If my orders are going to InteractiveBrokers, are the Orders and Portfolio collections:

  1. Read from IB anytime I go to read them?
  2. A copy of what is sent to IB, and will diverge from what is actually in IB if there is any miscommunication? Or if I place an order directly in IB on shares first purchased via my app?
  3. Cached from IB and synced with IB regularly?
  4. Something else?
