Options Greeks Mastery
Delta • Gamma • Theta • Vega • Rho
Greeks are the hidden engine behind options premium movement. If you understand Greeks, you stop trading options like a gambler and start trading them like a professional. This module teaches every Greek practically with simulations and expiry week behavior.
Module Outcomes
Module 22 Lesson Map
Greeks define how premium reacts to price, time, volatility, and interest rates. Greeks are not optional — they are mandatory.
Greeks Premium Simulator (Delta + Gamma Effect)
Adjust spot price movement and see how premium changes with delta and gamma acceleration.
Inputs
📌 Gamma = speed of delta change.
Theta Decay Simulator (Time Value Loss)
Theta decay accelerates near expiry. This simulator shows premium decay across days.

IV (Vega) Impact Simulator
Vega measures how much premium changes when volatility changes.
Implied Volatility (IV)

Premium Change
Lesson 1: Delta Explained with Examples
Delta tells how much option premium changes for every 1 point move in the underlying.
Delta Meaning
- Delta ranges from 0.00 to 1.00 for calls
- Delta ranges from -0.00 to -1.00 for puts
- ATM options usually have delta around 0.50
Lesson 2: Gamma and Speed of Delta
Gamma tells how quickly delta changes when price moves.
Gamma Insight
- Gamma is highest near ATM
- Gamma increases sharply in expiry week
- High gamma = fast premium swings
Lesson 3: Theta Decay Explained Practically
Theta is the daily premium loss due to time passing.
Theta Reality
- Option buyers lose money if price stays sideways
- Theta decay accelerates near expiry
- OTM options decay fastest
Lesson 4: Vega & Volatility Impact
Vega tells how much premium changes if IV changes.
Vega Rules
- High IV = expensive options
- Low IV = cheap options
- IV crash after event causes premium crush
Lesson 5: Rho Basics
Rho measures premium sensitivity to interest rate changes.
Rho is Minor for Intraday
- Rho matters more for long-term options
- Intraday impact is usually negligible
- Still important for understanding pricing models
Lesson 6: Greeks in Expiry Week
Expiry week is the battlefield of theta + gamma.
Expiry Week Behavior
- Theta decay becomes extremely fast
- Gamma becomes extremely sensitive near ATM
- Premium becomes unstable and fast-moving
Lesson 7: Greeks for Buyers vs Sellers
Buyers fight theta. Sellers benefit from theta.
Buyer vs Seller Logic
- Buyers need price movement + momentum
- Sellers want sideways market + time decay
- High IV benefits sellers more than buyers
Lesson 8: Greeks Based Strategy Building
Greeks are the foundation of professional strategy design.
Strategy Framework
- Momentum strategy → focus Delta + Gamma
- Range strategy → focus Theta selling
- Volatility strategy → focus Vega & IV changes
- Expiry strategies → focus Theta + Gamma balance
