Buy before 3 pm, calculated according to the net value of the day. If confirmed before 3 pm the next day, it is the net value before 3 pm on the day of purchase. Confirm after three o'clock the next day, around ten o'clock in the evening, which should be counted as the net value of two days.

First, let's look at the current fund. According to the investment type, there are six main types of funds: bonds, stocks, mixed, index, FOF, QDII；; According to the investment methods, there are mainly overall investment and fixed investment. First of all, no matter which fund successfully buys before 3 pm on the trading day, the share will be determined according to the net value of the previous trading day on the second trading day; Of course, you may have operated the fund conversion business. In the process of fund conversion, there will be an operation to make up the difference with the money fund.

Under normal circumstances, funds with open trading rules of T+ 1 are bought before the trading day 15:00, accepted successfully on the same day, and their shares are confirmed the next day. There will be no such situation as you said, and the share will be confirmed on the same day. Unless you buy an on-site fund and trade it in real time, you can see the ups and downs on the day of purchase.

Even the handling fee will be deducted when the share is confirmed the next day. So your situation should be the reason for the losses of other funds held that day.

In addition, I will also talk about two kinds of transactions: on-site transactions and off-site transactions.

First, the on-site fund is the behavior that you have to open an account in a securities company and then buy and sell it on related software. This kind of fund is calculated according to the net value when you buy it, and it is the same as real-time trading when you sell it.

Second, OTC funds, that is, those we bought on Alipay, WeChat or Tian Tian funds, are often calculated according to the net value at the close of 3 pm that day. For example, if you buy at any time today, it is calculated according to the net value at the close of 3 pm that day, so the rise and fall of that day has nothing to do with you.

If you find a problem, first see if it is because of the deduction of the handling fee. Secondly, you can respond to the platform of buying funds and keep the data when trading.
