• If you want to cancel, you can call the Cancel interface
• When the order is reviewed, whether approved or rejected, instant message notifications will be sent through the Asynchronous Notification stream
• Call the Query interface to get order details

• For net asset value queries, see Money Fund NAV Query
• All timestamps in requests and responses are expressed in UNIX seconds by default.
