Announcement from Ouyi on the Offline of JST Perpetual Contract Dear Ouyi user: In order to prevent market risks and provide users with a good trading experience, Ouyi will regularly take down some perpetual contracts. The specific offline plan is as follows: 1、 Perpetual contract trading Contract Name | Offline Time| JSTUSTT | August 29, 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: *Price limit rules If there is a deviation in the contract price, the price limit rules will be adjusted according to market conditions. Ouyi will continue to provide you with better products and services! Ouyi team August 25th, 2025
