On 2026-10-13 the 09:53 ET run placed six MOC orders and failed: the paper
account reports MOC orders as PendingSubmit until the closing auction and sent
no acknowledgement within 30 s, so confirm_orders treated them as rejected.
IBKR listed all six with permanent ids and filled them at the close, as it did
the 14 PendingSubmit orders of 2026-09-29. Every retry then stopped at "6 open
orders already exist", and after 15:45 ET at the order window, and the start
limit's 6-hour window reset at 15:50 ET, so the job restarted every 10 minutes
into the evening (42 restarts by 17:28 ET).
- confirm_orders accepts a PendingSubmit order once IBKR lists it with a
permanent id, re-reading this client's open orders every 5 s for up to 60 s.
- rebalance --submit succeeds without sending anything when every open order
comes from today's runs and IBKR still holds every order those runs sent;
a missing one still fails.
- The trade unit skips starts after 15:45 ET (ExecCondition), which systemd
does not restart.
