Markets

Markets hold all the resources an Empire produces on a World. Markets don't exist in any one location, but are more of an overview of the economics of an Empire's territory.
Markets hold Resources, Trade Goods and Crystals. Items can enter a Market through Production or through Trade Routes.
| Resources | |
| Trade Goods | |
| Crystals |
A Market is automatically created when an Empire claims their first Area on a World.
Trade Goods
Populations desire Trade Goods to be happy. Not having Trade Goods available will make Populations unhappy. The demand for Trade Goods is equal to the population's quantity, spread evenly among all 8 Trade Good types. Another way to think about it is:
demand for a particular trade good per hour = total population quantity / 8
Populations will regularly purchase Trade Goods from their Market at their stated Exocredit price, generated Exocredits for their Empire. The price of Trade Goods will change automatically based on Trade Good availability and the Populations' demand.
Market-to-Market Trading
There are two methods of transporting resources between two markets: Trade Routes and Import/Explorts.
Imports/Exports
For each item that a Market can hold, the owner can set an export price, an export amount, an import price, and an import amount. As an exception, the prices of Trade Goods is determined by Population supply-and-demand, so Trade Good prices are set automatically.
The Export Amount sets how much of the item you are willing to sell to other Markets, and the Export Price sets how much any purchasing Empire would pay. If the Market is Open, any other Empire that has this Market in range can decided to purchase some amount of those goods at the listed price.
The Import Amount sets how much of the item the Market owner would like to purchase, and the Import Price is the price they are willing to pay. The Exocredit cost for Imports are taken from the owner when the import is set and stored in the Market. If the Market is Open, any other Empire with this Market in range can choose to sell some of their own goods into this market and receive exocredits.
Imports and Exports do not happen instantly. When an Empire decides to Import into or Export from another Market, they're creating a temporary Trade Route that will operate until the agreed items are delivered, or until there are no more items available.
Because Imports and Exports are fulfilled over time, it's possible for multiple Markets to accept the same Import/Export order, and for it to be fulfilled earlier than either Market expects.
Open/Closed
An Open Market allows any other Empire to fulfill Import or Export orders.
A Closed Market can only be accessed by the Market's owner.
Blockades

When a Fleet controls orbit around the World the Market is on, the Fleet owner can Blockade the planet, preventing Trade Routes from functioning with Markets on the World.
Interdiction

Interdiction is the enforcement of Sanctions. When an Empire has a Fleet controlling orbit around a World, they can have that Fleet Interdict. This will block Trade Routes from working with any Markets owned by an Empire the orbit-controller has Sanctions against.
Piracy
Fleets in the area can engage in Piracy, occasionally disrupting Trade Routes that use Markets on the World at random.
