Expiry futures are a powerful financial instrument that allows traders to speculate on the future price of cryptocurrencies with precision and flexibility. On OKX, traders can access both crypto-margined and USDT-margined expiry futures, enabling diverse trading strategies based on market outlook, risk tolerance, and settlement preferences. Whether you're hedging portfolio exposure or capitalizing on short-term price movements, understanding how expiry futures work is essential for success in the dynamic crypto derivatives market.
This comprehensive guide walks you through the key aspects of OKX expiry futures, including contract types, settlement mechanics, margin structures, and trading modes — all designed to help you trade more effectively and confidently.
Understanding Crypto-Margined Expiry Futures
Crypto-margined expiry futures on OKX are derivative contracts settled in cryptocurrency, such as BTC or ETH. These contracts allow traders to take long or short positions on major crypto pairs like BTC/USD and ETH/USD, profiting from both rising and falling markets.
These futures come in three durations:
- Weekly
- Monthly
- Quarterly
Each contract has a fixed expiration date, after which it is automatically settled.

Example: BTCUSD Expiry Futures Specifications
- Underlying index: BTC/USD
- Delivery currency: BTC
- Face value: 100 USD
- Contract multiplier: 1
- Tick size: 0.1
- Leverage range: 0.01x – 20x
- Trading hours: 24/7
- Contract types: Weeklies, Monthlies, Quarterlies
- Delivery time: 8:00 AM UTC, every Friday of the delivery week
Because these contracts are settled in BTC, traders must manage their exposure to Bitcoin’s price volatility even after closing positions. This makes them ideal for experienced traders who already hold BTC and want to hedge or leverage their existing holdings.
Exploring USDT-Margined Expiry Futures
USDT-margined expiry futures offer a stablecoin-settled alternative, allowing traders to profit from crypto price movements without needing to own the underlying asset. Settlement occurs in USDT, making profit and loss calculations more predictable and less exposed to cryptocurrency volatility.
Available contract durations:
- BTCUSDT: Weekly, Monthly, Quarterly
- ETHUSDT: Weekly and Quarterly only
This structure provides flexibility while limiting direct exposure to volatile base assets.
Example: BTCUSDT Expiry Futures Specifications
- Underlying index: BTC/USDT
- Delivery currency: USDT
- Face value: 0.01 BTC
- Contract multiplier: 1
- Tick size: 0.1
- Leverage range: 0.01x – 20x
- Trading hours: 24/7
- Contract types: Weeklies, Monthlies, Quarterlies
- Delivery time: 8:00 AM UTC, Friday of the delivery week
USDT-margined contracts are especially popular among beginners and intermediate traders due to their simplicity and stable settlement mechanism.
Expiry Futures Contract Generation Rules
OKX systematically lists new expiry futures contracts to ensure continuous market availability. The listing and expiration rules vary slightly depending on the underlying asset.
| Feature | BTCUSD | ETHUSD / BTCUSDT | ETHUSDT |
|---|---|---|---|
| Available expiries | 7 dates | 6 dates | 4 dates |
| Expiration times | Fridays at 8:00 AM UTC (weekly), last Friday of month (monthly), last Friday of quarter (quarterly) | Same as BTCUSD | Weekly and quarterly only |
| Listing time | New contracts listed at 8:00 AM UTC |
This structured rollout ensures liquidity across multiple time horizons and supports both short-term speculation and longer-term hedging strategies.
Core Features of OKX Expiry Futures
Settled in Crypto or USDT
Choose between crypto-settled (BTC/ETH) and stablecoin-settled (USDT) contracts based on your risk profile and portfolio composition. Crypto-margined contracts are ideal for native asset holders; USDT-margined contracts offer price stability during settlement.
Fixed Expiration Date
Every expiry future has a predetermined delivery date. The final settlement price is calculated by averaging the index price over the last hour before expiration — reducing manipulation risks and ensuring fair valuation.
Reliable Index Pricing
To maintain accuracy, OKX derives index prices from at least three major exchanges. For USDT-margined contracts, the underlying USDT index is used; for crypto-margined ones, the USD index applies. A robust filtering mechanism prevents outliers from distorting the index during flash crashes or pump-and-dump events.
Dynamic Price Bands
OKX implements real-time price range controls based on the average of spot and futures prices from the previous minute. This helps prevent spoofing and other forms of market manipulation by restricting order placement outside normal volatility bands.
Mark Price for Fair Liquidation
During periods of high volatility, OKX uses the mark price — a fair value estimate derived from the index and funding rates — to determine liquidation levels. This protects traders from being prematurely liquidated due to isolated, anomalous trades.
Tiered Maintenance Margin Levels
As position size increases, so does the required maintenance margin. This tiered system reduces systemic risk by lowering maximum allowable leverage for large positions, promoting healthier market conditions and protecting both users and the platform.
One-Way vs. Hedge Mode
Traders can choose between two position modes:
- One-Way Mode: Only one directional position allowed per contract. Selling part of a long position reduces its size.
- Hedge Mode: Allows simultaneous long and short positions on the same contract, giving advanced traders greater strategic flexibility.

Daily Settlement Mechanism
For cross-margin positions, OKX performs daily settlements at 8:00 AM UTC. During this process:
- Realized PnL is credited to your account balance.
- The entry price is updated to the settlement price.
- Floating PnL is recalculated using the new base price.
- No fees are charged, and position size remains unchanged.
The settlement price is derived from the average mark price over the final hour before settlement. This ensures transparency and minimizes manipulation risk.
Note: This daily settlement only applies to cross-margin positions. Isolated margin positions are settled only upon closure or expiration.
Frequently Asked Questions (FAQ)
Q: What happens when an expiry futures contract matures?
A: At maturity, the contract is automatically settled based on the average index price over the last hour. Positions are closed, and profits or losses are credited in the settlement currency (BTC, ETH, or USDT).
Q: Can I hold an expiry futures position past its delivery date?
A: No. All expiry futures contracts are automatically settled at their delivery time. To maintain exposure beyond that point, you must roll your position into a later-dated contract.
Q: How is leverage applied in expiry futures?
A: Leverage is adjustable within a range (up to 20x). Higher leverage increases both potential gains and risks, including faster liquidation under adverse price moves.
Q: What’s the difference between mark price and last traded price?
A: The last traded price reflects recent transactions, which may be volatile. The mark price represents a fair value using external indices and is used for liquidation calculations to avoid unfair triggers.
Q: Are there fees for daily settlement?
A: No. Daily settlement incurs no additional fees and does not affect your position size.
Q: Which margin mode should I use — one-way or hedge?
A: Use one-way if you prefer simple directional bets. Choose hedge mode if you want to run complex strategies like straddles or carry offsetting positions simultaneously.
