I dont like the idea of using 3rd party websites or software to calculate my routes , is there an way of discovering trade routes ingame or is it just trial and error?
You can find a good trade route by using simply your logical thought.
The higher the galactical average of a good, the higher the possible profit margin.
Metals have a very high galactical average.
Metals are sold mainly by extraction economies.
The higher the population, the higher the supply. (and the demand)
So I seek for a high populated extraction system.
I have not found a high populated extraction system in my vicinity.
But I have found a high populated agriculture system with extraction as second economy.
The result : A fantastic trade route with a profit 1,652 cr/t.
Not the best trade route of the galaxy and all logic has some mistakes.
But it proves that there is no 3rd party programs needed.
And there are a few such logics in the game.
