An entity with the Barter action has a special market interface to buy and sell resources in exchange for other resources.

Example:

        <Actions>
  		<Barter>
 			<Food>1</Food>
 			<Wood>2</Wood>
 			<Stone>2</Stone>
 			<Ore>4</Ore>
  		</Barter>
  	</Actions>

Notes: Exchanging Resources

The Market is used to buy and sell quantities of resources in exchange for other resource types, through the barter user interface.

Resources are traded at a 2:1 penalty. For example, to purchase 100 Food, the player must spend 200 points of another resource type (Wood, Stone, or Ore).

Transfer of resources is instantaneous once triggered; no trade units are required to deliver the traded resources.
