Worth knowing about each
Interactive Brokers

- IBKR allows one active login session per username. Logging into TWS or the IBKR mobile app with the same username can interrupt automated orders.
- The North America API reset window is 23:45–00:45 ET. Signals in that window can fail even with retries.
