The current unsold share of the fund means that there is no redeemable amount and the fund does not trade in real time. T+ 1 transaction is implemented, the fund is redeemed on the same day, and the share is confirmed on the second trading day. At this time, the position will still be displayed in the account, but there is no redeemable share.

Similarly, if you buy a fund on the same day, the share will be confirmed on the second trading day, and the account will show the position on the second trading day, but the sale will wait until the third trading day, so the unsold share will be displayed when you redeem it on the second trading day.
