Understanding Cryptocurrency Options
Cryptocurrency options are financial derivatives that give traders the right—but not the obligation—to buy or sell a specific digital asset at a predetermined price on or before a set expiration date. This concept mirrors traditional market options but is applied to crypto assets such as Bitcoin (BTC) and Ethereum (ETH).
At its core, an option allows investors to speculate on price movements while capping potential losses. Unlike futures contracts, which require settlement upon expiry, options offer flexibility: you can choose whether or not to exercise your right based on market conditions.
OKX, one of the world’s largest cryptocurrency exchanges, offers a robust options trading platform focused primarily on BTC and ETH. With intuitive tools like “Option Simplified,” even newcomers can start trading confidently.

The Five Key Elements of OKX Options
Every OKX option contract revolves around five essential components:
- Underlying Asset: Currently, OKX supports Bitcoin (BTCUSD) and Ethereum (ETHUSD) options only.
- Strike Price: The fixed price at which the asset can be bought (call) or sold (put).
- Expiration Date: The deadline by which the option must be exercised; after this, the contract becomes void.
- Contract Type: OKX uses European-style options, meaning they can only be exercised at expiration.
- Premium (Option Fee): The cost paid upfront to purchase the option. This fee is non-refundable regardless of whether the option is exercised.
These elements shape every trade decision and influence profitability.
How OKX Option Contracts Are Named
Option symbols may look complex at first glance, but they contain structured information. For example:
BTCUSD-20250627-160000-C
This breaks down into four parts:
- BTCUSD: Underlying asset (Bitcoin vs. USD)
- 20250627: Expiration date (June 27, 2025)
- 160000: Strike price ($160,000)
- C: Call option (P = Put)
So this contract gives the holder the right to buy BTC at $160,000 on June 27, 2025. No action is required if BTC trades below that level—limiting downside risk to just the premium paid.
How to Profit from OKX Options
There are two primary ways to profit from OKX options:
1. Exercising the Option
Suppose BTC is trading at $100,000 today, and you believe it will rise above $140,000 within days. You could buy a call option with a strike price of $110,000. If BTC reaches $140,000 by expiry, you can exercise the option, buy BTC at $110,000, and immediately sell it at market price—locking in a $30,000 profit per BTC (minus premium and fees).
On OKX, this process is automated: profits are settled directly in your account without manual execution.
2. Trading the Option Itself
Instead of waiting for expiry, you can sell the option before expiration if its value increases due to rising volatility or favorable price movement. For instance:
- Buy a BTC call option when the mark price is ₿0.0007
- Sell it later when the mark price rises to ₿0.001
- Capture the spread as profit
This strategy enables traders to capitalize on short-term sentiment shifts without holding until expiry.

Step-by-Step Guide: Buying & Selling Options on OKX
New users can leverage OKX’s Option Simplified interface for quick access to curated contracts.
How to Buy a Bitcoin Option
- Open the OKX app and tap the menu icon (three lines) in the top-left.
- Navigate to Trade > Options Contract.
- Select Option Simplified.
- Choose BTCUSD or ETHUSD; green arrows indicate call (bullish), red for put (bearish).
- Pick your desired strike price—the system recommends available contracts.
- Enter quantity and confirm purchase.
Understanding Contract Size & Mark Price
- BTC Option: 1 contract = 0.01 BTC → Order sizes must be multiples of 0.01
- ETH Option: 1 contract = 0.1 ETH → Order sizes in multiples of 0.1
The mark price reflects real-time valuation of the option and fluctuates with market sentiment. Your total cost is roughly calculated as:
Spot Price × Mark Price × Quantity
For example:
- Spot BTC = $106,000
- Mark Price = ₿0.0007
- Quantity = 0.3 contracts
- Estimated Cost ≈ $106,000 × 0.0007 × 0.3 = $22.26 (plus fees)
OKX automatically computes this as “Estimated Cost” once you input the amount.
How to Sell (Close) Your Option Position
Since option values change dynamically, you can close your position anytime for a gain or loss:
- Go to your active positions.
- Review open average price, current mark price, and unrealized P&L.
- When satisfied with profit (or ready to cut losses), click Close Position.
- Funds settle instantly.
Example:
- Buy 0.03 BTC call at mark price ₿0.0022 → Cost: ~$7.67
- If mark price rises to ₿0.003 → Value: ~$9 → Profit: ~$1.33
- If mark price drops to ₿0.0018 → Value: ~$5 → Loss: ~$2.67
This flexibility makes options ideal for tactical plays on volatility and momentum.

OKX Options vs Perpetual Contracts: Key Differences
While both are derivatives, their mechanics differ significantly:
| Feature | OKX Options | OKX Perpetual Contracts |
|---|---|---|
| Obligation to Settle | No – optional exercise | Yes – positions auto-settled |
| Underlying Assets | BTC, ETH only | Wide range including altcoins |
| Margin Required | No | Yes – subject to liquidation |
| Maximum Loss | Fixed (premium paid) | Variable – depends on leverage |
| Liquidation Risk | None | Yes – under adverse moves |
| Leverage Mechanism | Built-in via premium efficiency | Adjustable leverage (e.g., 10x–125x) |
| Fees | Premium + trading fee | Trading fee + funding rate |
Options suit those wanting capped risk; perpetuals appeal to aggressive leveraged traders comfortable with margin management.
