Enable Cancel On Disconnect for the connection. After enabling, all orders created via this connection will be automatically cancelled when the connection is closed.

Cancel is triggered in the following cases: when the TCP connection is properly terminated, when the connection is closed due to 10 minutes of inactivity, or when a heartbeat detects a disconnection. To reduce the inactivity timeout, consider using public/set_heartbeat.

Note: If the connection is gracefully closed using private/logout, cancel-on-disconnect will not be triggered.

Notice: Cancel-on-Disconnect does not affect orders created by other connections - they will remain active! When change is applied on the account scope, then every newly opened connection will start with active Cancel on Disconnect.

Scope & transport:

• scope=connection (the default) applies to the current WebSocket connection only and is available over WebSocket only. Over REST/HTTP it fails with 10030 (must_be_websocket_request), so HTTP clients must pass scope=account.
• scope=account changes the account setting, works over both WebSocket and REST/HTTP, and requires the account:read_write scope. Connection scope only requires an authenticated connection.

Restrictions: Not available for retail broker main accounts or their subaccounts: error 14021 (not_allowed_for_retail_brokers) is returned for both scopes.

Scope: account:read_write (only for scope=account)
