IBKR overnight trading is not just an Outside RTH box

Quick answer

IBKR has special rules and routes for overnight trades. The Outside RTH box alone does not prove an app can send those trades. Check the product and the app’s documented overnight mode. Then read the route and hours on the actual order.

Step by step

1 Check whether the stock or ETF is eligible for the intended IBKR overnight session.
2 Review the app’s documented support for overnight routing.
3 Inspect the actual route and overnight attributes on the proposed order.
4 Compare Overnight-only with Overnight plus day-session behavior before choosing a workflow.
5 Verify the resulting broker order rather than inferring support from a preset checkbox.

A practical example

Suppose a stock is offered in a broker’s overnight service. You still need the right route and order fields for that service. A box that allows trades before or after the main session is not enough proof. Ask the app provider to show which overnight mode it sends and where you can check that on the order. Use a paper or other supported test to inspect the request. Do not add a field to a webhook just because you saw its name in API code. The app must know how to use that field, and the broker must accept it for that product.

TWS stock Description showing SMART route, NASDAQ primary exchange, currency, contract ID, minimum tick and frozen data status — This stock is an example of the fields to compare. SMART routing and Primary Exchange are separate fields. The observed feed is Frozen and the market is closed; this is not a live-price or trading recommendation.

How to confirm the result The recorded route and session attributes should match the overnight workflow you intended.

Mistake to avoid

Do not manually add undocumented alert fields and assume PickMyTrade forwards them.
