Options pricing looks intimidating until you separate it into the four Greeks that actually drive it. Each one answers a different question about how the option's price will react as conditions change.
Delta and Gamma
Delta tells you how much an option's price moves for every ₹1 move in the underlying. Gamma tells you how fast that Delta itself is changing — important near expiry, when Delta can shift rapidly for at-the-money options.
Theta and Vega
Theta measures time decay: how much value an option loses each day, all else equal. It's the reason option buyers are fighting a clock and option sellers often have time working in their favour. Vega measures sensitivity to implied volatility — a spike in expected volatility (ahead of earnings or an RBI policy announcement, for example) can move an option's price even if the underlying hasn't moved at all.
Our Options Buying & Selling course builds live option-chain exercises around each Greek, so the concepts move from formulas to something you can actually read on a broker's terminal.
