That is to say, by determining the T day of the transaction, you can determine which one is the net value.
T-day refers to the trading day, weekends and holidays do not belong to T-day (trading day), and T-day is bounded by the closing time of the stock market.
See table:
For example, a fund is subscribed at 20 o'clock on Friday night. According to the above table, the actual T day of subscription is next Monday.
You need to wait until next Monday night to see what the net transaction value is.
When we trade funds, it is impossible to know the net value of funds, which is the unknown price principle of OTC fund trading.
Even if you buy before the market closes on the same day, you won't know until the net value is announced after the market closes.
