You can put them on any planet after you research them. Each one gives a bonus to the credit income of that planet. Sadly, you can put as many as will fit around a planet (my last MP opponent put up to 5 around most of his planets, now THAT'S an exciting space battle tactic ). The longest "string" of planets that have at least one Trade Port will get a bonus (hover your mouse over the Credits counter at the top of the screen, and it will show a white line of the most profitable routes), and will also show a list of what Trade Ports are giving you credit-wise. Gravity wells that can't be colinzied don't count in figureing the best trade route.

There is no deminishing return on Trade Ports, so, again sadly, spamming as many as you can around planets is a good tactic. But, they do cost quite an investment at first. And you could be attacked with few defences if you spend all that money on Trade Ports (early game).

you could have just played the logistics tutorial which explains all your questions in about 5 minutes.

Of course vasari never needs trade ports since tec already is making the money and will soon be buying resources vasari sells on the black market. It is a win win situation for vasari.



I heard somewhere that every trade port increases total income from each trade port by .1 and it was like that when I used to play TEC and thought they were unbeatable and unbalanced due to trade ports lol. I used to put like 10 trade ports on a desert planet and would get 11.2 income from trade ports from that planet alone.

Your tradeports each produce 0.1 cr/s more for each link in your longest trade route. So one planet with 5 tradeports is nice...but a trade route 5 planets in length with 1 tradeport each will produce 0.4 additional for each tradeport because of the 4 additional planets in your "longest trade route". And of course, a 5 link trade route with multiple tradeports is even better...but it is the length of the route that determines the additional trade income. I think the base for one planet is 1.2 cr/s ?

Anyhow, the good news is, you don't really have to sweat it too much...build them all over the place, more is better, and spend your energy in figuring out how to kill the other guy.
