OKX US will cancel open orders and close trading bots linked to selected USD trading pairs when it retires the relevant order books on 30 September. Positions held by Grid and Smart Portfolio bots will be sold if users do not act before the deadline.
The exchange has told US customers that corresponding USDC pairs have been available since 23 September, giving traders a parallel period in which to move their activity. They can cancel open orders on the affected USD pairs, stop their existing bots and recreate them using the equivalent USDC markets.
Orders and bots created on the replacement USDC pairs during that period will continue operating after the migration.
What happens at the deadline
OKX US says the affected USD order books will be retired between 3 and 4 a.m. Eastern time on 30 September, or 7 to 8 a.m. UTC. All remaining orders and bots, including automated trades, on those pairs will be cancelled.
According to OKX’s migration schedule, bots using the affected markets may close progressively during that hour. The relevant USD pairs will be delisted at 8 a.m. UTC.
The effect on assets held by each type of bot will vary. OKX says positions linked to Grid and Smart Portfolio bots will be sold during the process. Positions overseen by DCA, Recurring Buy and TWAP/Iceberg bots will instead be retained after the migration, although those bots will also be closed.
Any automatic sale could involve trading fees or slippage and may result in a realised gain or loss. The eventual outcome will depend on the user’s holdings and the price at which the positions are executed.
The change applies only to specified USD trading pairs, rather than every dollar-denominated market available on OKX US. The USDT-USD pair is excluded. The exchange says customer account balances, deposits and withdrawals will not be affected.
OKX US will also continue to support dollar funding through its consolidated order book. Users will still be able to place orders using USD, which will be converted automatically into USDC to access the new liquidity.
That means customers do not need to exchange their dollar balance in advance simply because of the migration. Under the notice, the required action is to transfer affected open orders and bots to the corresponding USDC pairs.
Anyone who waits until after the migration window will lose the existing USD-pair order or bot, as it will not be transferred automatically. Moving the activity during the parallel period allows traders to decide when their orders or bots stop and how positions in Grid or Smart Portfolio strategies are managed before the scheduled closure.
