**[OKX Has Discontinued Isolated Margin Trading Under Cross-Margin and Portfolio Margin Account Modes]** To maintain trading stability, OKX no longer supports isolated margin trading under cross-margin and portfolio margin account modes. Please refer to previous announcements for more details. If you still hold isolated margin positions under the aforementioned account modes as of October 13, 2025, we will migrate the relevant positions to a new sub-account named "IsolatedMarginMigration." This sub-account operates under the contract mode, and the trading experience in this mode is similar to that of cross-margin and portfolio margin account modes. If you wish to continue using isolated margin trading, you can switch to the contract mode. Please refer to the product documentation for more details. OKX Team October 10, 2025
