Cryptocurrency derivatives have become a cornerstone of modern digital asset trading, offering traders advanced tools to hedge risk, speculate on price movements, and optimize portfolio performance. Among these instruments, options stand out for their flexibility and strategic advantages. On platforms like OKX, crypto options provide users with powerful opportunities to engage with Bitcoin and Ethereum markets in a controlled, cost-efficient manner.
This guide dives deep into OKX options, explaining what they are, how they work, and how they compare to other derivative products such as futures. Whether you're new to options trading or looking to refine your strategy, this article will equip you with the knowledge needed to navigate the ecosystem confidently.
What Are Options?
Options are financial derivatives that give the holder the right—but not the obligation—to buy or sell an underlying asset at a predetermined price (known as the strike price) on or before a specified expiration date. This unique feature sets options apart from other instruments: buyers can choose whether to exercise their rights based on market conditions, while sellers (also called writers) assume the obligation if the buyer decides to act.
There are two primary types of options:
- Call Options: Give the holder the right to buy the underlying asset.
- Put Options: Give the holder the right to sell the underlying asset.

Key Concepts in Options Trading
To fully understand how OKX options function, it’s essential to grasp several core terms:
- Underlying Asset: The tradable asset on which the option contract is based. For OKX, this includes Bitcoin (BTC/USD index) and Ethereum (ETH/USD index).
- Expiration Date: The date when the option contract expires. After this point, the option becomes void unless exercised.
- Strike Price: The fixed price at which the holder can buy (for calls) or sell (for puts) the underlying asset.
- Exercise Style: OKX offers European-style options, meaning they can only be exercised at expiration, unlike American-style options, which allow early exercise.
- Option Premium: The price paid by the buyer to the seller for acquiring the option. This is the maximum loss for the buyer and the maximum gain for the seller.
Option Moneyness: In-the-Money, At-the-Money, Out-of-the-Money
The value of an option relative to the current market price of the underlying asset determines its "moneyness":
| Option Type | In-the-Money (ITM) | At-the-Money (ATM) | Out-of-the-Money (OTM) |
|---|---|---|---|
| Call | Spot price > Strike | Spot ≈ Strike | Spot < Strike |
| Put | Spot price < Strike | Spot ≈ Strike | Spot > Strike |
This classification helps traders assess potential profitability and make informed decisions about buying or selling contracts.
OKX Options Contract Specifications
OKX provides a transparent and well-structured framework for trading crypto options. Below are the key specifications that define its offering:
Underlying Assets
Currently, OKX supports options on:
- BTC/USD Index
- ETH/USD Index
These indices reflect real-time market data aggregated from multiple sources, ensuring fair pricing and reduced manipulation risk.
Contract Size
Each contract represents a fractional amount of the underlying cryptocurrency:
- BTC Options: 0.01 BTC per contract
- ETH Options: 0.1 ETH per contract
This design makes options accessible even for traders with smaller capital.
Settlement Token
All options are settled in-kind:
- BTC options → settled in BTC
- ETH options → settled in ETH
This avoids conversion risks and aligns incentives directly with crypto holdings.
Quotation Step
The minimum price movement depends on the premium level:
- Below 0.005 BTC/ETH → step size of 0.0001
- Above 0.005 BTC/ETH → step size of 0.0005
This ensures precision across different volatility environments.
Pricing Model
OKX uses the Black model to calculate real-time fair value, incorporating:
- Market-implied volatility
- Volatility caps and floors
- Time to expiration
This enhances transparency and reduces arbitrage opportunities.
Expiration Schedule
Options are available with various expiration cycles:
- Daily (1–3 days ahead)
- Weekly (1–3 weeks ahead)
- Monthly (1–3 months ahead)
- Quarterly (March, June, September, December cycles)
New contracts are listed daily at 08:30 UTC, with expirations occurring at 08:00 UTC on the respective dates.
Settlement Mechanism
At expiry:
- The settlement price is calculated as the time-weighted average of the index price over the final hour before expiration (with snapshots taken every 200ms).
- ITM (in-the-money) options are automatically exercised.
- All settlements occur via cash settlement in cryptocurrency, ensuring seamless execution without manual intervention.
Trading Hours
OKX options trade 24/7, reflecting the non-stop nature of cryptocurrency markets.
Fees and Limits
Trading fees follow OKX’s standard fee structure. Position and price limits apply to maintain market stability—details are available within the platform’s help center.
Options vs. Futures on OKX: Key Differences
While both options and futures are derivatives used for speculation and hedging, they differ significantly in risk profile, rights, and margin requirements.
| Feature | OKX Options | OKX Futures |
|---|---|---|
| Rights & Obligations | Buyer has right; seller has obligation | Both parties have binding obligations |
| Margin Requirements | Only sellers post margin; buyers pay premium only | Both long and short positions require margin |
| Potential Risk/Reward | Buyer: Limited loss (premium), unlimited gain Seller: Limited gain (premium), unlimited loss | Both sides face unlimited profit and loss potential |
| Exercise Style | European-style (exercise at expiry only) | Immediate settlement upon closing |
This contrast makes options particularly appealing for traders seeking asymmetric risk-reward profiles—where losses are capped but gains remain open-ended.
Frequently Asked Questions (FAQ)
Q: Can I exercise my OKX option before expiration?
A: No. OKX offers European-style options, which can only be exercised at expiration. You cannot manually exercise them earlier.
Q: What happens if my option expires out-of-the-money?
A: If an option expires OTM, it becomes worthless. The buyer loses only the premium paid, and no further action is required.
Q: How is the final settlement price determined?
A: It’s calculated as the time-weighted average of the BTC/USD or ETH/USD index during the last hour before expiration, with data sampled every 200 milliseconds.
Q: Do I need to hold margin if I buy options?
A: No. Buyers only pay the premium. Margin is required only for sellers (writers) of options due to their obligation risk.
Q: Are OKX options physically or cash settled?
A: They are cash-settled in cryptocurrency (BTC or ETH), meaning no actual delivery of spot assets occurs.
Q: Can I trade OKX options on weekends?
A: Yes. Trading is available 24 hours a day, 7 days a week, aligning with global crypto market activity.
