short options

Risk Management Applications

Position Sizing Using Delta

Never risk more than 0.5% of portfolio on a single Delta unit. If your total portfolio Delta is 50 and NIFTY moves 100 points against you, that's ₹5,000 per lot of impact.

Gamma Awareness on Expiry

Reduce position sizes when Gamma > 0.01 per point (typical for near-expiry ATM strikes). High Gamma = high sensitivity = need for smaller position sizes or active hedging.

Theta Budget

Know your daily bleed before entering any long options position. If your portfolio loses ₹2,000/day in Theta, you need the market to move in your favor by that much just to break even.

Data Sources

Greeks are calculated using the Black-Scholes-Merton model with live NSE underlying prices and IV inputs from the option chain. Data refreshes every 30 seconds during market hours.
