Options trading has become a powerful tool for cryptocurrency investors seeking flexibility, risk management, and strategic advantage in volatile markets. OKX offers a robust and transparent options trading platform built on digital assets like Bitcoin (BTC), Ethereum (ETH), and Solana (SOL). This guide provides a comprehensive overview of how OKX options contracts work, their key features, and the benefits they offer to traders.
What Are Options?
An option is a financial derivative that gives the buyer the right—but not the obligation—to buy or sell an underlying asset at a predetermined price on or before a specific date. This unique structure creates asymmetric risk and reward profiles for both buyers and sellers.

There are two primary types of options:
- Call Option: Grants the holder the right to buy the underlying asset at the strike price.
- Put Option: Grants the holder the right to sell the underlying asset at the strike price.
At expiration, if exercising the option is profitable, the buyer can execute it and receive settlement income. If it's unprofitable, the buyer simply lets the option expire, losing only the premium paid. The seller, meanwhile, collects the premium upfront but must fulfill the obligation if the buyer exercises.
Key Elements of an Option
Understanding these core components is essential for effective options trading:
- Underlying Asset: The asset on which the option is based—such as BTC/USD, ETH/USD, or SOL/USD indices.
- Expiration Date: The date when the option contract expires and becomes invalid.
- Strike Price (Exercise Price): The fixed price at which the underlying asset can be bought (call) or sold (put).
Option Type: Classified by exercise style:
- European Option: Can only be exercised at expiration (used by OKX).
- American Option: Can be exercised any time before expiration.
- Bermuda Option: Exercise allowed on specific dates before expiry.
- Premium: The price paid by the buyer to acquire the option rights.
Additionally, options are categorized based on their intrinsic value:
| Option Type | Spot Price vs. Strike Price | Status |
|---|---|---|
| Call | Spot > Strike | In-the-money |
| Call | Spot < Strike | Out-of-the-money |
| Call | Spot = Strike | At-the-money |
| Put | Spot < Strike | In-the-money |
| Put | Spot > Strike | Out-of-the-money |
| Put | Spot = Strike | At-the-money |
Both buyers and sellers can close their positions before expiration through offsetting trades.
Understanding OKX Options Contracts
OKX offers European-style options contracts settled in cryptocurrency. These include BTCUSD, ETHUSD, and SOLUSD options, each with standardized specifications designed for clarity and efficiency.
Each contract represents a fractional amount of the underlying asset:
- BTCUSD: 0.01 BTC per contract
- ETHUSD: 0.1 ETH per contract
- SOLUSD: 1 SOL per contract
Traders can either buy an option to gain directional exposure with limited downside (maximum loss = premium paid), or sell an option to collect premium income while assuming potential obligations at expiry.
Core Contract Specifications
- Contract Types: Call and Put options
- Expiration Frequencies: Daily, weekly, bi-weekly, monthly, quarterly, and beyond
- Underlying Index: BTC/USD, ETH/USD, or SOL/USD index
- Settlement Currency: BTC, ETH, or SOL (digital asset settlement)
- Quoting Currency: Same as settlement currency
- Minimum Price Increment: 0.0005 BTC/ETH/SOL
- Exercise Style: European — automatic exercise for in-the-money options
- Trading Hours: 7x24 market access
- Final Settlement Price: Determined using a time-weighted average from multiple exchanges over the last hour before expiry
- Mark Price: Calculated using the Black pricing model and updated in real-time to reflect fair market value
For example, a contract named BTCUSD-20250328-70000-C refers to a Bitcoin call option:
- Expiring on March 28, 2025
- Strike price: $70,000
- Type: Call (C)
If BTC/USD settles at $75,000 at expiry, the payout would be:
[(75,000 – 70,000) / 75,000] × 0.01 BTC = 0.000667 BTC
No action is required—the system automatically settles all in-the-money contracts.
Why Trade Options on OKX?
OKX’s options framework stands out due to its innovative design focused on transparency, accessibility, and security.
Asymmetric Risk-Reward Profile
Unlike futures contracts where both parties face unlimited risk, options provide distinct advantages:
- Buyers risk only the premium paid but enjoy unlimited profit potential.
- Sellers earn premium income but assume higher risk if the market moves against them.
This makes options ideal for hedging portfolios or speculating with controlled risk.
Flexible Margin System
One of the most attractive features is the asymmetric margin requirement:
- Buyers pay only the premium—no margin needed.
- Sellers must post collateral to cover potential obligations.
This enhances capital efficiency for buyers and ensures sufficient coverage for sellers.
Transparent Pricing & Anti-Manipulation Mechanisms
OKX employs rigorous safeguards against market manipulation:
- Final settlement price uses a volume-weighted average across multiple exchanges.
- A one-hour time-weighted average prevents last-minute price spikes from distorting results.
- The mark price, derived from the Black model, reflects real-time market sentiment and protects against artificial volatility.
These measures ensure fair valuation and reduce forced liquidations due to manipulated prices.
