Please visit:/ View real-time rule details on trade market/info/spot. Regarding call auction Baby/USDT spot launch will adopt a call auction mechanism, with a call auction time of 1 hour. Ouyi adopts a call auction mechanism, where you can place an order at your desired price according to established trading parameters before the new trading pair officially starts trading. The trading system will process all submitted orders according to the call auction rules and calculate a reference opening price based on these submitted orders. In order to maintain market order for all users and reduce disruptive trading experience, we (1) limited the total order size of applicable users during the call auction period to a maximum of 50000 USDT; (2) During the last five minutes of the call auction, set a time period during which orders cannot be cancelled or modified. Please visit the OKX call auction mechanism to learn more about the rules. In order to provide more trading information, after the call auction ends, Ouyi will use the opening price of the project party at the beginning of spot trading as the starting price for the transaction. The opening price provided by token project parties is usually based on the project's valuation, and its price is for reference only. The opening price is not determined by the call auction mechanism and will not affect the price at which you place your order. Project Introduction: Babylon supports BTC staking, connecting the BTC secure network with BTC holders and providing users with the largest and most powerful community in the cryptocurrency field. *English full name: Babylon *English abbreviation: BABY *View Babylon prices: https://www. (okx.com)/price/babylon-baby Rules for Baby Delivery of Pre market Delivery Contracts 1. Delivery time Pre market contract delivery will take place 3 hours after the spot market goes online, and the delivery price will be calculated 2-3 hours after the spot market goes online. If there is a change in the spot listing time, the contract delivery time will also change accordingly. Please pay attention to the announcement of any changes in a timely manner. 2. Delivery price *Index price: We will choose current currency pairs from three or more mainstream exchanges as the weighting components of the index. *Delivery price: The arithmetic mean of the Euro Index 1 hour before delivery will be used as the delivery price for the offline contract to deliver all user positions under the contract. As mentioned above, in the event of abnormal manipulation of index prices, the platform may adjust the final delivery price to a reasonable level for delivery based on the actual situation. After the delivery of the contract, users who hold positions with a value greater than $10000 during the delivery of the BABYUSDT contract will be restricted from transferring all assets from their trading account, and normal operations will resume after 30 minutes. The historical commission and billing records of the BABYUSDT delivery contract can still be queried after the contract delivery. If you need to download the records, please go to the "Order Center" on the Ouyi website to download them. Considering that the market may experience significant fluctuations before contract delivery, users are advised to control risks by reducing their actual leverage or closing positions early. If there is a loss due to overstocking during delivery, the risk reserve will be prioritized for compensation. If the risk reserve is insufficient to compensate, the system will automatically reduce the position from users with high profit margins. 3. Delivery rate The delivery rate is 1%, and any adjustments will be announced separately. 4. Price limit rules After the pre market contract is generated: Buy the highest price=Average mid price in the past hour x (1+15%) Sell order lowest price=Average mid price in the past hour x (1-15%) Within 60 minutes before delivery: Buy the highest price=Average mid price in the past hour x (1+5%) Sell order lowest price=Average mid price in the past hour x (1-5%) Middle price=(buy price+sell price)/2, limit price is calculated every minute.
