According to the official announcement, Binance will adjust the minimum price precision (i.e., the smallest unit price change) of multiple U-based perpetual contract trading pairs such as HFTUSDT and ETHWUSDT on July 25, 2024, at 14:30 (UTC+8). During the adjustment period, U-based perpetual contract trading and operations will not be affected; API will be updated synchronously, and API users can check the latest price precision of U-based perpetual contracts through GET /fapi/v1/exchangeInfo; existing contract orders will not be affected. After the price precision update, the system will still match orders in the matching system according to the original order price precision.
