OKX US plans to cancel open orders and trading bots left on affected dollar trading pairs when it retires those order books on Sept. 30. Positions in Grid and Smart Portfolio bots on the affected pairs will also be sold, the exchange says, making inaction potentially costly for traders using those strategies.
According to the US customer notice, the corresponding USDC pairs have been available alongside the affected USD pairs since Sept. 23. Traders have until the migration to cancel open USD-pair orders, stop those bots and recreate them on the USDC pairs. Orders and bots created on the replacement pairs during the parallel window will keep running afterward.
What the deadline changes
OKX US says the old books will be retired between 3 and 4 a.m. Eastern time on Sept. 30, equivalent to 7 to 8 a.m. UTC. All remaining orders and bots or automated trades on affected USD pairs will be canceled. OKX's migration schedule says bots using those pairs may close gradually over that hour and the relevant USD pairs will be delisted at 8 a.m. UTC.

The cancellation has different consequences for the positions behind different bots. OKX says it will sell positions in Grid and Smart Portfolio bots. Positions managed by DCA, Recurring Buy and TWAP/Iceberg bots will be held after migration, although those bots will still close. An automatic sale may incur trading fees or slippage and produce a realized gain or loss; the outcome depends on a user's holdings and execution.
The migration concerns selected USD trading pairs, not every dollar market on the exchange. USDT-USD is exempt. OKX US says account balances, deposits and withdrawals are unaffected. The announced sales concern the specified bot positions rather than a broad sale of customers' funds.

The change also does not eliminate dollar funding for the consolidated book. OKX US says users will still be able to place orders with USD, which will automatically convert to USDC to access the new liquidity. That distinction matters for traders who assume a dollar balance itself must be exchanged in advance: the action required under the notice is to move affected open orders and bots to the corresponding USDC pairs.
For an affected trader, waiting until after the window means losing the existing USD-pair order or bot rather than having it transferred automatically. Moving it during the parallel period preserves control over when it stops and how any Grid or Smart Portfolio position is handled before OKX's scheduled closure.
