Cross Border Trade

Borders with Commercial Pacts produce dynamic Trade Value, which needs to be collected like other Trade Value. Bigger borders produce more Trade Value, and trading with bigger trade network gives you a bonus. The value will fluctuate with time and the fate of your neighbors.

Another country is considered a trading partner if you have a Commercial Pact with them, they are your overlord, they are your subject, you share the same overlord, or you are members of the same federation. Gestalt empires, inward perfectionists, fallen empires, and the great khan are excluded.

Each system gets 2/5/10/20 Trade Value (depending on tech: none/Offworld Trade Companies/Interstellar Economics/Galactic Markets) added to its star, per bordering system owned by a trading partner, affected by the following bonuses:

• Proportional bonus for trading with a bigger network
  
• Long-term bonus +1% trade value per year, reaching a maximum of +200% after 200 years.
  
• +100% bonus if hyper relays connect across the border, and both are connected to their owners' capitals
  
• Bonus equal to your empire's Commercial Pact Efficiency modifier

Border Trade Value is updated only at the start of each month, and when a Commercial Pact is formed. That means changes to borders, canceled Commercial Pacts, etc will not update Trade Value until the next month.

This does not modify the vanilla bonuses from Commercial Pacts; border trade value is in addition to vanilla effects.
