Worth knowing about each

Interactive Brokers

  • Stocks only. IBKR futures, options, and crypto are not sent through this WebAPI integration, even when those products exist in TWS.
  • 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.
