Announcement from Ouyi on Supporting Payment of Spot Transaction Fees with Pricing Currency To further enhance the user trading experience, Ouyi now supports spot orders in the buying direction to be paid in the pricing currency for transaction fees. In addition to the default option of "deducting transaction fees from the currency of purchase", a new option of "paying transaction fees in the currency of expenditure (pricing currency)" has been added to ensure that the amount of currency purchased by users is not affected by transaction fees. Special note: The deduction logic of transaction fees for selling direction orders remains unchanged and will still be deducted from the pricing currency received by the user. Scope of application and operating instructions *Web and App users: Please go to the trading account settings page to view and configure. *Web version: * App: *OpenAPI user: Please call the POST/API/v5/account/set fee type interface to set it up. Function details *Online date: September 23, 2025 *Payment method for handling fees *Pay in the "received currency": The handling fee is deducted from the currency received from the purchase. *Payment in "Expenditure Currency": The currency of the transaction fee is paid separately, without affecting the amount received in the currency of the purchase. *Return commission on pending orders *The currency of the commission received by the hanging party will be consistent with the currency of the commission paid by the eating party. For example, if the customer chooses to pay the transaction fee in the pricing currency during the purchase, the corresponding commission for the pending order will be issued in the pricing currency. *Attention: *The setting of payment methods for transaction fees takes effect in the sub account dimension. *When there are pending spot orders that have not been executed, switching the payment method for transaction fees is not supported. Example (Buy 1 BTC for 100 USDT at a rate of 1%) *Option A: Payment in "Received Currency (BTC)" Expenditure of 100 USDT; Transaction fee=1 BTC x 1%=0.01 BTC; Received 0.99 BTC. *Option B: Payment in "Expenditure Currency (USDT)" Expenditure of 101 USDT; Handling fee=100 USDT x 1%=1 USDT; Received 1 BTC.
