Test orders are simulated; nothing is booked. A new `trigger_price`, a new `quantity`, or both, under the placement's rules. Only a `pending` limit can be edited. ## OpenAPI ````yaml /openapi.json patch /api/trading/test/v1/limit-orders/{limit_order_id} openapi: 3.1.0 info: description: >- Place and read bullion orders with an API key.
