Step 6: Watch order status​

Limit vs market behavior

Orders are placed as limit orders. If your limit price is marketable, it fills immediately. If it is away from the best bid or ask, the order rests on the book until matched or canceled.

  1. If the order rests, it appears as open on the main page
  2. If it fills, it moves to the top of the main page
  3. Open the portfolio or positions view to confirm the new position and updated balance
