Trade Capacity

[Finarfin]

How do you increase your trade capacity? I build Trade Depots which tells me that the base now has a trade route available but my capacity is still at 3 of 3.

iirc, the rule is 1 trade route/depot/city plus one more every 10 pop/city, i.e. 2 at 10 pop, 3 at 20, and so on. routes are not tallied globally but per city.

[Finarfin]

So it's not the amount of Trade Depots you have but the populations of your cities?

[Gonzo_o0]

Wiki: "The number of trade routes available increases with the city's population: 10, 22, 34, 48, 62, 78, 94, 112, etc. (every second plus add another 2 turns)."
So i made a little mistake but it was fairly close anyways. And you still need a Trade Depot if i'm not mistaken.

Again, that`s per city, not global. You need to assign trade units specifically to the cities with open trade routes. So when city 1 is at 2/2 trade routes (visible within the city screen) and you are prompted that another trade route is available, it's probably in city 2 or 3 or w/e. You can cycle through the city screens to quickly check or open the Trade Route Overview (bottom-right of the UI) window to get the info.

I'm still a bit confused. I have about a dozen cities all with trade depots, yet I still only have 5 trade routes. Some of the cities are over size 10 giving more than 1 just by themselves. Maybe I'm just misunderstanding how a city's initial trade route gets created.

It may be the behavior of a specific mod you have enabled that changes the trade mechanics. The way you describe it, it looks like Civ 5 behavior. Just to make sure, you did produce trade units to fill those slots, correct?

[Finarfin]

Yes. I have active trade convoys for all 5 available slots. I guess it could be the major overhaul mod I'm using, but I don't think it addressed any trade behavior.

If you're talking about Codex, then yes. It's a resource implemented by my mod.

Trade Capacity is a Resource that globally limits the amount of Trade Routes you can have, while Trade Route Slots (the vanilla thing) is a Resource that limits the amount of Trade Routes each city can maintain.

You're not expected to have enough Trade capacity to use all Local Trade Route slots you have available, instead, use trade routes where they're needed the most.

More Trade Capacity can be gained in a number of ways, including a Policy (or two, don't quite remember), some National Wonders (Central Trade Hub), and some buildings, most notably probably the Avatar, a building that has a Purity-Requirement but no local requirements, allowing Purity-Focused empires to get an extra Trade Route per city with some investment.

Every city that you specialize as a Power Grid will also increase your Trade Capacity by 1.

Thanks, Ryika, for the input. It all makes sense now. Great mod by the way!

Thanks for the clarification Ryika.
