Option trading involves buying and selling options contracts, which give the right but not the obligation to buy or sell an underlying asset at a pre-agreed price (strike price) before or on a specified date (expiry date).
The buyer pays a premium to the seller for this right.
Options are derivatives, meaning their value is derived from the price of an underlying asset (stock, index, ETF, etc.).
How Does Options Trading Work?
Buyers gain the right to exercise the option anytime before the expiration (American style) or on the expiration date (European style).
Exercising is optional; if conditions aren’t favorable, the buyer can let the option expire, losing only the premium.
Sellers (writers) are obligated to fulfill the contract if the buyer chooses to exercise.

Exercising the option yields profit. • For a call: Spot price > Strike price. • For a put: Spot price < Strike price.
At-The-Money (ATM)
No profit or loss if exercised. • Spot price = Strike price.
