Repeated subscription of new shares was doubled. Why can't I cancel the order?

The announcement of the issuance of new shares clearly stipulates that the subscription of new shares cannot be withdrawn. When new shares are priced or issued by competitive bidding, investors make mistakes, which leads to repeated subscription of the same shareholder code for many times. The exchange computer host not only accepts and confirms the entrustment instruction of initial subscription of new shares, but also automatically cancels the subsequent repeated subscription. On the day of subscription according to market value (T, usually Saturday), the entrustment instruction of repeated subscription of new shares is also accepted, but the entrustment instruction is not confirmed. After the subscription of new shares is completed, it will be treated as "invalid entrustment". Therefore, most securities business departments set up the counter entrustment system in this way: investors repeatedly apply for new shares, and they repeatedly freeze the subscription funds for new shares. If an investor finds an operation error during trading hours, he can immediately report it to the staff of the business department and ask them to manually "unfreeze" the repeatedly frozen subscription funds for new shares.
