Description

This interface can modify the price and quantity of the order according to orderId or clientOid.

The implementation of this interface is: Cancel the order and place a new order on the same trading pair, and return the modification result to the client synchronously.

When the quantity of the new order updated by the user is less than the filled quantity of this order, the order will be considered as completed, and the order will be canceled, and no new order will be placed.
