|
list_orders(status="Open") |
No open orders — nothing was created |
Assistant: The order was rejected — nothing was placed (I verified: no open orders exist).
-
Reason:
ORDER_TYPE_NOT_ALLOWED_CHEAP_ORDER_OUTSIDE_SESSION_WINDOW— the broker doesn't accept market ("Billigst") orders outside the venue's trading hours. It was 00:48 local (≈04:48 CET), and gettex opens at 07:30 CET — about 2h45m away. - Option 1 — wait for the open. The market order can be placed once gettex opens at 07:30 CET. It would execute at the then-current price, which may differ from €2.50.
- Option 2 — place a limit order now. Limit orders are accepted outside the session and would sit in the book until filled. At €2.50 (or a chosen price) it would only fill at that price or better. A GTD limit order needs a validity date, and the €1.00 minimum-quantity surcharge still applies.
Turn 2 — 2026‑10‑28

Notes
- The first attempt on 2026‑10‑27 was rejected with
ORDER_TYPE_NOT_ALLOWED_CHEAP_ORDER_OUTSIDE_SESSION_WINDOW— market ("Billigst") orders are not accepted outside the venue's trading hours. No order was created. - Two 2FA devices are enrolled, so the push had to be routed to a specific device (iPhone 16 Pro) before the order could be submitted.
- The retry on 2026‑10‑28 was accepted and filled within seconds at €2.53.
- The €1.00 minimum-quantity surcharge applies to stock orders below €500 and is large relative to this €2.53 trade.
