According to the Management Measures for the Operation of Public Offering of Securities Investment Funds issued by China Securities Regulatory Commission, the trading of funds shall be based on the actual trading time. In other words, the selling time of the fund after adding positions is calculated according to the actual selling time, not a specific time point after adding positions. This means that if the fund is sold many times within a period of time after adding positions, the time for each sale will be calculated separately. Therefore, the selling time of the fund after adding positions is determined according to the actual trading time.
