etf funds calculate income according to the confirmation date. Etf-linked funds are OTC funds, and OTC funds can be traded at any time. If they are traded during the trading day, the shares will be confirmed on the second trading day, and if they are traded during the non-trading day, the shares will be confirmed on the third trading day. The fund implements T+1 trading, and the trading on the trading day (trading time) is calculated according to the net value at the close of the trading day (there is only one trading price every day), and the share is confirmed on the second trading day, and the income is calculated after the share is confirmed.
