The ICommand type exposes the following members.

	Name	Description
	AppSoftware	Name of 3rd party application that placed this command
	ExchangeOrderID	Exchange Order ID or null for cancel commands
	ID	Command identifier

	ResultComments	Comments of (unsuccessful) execution
	ResultTimestamp	Timestamp of execution, UTC
	State	Current command state
	SubmissionType	Was this order manually executed?
	Timestamp	Command creation timestamp, UTC
	Type	Current command state
	TypeState	Gets the verbal interpretation of state depending of type for example "Created", "Modified", "Cancelling", "Cancel failed" etc
	Version	Associated version (for create/modify command) or null - for cancel commands

Top During the lifetime of order, user can control it by sending commands.
Create command is associated with initial Version of order and created when client sends a new order.
Modify command also have new version of order, but cancel command does not.

When command is sent to server, it has Sent state. The state then could be changed to Failed, meaning that command was failed by the reason found in ResultComments property, or to Executed - meaning that command succeed. in both cases, ResultTimestamp property will updated with execution/failure timestamp.
When cancel command succeed, order becomes Cancelled or Completed - depending of number of active fills.
If the modify command succeeds, current order version is replaced, and variable order properties, such as quantity or price will be updated.
