How is the settlement price determined for expiring futures?
You can refer to the contract name to identify the expiry date. For example, BTCUSD-26SEP25 means the contract expires on September 26, 2025.
What's the settlement rules?
At expiry, the system calculates the settlement price using the arithmetic average of the underlying index price during the final hour before delivery. All open positions in the expiring contract will be settled at the settlement price. Any resulting profit or loss will be added to your realized PnL.
If there are positions that remain in liquidation and have not been fully closed before expiry, the remaining position will be settled at the settlement price.
After settlement, the realized PnL from the expiring contract will be credited to your account balance, and the contract will be delisted upon completion of settlement.
If abnormal market conditions or potential market manipulation occur near the settlement time, causing significant fluctuations in the index price, OKX may postpone settlement based on actual conditions. Any changes will be announced separately.
What's the settlement time?
Weekly futures settle at 16:00 (UTC+8) every Friday.
