When running a search in TruckersEdge, the results displayed will not automatically update with new results unless you set an alarm on the search. To set an alarm, you must first run a search.
You will now be able to set an alarm to see any new load that matches the criteria of your search as it gets posted to the DAT database. Just select the Set Alarm option at the top of the screen.
Once selected, you will get an Alarm Created confirmation message and be able to view your alarms by clicking the Alarms option from your menu.
