贸易节点是指地图上的76个静态位置，可以使用商人在这些节点中进行贸易交流。贸易节点并不代表特定的省份，而代表一个地区，each contributing its trade value to determine the overall local wealth generated for the node. The node value can be modified by improving base production wealth, trade goods price changes, constructing manufactories or steering trade to and from the node.
As a general rule, controlling more territory in a node helps in gaining high trade power within that node, although this could also be achieved by controlling only provinces with trade modifiers (i.e. estuary or center of trade). Other means of increasing trade power involve sending merchants or a fleet of light ships to the node. Picking certain idea groups or opportunities to increase mercantilism will improve the effectiveness of these methods.
Note:The table below mentions Inland sea even though trade-wise they are not different from other sea-nodes. This is done to mark nodes in which galleys (or transports) can also be used for pirate hunting missions - though, while in mission, these fleets may occasionally arrive at non-inland sea provinces.
