TWS Download open orders on connection setting

Quick answer

Download open orders on connection helps expose order details when an API client connects. Review it with the app’s startup behavior. Receiving an order record does not automatically grant the client permission to change that order.

Step by step

1 Open Global Configuration → API → Settings.
2 Locate Download open orders on connection and record its current state.
3 Compare the setting with the app’s documented startup requirements.
4 After a controlled reconnect, compare the app’s order view with TWS working orders.
5 If orders are missing, check client scope and binding behavior with the app provider.

A practical example

An app starts after an order was already placed. It needs to learn what is working so it does not act on an empty view. Check whether its startup flow receives the expected order list. But keep two questions separate: can it see the order, and can it change the order? The first does not prove the second. Ask the app provider about its client scope if the list is incomplete.

How to confirm the result The app should receive the order details its supported workflow expects at startup.

Mistake to avoid

Do not assume every client sees or controls every account order simply because this box is checked.

Common questions

Does this place new orders?

It concerns order details on connection, not a new trading instruction.

Is viewing the same as changing?

No. Ownership and binding rules can still restrict changes.
