Ouyi Announcement on ZKJ Coin Pair Leverage and Perpetual Contract Offline

Dear Ouyi user: In order to prevent market risks and provide users with a good trading experience, Ouyi will regularly offline some perpetual contracts and leveraged coin pairs. The specific offline plan is as follows: 1、 Perpetual contract trading Contract Name | Offline Time| ZKJUSDT | April 30, 2025 4:00 PM (UTC+8)| When the contract is taken offline, trading of the contract will be stopped, all user pending orders will be cancelled, and the arithmetic mean of the Ouyi Index one hour before the offline will be used as the delivery price for the offline perpetual contract to deliver all user positions under the contract. If there is abnormal manipulation of the index price one hour before going offline, the platform may adjust the final delivery price to a reasonable level for delivery based on the actual situation. The current funding fee rate for 4:00 pm on the day of offline is 0 (therefore, the funding fee for this period will not appear in the billing record), and there will be no funding fee charged when delivering user positions, nor will there be any additional fees such as delivery handling fees. Considering that the market may experience significant fluctuations before the contract goes offline, users are advised to control risks by reducing their actual leverage ratio or closing positions early. After the contract is taken offline, users who hold positions with a value greater than $10000 at the time of delivery of the perpetual contract will be restricted from transferring all assets from their trading account, which will return to normal after 30 minutes. The above perpetual contract historical commission and billing records can still be queried after the contract is offline. If you need to backup the records, please download them from the desktop order center in a timely manner. In order to ensure the smooth offline of perpetual contracts, the following adjustments have been made to the risk control parameter settings for the aforementioned perpetual contracts: 1. Price limit rules If there is a deviation in the contract price, the price limit rules will be adjusted according to market conditions. 2、 Leveraged trading and current lending Leveraged coin pair | Stop borrowing function | Offline time| ZKJ/USDT | April 28, 2025 11:10 AM (UTC+8) | April 29, 2025 5:00 PM~7:00 PM (UTC+8)| Ouyi will suspend leveraged trading and current lending services for relevant currency pairs during the above-mentioned offline time, and cancel leveraged trading market orders. The offline time for each coin pair is approximately 2 hours. Users who have borrowed/pledged coins in the above-mentioned leveraged trading pairs or current lending must repay the coins before the coin pair goes offline. If the borrowed coins are not repaid by then, the system will be triggered to force the repayment. Risk Warning: Due to significant market fluctuations, it is recommended that users close their positions before stopping trading to avoid losses when the system forces coin returns. 3、 Currency discount rate adjustment ZKJ： Before adjustment: Position | Maximum collateral amount | Discount rate| 1 | 6,000 | 0.8 | 2 | 10,000 | 0.7 | 3 | 16,000 | 0.65 | 4+| Increase by 10000 per level | Decrease by 0.05 per level| After adjustment: Maximum collateral amount | discount rate| 0 | 0 | Introduction to Currency Discount Rate: In the cross currency margin account model, assets of different currencies in the entire position can be converted into US dollars as margin. Due to the significant differences in market liquidity among currencies, the platform provides discounts when calculating the actual US dollar value of each currency, in order to balance market risk. Risk Warning: Due to recent market volatility and the delisting process of currency margin, we will gradually reduce the discount rate to 0. During this period, the maintenance margin rate for user positions using this currency as collateral may increase. To prevent forced liquidation caused by rule adjustments, it is recommended that users promptly control risks by closing positions, reducing positions, and adding margin. Reference for details: Discount rates Ouyi will continue to provide you with better products and services! Ouyi team April 28, 2025
