OKX to update the settlement price calculation rule for Dual Investment

Dear OKX Users,

Due to an adjustment to OKX's settlement price calculation rules (please refer to: https://www.okx.com/help/okx-announcement-on-the-adjustment-to-the-calculation-method-of-delivery), the settlement price calculation method for Dual Investment products will be updated accordingly starting March 18, 2026.

After the adjustment, the relevant price will be calculated as the average of the index prices during the last 30 minutes prior to expiration. The system will record one price point every 200 milliseconds, and the final price will be determined by averaging all recorded price points within this time window. As a result, the calculation window will be shortened from 1 hour to 30 minutes.

For the avoidance of doubt, 18 March 2026 will be the first day on which the 30-minute calculation window will apply.

OKX reserves the right to make further adjustments to the price calculation methodology with prior notice.

OKX Team
