Revocation is also a way of entrustment and declaration. The non-trading time entrustment function has nothing to do with the reception of the exchange host, that is, the orders entrusted overnight or at noon are also declared by the securities company after the trading system is opened, and the declared orders are related to the securities company system. Investors' doubts about the non-trading time entrustment function shall be explained and explained to investors by securities companies.

During non-trading hours, all orders (including orders and cancellations) remain in the counter system of securities companies. Whether the investor's entrustment can be revoked depends on whether the counter system of the securities company can cancel the entrustment during non-trading hours. Some securities companies do not have this function and can only provide simple "inventory" services, so the entrustment of investors cannot be revoked.
