AccountOrderUpdate Event

public event AccountOrderUpdateEventHandler OrderUpdate

Public Event OrderUpdate As AccountOrderUpdateEventHandler

Value

Occurs when an order, or multiple orders, are added to this account. This can either be from orders being created and submitted by this API instance, or in response to another API instance submitting orders for this account. It is also called during the initial account load following subscription to the account.

Note: In some rare circumstances (mainly during server disconnects) it is possible to receive the OrderUpdate event for orders that you have not received an OrderAdded event for.
