What does "Presubmitted" mean in the Client Portal Order Ticket?

The "Presubmitted" status in the Client Portal Order Ticket means your order is in the IBKR system but being held and monitored by IBKR. One possibility is a market or stop order that will be active during the next Regular Trading Hours session for that contract. You may also see a "Presubmitted" status for a Stop type order that is being held on IBKR’s servers until the stop is triggered. In Classic TWS/Mosaic, the same order status would be described as “Held and Monitored”.
