A list of things you can do to increase trade value of a trade node:
1) Develop provinces (DIP)
2) Production efficiency percentage (% from tech, ideas and policies). It increases the amount of goods you produce.
3) Goods produced modifier (Ideas, traditions). GB, Portugal, Plutocratic ideas, policies and so on.
4) Buildings. Factories add a flat modifier (quite useful on provinces with high autonomy). Counting houses add a flat percentage (%).
5) Steer trade.
6) Being a merchant republic and/or trade company in a node with a significant portion of the total TP.
And that's it.
