This brief Execution Report comes faster and just indicates that the order was
cancelled. Besides this brief report, the server always sends the last state of the
cancelled order as another Execution Report with Text="notification" and all
details about the cancelled order. <p> **MMP orders:** if the Market Maker
Protection (MMP) order was cancelled by user request the `DeribitMMProtection
(9008)` flag is removed from the notification Execution Report. Presence of the
`DeribitMMProtection (9008)` flag in the Execution Report with status "cancelled"</p>
means that the order has been cancelled by Market Maker Protection (MMP).
