About Pre-open session
Pre-open mechanism will be used for spot listing of USD1/USDT. The Pre-open period will last for 1 hour.

OKX operates a Pre-open mechanism that allows you to submit buy and sell orders at your desired prices according to certain trading parameters before a new trading pair officially begins continuous trading.

During the Pre-open session, the buyers and sellers submit limit order around the index price, restricted by index price price limit. Buy orders must be lower than index price *(1 + J%) price limit; sell orders must be higher than index price *(1 - J%) price limit.

At the end of the Pre-open session, the final index price is used to cancel invalid orders. Sell orders that are lower than the index price and the buy orders that are higher than the index price would be cancelled.

There will be no execution of the orders during and after the Pre-open mechanism.

Once live trading starts, the uncancelled orders placed during the Pre-open session will be kept in the orderbook.

Please visit OKX Pre-Open Mechanism to learn more about rules.

Following the end of the Pre-open session, OKX will use the last index price at the commencement of continuous trading as the initial price of the trading chart.
