An Options contract is a derivative instrument granting the buyer the right—without obligation—to buy (Call) or sell (Put) a specified quantity of an underlying asset at a predetermined strike price on or before a set expiration date. The buyer pays a premium to secure this right.
- Buyer Benefits: Can exercise the option if profitable; seller must fulfill the obligation.
- No Exercise: If unprofitable, the buyer may let the option expire, releasing the seller from any payout.
Essential Elements of Options Trading
1. Underlying Asset
The asset tied to the contract’s value (e.g., BTC/USD for Bitcoin options).
2. Expiration Date
The deadline to exercise the option.
3. Strike Price
Fixed price to buy/sell the underlying asset upon exercise.
4. Contract Types
- Call Options: Right to buy at the strike price.
- Put Options: Right to sell at the strike price.
5. Exercise Styles
- American: Exercisable anytime before expiry.
- European: Exercisable only at expiry (e.g., OKX options).
6. Option Premium
Cost paid by the buyer to acquire the option.
7. Moneyness
- ITM (In-the-Money): Profitable if exercised.
- ATM (At-the-Money): Strike price ≈ market price.
- OTM (Out-of-the-Money): Unprofitable if exercised.
