== Trade value ==

{{iconify|Trade value}} represents the civilian and private-sector economy of an empire as well as the total value of all goods being traded. All pops generate a small amount of trade value based on their living standards, with higher living standard pops generating more trade value, and trade value also being produced by a number of different [[jobs]], such as {{iconify|clerk}}s and {{iconify|merchant}}s. The trade value of a planet is further affected by its stability, level of crime, designation, and other factors. Additionally, small amounts of trade value can be found as deposits on celestial bodies.

Depending on the empire's {{icon|policy}} [[Policy#Trade_Policy|trade policy]], each unit of trade value is converted into {{iconify|energy credits}}, and possibly {{iconify|consumer goods}}, {{iconify|unity}}, or both.

Civilian trade is not available to {{iconify|Gestalt Consciousness}} empires. {{iconify|Corporate}} empires on the other hand are very efficient at generating and exploiting trade value.

The trade value of an empire can be modified by the following:

| {{tradition|mercantile|Marketplace of Better Ideas|iconify}} tradition

| {{tradition|Mercantile|tree|iconify}} finisher

| {{iconify|Trade League}} federation, member

| {{iconify|Trade League||Level 5}} federation, president

The trade value produced on a planet can be further modified by the following:

| {{iconify|Enclave Trader}} or {{iconify|Merchant of Numa}} governor trait

| {{icon|Stability}} Stability under 50

| {{icon|Designation}} Urban World Designation

| flat {{red|-5}}

| {{Planet modifier|Pm_crime|3|w=24px}} Smuggler Activity (Crime Event Planet Modifier)

=== Trade collection ===

{{iconify|Trade value}} is collected by {{icon|starbase}} [[starbase]]s above outpost level. By default, starbases will only collect trade value from the system in which they are built, but their collection range can be extended by 1 hyperlane jump for each [[File:sb trading hub.png|24px|link=Starbase#Modules|trade hub]] trade hub module present; the [[File:Sb hyperlane registrar.png|24px|link=Starbase#Buildings|hyperlane registrar]] hyperlane registrar starbase building also extends the collection range by 1, as does adopting the {{tradition|Mercantile|tree|iconify}}. A starbase with one or more trade hub modules can also have a [[File:Sb_offworld_trading_company.png|24px|link=Starbase#Buildings|Offworld Trading Company]] offworld trading company building, which produces {{iconify|trade value||+2|green}} for every trade hub module on the starbase, up to a maximum of {{iconify|trade value||+12|green}} on a starbase with 6 trade hubs. If the starbase is disabled or occupied, it will not collect trade value until it is restored. All trade value collected by a starbase is sent to the capital system, where it is converted into useable resources as determined by the empire's {{iconify|policy||trade}}.

A trade route is a path that connects a starbase collecting trade value to the capital system and is required for the trade value to be exploited. Each upgraded starbase has one outgoing trade route, which initially connects directly to the capital, but can be manually re-routed to any other starbase (select the base in trade route mapmode, then right-click on the target base to cancel or switch route). If the trade route of a starbase leads to another starbase, the receiving starbase will send both its own collected trade value and the trade value received from the other starbases further "downstream" towards the capital system. The length of a trade route has no direct effect on its trade value, and overlapping individual trade routes are equivalent to consolidated routes, thus the primary use of manually setting routes is to reduce piracy risk. Once the trade value reaches the empire's capital, the capital system must contain a starbase of higher than outpost level in order for the trade value to be converted into tangible resources.

Trade routes have their own map filter showing routes, protection, and piracy.

{{iconify|Corporate}} empires can establish branch offices on planets of other empires if: they have a commercial pact, are in a federation together, are their subject or overlord, or have the Imperial Charter or are the {{iconify|Sovereign||Corporate|pre=galactic}}. {{iconify|Criminal Heritage}} empires can always establish a branch office.

{{iconify|Corporate}} branch offices exploit 50% of a planet's trade value without reducing the planet owner's own profits. For {{iconify|Criminal Heritage}} branch offices, the percentage will instead vary from 25% with 0 {{iconify|crime}} to 75% with 100 {{iconify|crime}}. Trade value exploited by branch offices is converted entirely into {{iconify|energy credits}} regardless of the trade policy. They do not require trade routes.

Trade value can be collected and routed through wormholes, gateways, and L-gates. Starbases with trade hub modules will collect trade value from the other side of a bypass, treating it as one hyperlane jump, as well as systems neighboring the other end within collection range. Trade routes will also be formed through a bypass if the path is shorter that way. 

Lucrative trade always risks attracting piracy. Every trade route that goes through a system without an upgraded starbase attracts {{iconify|piracy|suf=risk}} in that system, slowly growing for 10 years until it reaches 25% of the trade value going through the system. Piracy is countered in three ways:

# All starbases bigger than outposts eliminate piracy in their systems.

# {{iconify|Piracy suppression}}: Fleets automatically decrease piracy for the systems in which they are located when max piracy is less than piracy suppression. As soon as all fleets leave a system, piracy will start rising again. The total piracy suppression of a fleet equals the sum of piracy suppression of individual ships in the fleet. The amount of piracy suppression per ship depends only on the ship's [[ship designer|hull size]], with corvettes being the best and titans being the worst.<br/ >Any fleet can be given the patrol command in order to facilitate player's piracy suppression across their trade routes. A fleet under patrol command will travel from the starting waypoint, through intermediate ones, reaching an ending waypoint, <!--I don't think they stop while on patrol: stopping along the way until current piracy is less than the difference between max piracy and fleet piracy suppression, -->then re-trace the route back and repeat indefinitely. (Starting and ending waypoints can coincide.) In order to set a patrol waypoint on a system, select one or more fleets, left-click Patrol or press P, and then left-click on a system; press Shift + left-click on another system in order to set additional waypoints.

# {{iconify|Trade protection}}: Starbases give a trade protection value representing heavily escorted convoys that cannot be attacked by pirates. A trade protection value ensures that the same amount of trade value cannot be lost to piracy. By default, this trade protection only applies to the system in which the starbase is located, but can be extended by 1 hyperlane per weapon module. Trade protection also does not extend outside of the territory of the empire to which the starbase belongs. A starbase's protection coverage can be seen in trade routes mapmode as the highlighted trade protection icons. Trade protection is lost immediately if a weapon module is queued for replacement; however, trade protection gained with new modules and upgrades is only shown upon monthly refresh. Trade protection is generated by the following:

#* {{green|+5}} for each gun and missile battery module

#* Adopting the {{tradition|Mercantile|tree|iconify}} adds an additional {{green|+5}} trade protection in all owned systems.

#* Level 4 or 5 of Galactic Commerce resolution adds {{green|+25}} trade protection for all Galactic Community members' systems.

#* The Anti-Piracy Initiative Custodian resolution adds {{green|+5}} trade protection for all Galactic Community members' systems.

If piracy is left unchecked in a system, a pirate fleet may spawn and attack the system. The pirate will attack stations, destroying them, as well as the starbase itself. A system succumbed to pirate attack will be occupied by a pirate station. Pirate ships scale in number with the amount of intercepted {{iconify|trade value}}, but their ship modules will never advance beyond tier 3. Destroying a pirate station awards {{iconify|minerals||200}} and {{iconify|energy||100}} energy, scaled by the empire's monthly income.

As the piracy suppression of individual ships stacks, when max piracy is high along a trade route, it is more effective to combine patrolling ships into one big fleet in order for fleet piracy suppression to approach or match max piracy and to reduce current piracy in one system towards a minimal amount at a time - ideally, current piracy in that system will not bounce back too much by the time the patrolling fleet returns; meanwhile, when max piracy is low, vice versa.

Since it is usually more effective have few fleets and each covering a number of systems, high fleet speed facilities suppression of piracy in player's empire, which in turn makes corvettes with their high speed on top of per ship piracy suppression extra effective at suppressing piracy.

If the player has only used the trade hub module in a starbase for trade value collection in early game in order to conserve the starbase's building slots, in late game, as more building slots become available, it can be more efficient to construct a hyperlane register building and swap a trade hub module for a weapons module in order to extend piracy protection while maintaining collection coverage. This also coincides with higher amounts of trade value that requires piracy protection in late game.

Since trade protection extends over wormholes, gateways and L-gates, player can prioritize weapon modules in starbases near wormholes, gateways and L-gates in order to overlap trade protection coverage. This coincides with the need for defense at or near wormholes, gateways and L-gates.

Connecting all trade hubs to the capital using [[Megastructures#Gateways|gateways]] can eliminate piracy by removing unprotected systems from the trade routes.
