If you would like to edit your order, you will need to cancel the current order and then resubmit it with the updated instructions. If you need to cancel an order, you can do so up until a certain time depending on the type of order you've placed.
- Market orders and Fractional Share orders can only be canceled if the order was placed outside of market hours. Market orders placed while the market is open will complete immediately and show under completed transactions.
- Limit orders can be canceled, only if the trade price hasn't been reached yet.
