Please visit:/ View real-time rule details on trade market/info/spot. Regarding call auction The launch of NAVX/USDT spot trading 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, (1) during the call auction period, we limit the total amount of buy orders for a single user, with a maximum buy quantity of $50000 per user; (2) During the last five minutes of the call auction, users can only place limit orders and are not allowed to change or cancel orders. 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.
