Clicking on the top sort bar buttons, sorts them based on their respective values. On first click it is descending, on the second click it is ascending.If you hold, you can set the priority of sorts. For example, if you sort by gold and two routes have the same gold yield, you can set what next value it should be sorted by.If you don’t hold shift, and left click on a sort button, it deletes all other sort options (acts like a reset). You can right click on the buttons to delete that option to sort. If you delete all of them, it defaults to sorting based on players.Enabling theoption, will repeat this trade route. By default, the route repeated is the last one the trader made.The problem with repeated route is you would always need to check if the route being repeated is best one or not. The following option solves that problem. By enabling the, the route that gets repeated is always the top one from the sort entries you picked. For example, if you want the highest food, production route from Aachen, sort routes based on that and start a route with this option picked. When the route ends, the trade manager will check again for all routes from Aachen with sort settings you picked when you started the route (in this case, it was highest food and production). The manager, then picks the top destination from that list and begins the route again. So the route repeated is always the best one, avoiding the need to constantly check if the trader was picking the best route or not.Note: The sort settings that are used to repeat the routes are tied to an individual trader. So you can have one with highest food and production, and another with the highest gold, etc.You can cancel the repeated route from the Trade Overview screen, within the My Routes tab.
