Side effectsCancels one or more working orders.

When an agent should use it​

  • After listing orders and identifying specific stale or orphaned IDs.
  • With explicit user confirmation per id or list.

When an agent should not use it​

  • In bulk on an account that holds open positions, unless the user accepts the protective-order removal.
  • During a journal review or read-only workflow.

Parameters​

Cancel / CancelOrder per id:

{ "account": "Sim101", "order_id": "abc-123" }

CancelOrders for multiple:

{ "account": "Sim101", "order_ids": ["abc-123", "abc-124"] }

CancelAllOrders for everything in one account:

{ "account": "Sim101" }

Response shape​

{
  "cancelled": ["abc-123", "abc-124"],
  "failed": []
}

Example user prompt​

On Sim101, list working orders. Identify any that look orphaned (no matching
position). Show me the proposed cancel list. After I confirm, cancel only those
ids and then list orders again.

Example tool call​

{ "name": "Cancel", "arguments": { "account": "Sim101", "order_id": "abc-123" } }

Common errors​

Safe workflow placement​

ListOrders  →  build proposed list  →  user confirms  →  Cancel*  →  ListOrders

After CancelAllOrders on an account that holds positions, the position may be unprotected. Consider following up with a fresh bracket placement.
