Using BOC Securities mobile trading, I successfully bought two stocks in the morning. When I was about to sell them in the afternoon, the sellable quantity turned out to be zero. The reason: the stocks bought that day cannot be sold that day.

The Chinese stock market implements the t+1 system, which means that the stocks or funds purchased by investors on the same day cannot be sold on the same day, and must wait for delivery and transfer the next day before they can be sold; investors sell on the same day For stocks or funds, funds cannot be withdrawn until the next day.

T+1 is essentially a settlement method for securities transactions, and is used for A-shares, funds, bonds, and repurchase transactions. It means that after a transaction is completed, the corresponding securities delivery and capital settlement will be completed on the next business day (T+1 day) after the transaction date.

my country's T+1 system started on January 1, 1995. It is mainly to ensure the stability of the stock market and prevent excessive speculation. That is, stocks purchased on the same day must be transferred to the next trading day. to sell.
