A coloniser tag will have access to multiple nodes more than the other tags, and it will have higher
global trade modifier due to explo-exp sets, meaning it will benefit from nodes without having any
provincial trade modifier: so a slice from the pie without having any provinces at that node. Other tags can increase the number of merchants with trade-set, and any tag can conquer to form trade company to increase the trade range, yet the colonisers can still have higher trade income, especially as the player.
- And the same coloniser tag will enjoy greater trade flow, as the colonised provinces (so, provincial trade modifier) will increase the trade value of their nodes by increasing the local goods produced.
- And (yes, on top of these) the coloniser overlord tag will have even more trade modifier percentage, by 5% global trade power for each colonial subject, on top of the 50% trade power from them. Yes, that is how a tag from Europe can direct the trade from Canton node in China.
Now. When a tag collects from any node other than the home, it not only cuts the trade power by a multiplicative 50% at that node,
BUT for the coloniser tag,
it will also cost the 5%
global trade modifiers from the colonial subjects. The total loss will be severe. This has been the case until 1.30
emperor version, so no idea if it applies to the newer versions.
Whether a coloniser or not, a tag will benefit cumulative 10%
trade power at the home node for each merchant steering the trade; this is also lost when collecting from any other node.
- If the node is upstream of the home node, it will naturally reduce the income at the home node when collecting there, needless to say, as the accumulated steering bonus that the flow streams through each node until reaching the home node is lost.
- If collecting from another node that is streaming to an unrelated node, then that may give marginal increase to the trade income, but it still is not worth it when the run advances, and all tags choose from either the explo-exp sets else the trade-set, and the trade nodes get richer, and etc.
Then why is there a
collect trade function of the merchants?
All right. Fair question.
Again, and an example: if a tag has home node as Siberia, and conquers the Cape region in South Africa, extra collecting from Cape node
may be lucrative, again, emphasis on
may, and the gain will be marginal. The actual problem in this example is:
Why is that tag bothering to conquer Cape? What is the goal in that allegedly glorious strategy? etc. such sardonic questions will remain unanswered, other than painting-the-map. Whatever.
The problem is, the code will run as such. Code-ottos will conquer poland-tag. NO trade value, as trade from there cannot be steered to Constantinople. Code-castile and code-portugal will colonise North America and Canada regions. NIL trade value, as trade from there cannot be steered to Sevilla. Code-england will conquer Gibraltar and Mediterranean islands, as it has even missions thus incentive to do so. NOUGHT trade value, as those nodes do not flow into the Channel node. Etc. Eh. Whatever.
