Trading Post

Description
The Trading Post is a Tier 2 Amenities & Services Building which provides mercantile services for the player Settlement. After construction, periodically  travelling Merchants from outside villages will visit the player Settlement and the player can trade with the Merchant by clicking on the Trading Post.

Upgrade Information
A Trading Post may be upgraded to a Trading Center for a one-time cost of 50 Bricks, 500 Gold Ingots, and 80 Wood Planks.

Basic Strategy
The Trading Post is crucial for Resources otherwise unavailable or rare, and is one of the best ways to accumulate wealth for the player Settlement.

There are several actions available to the player in the Trading Post:
 * Transfer Resources
 * Transfer Gold
 * Upgrade
 * Keep In Stock
 * Buy/Sell

In order to complete any Buy/Sell action, you must have Gold stocked in the Trading Post and along with any Resources. The Trader's responsibility is to stock the Trading Post, and the player may choose to keep an item always in stock.

During a visit from a Merchant, there will be single or a double red arrow pointing down, or a single or double green arrow pointing up. This is an indicator of relative market price at which the Merchant is trading. There will be on either side of the button with a Gold Ingot pointing left, right, or both directions:
 * Pointing left: Merchant is selling
 * Pointing right: Merchant is buying
 * Pointing both directions: Merchant is buying and selling

Occasionally, more than one Merchant simultaneously will visit the player where arbitrage is possible.

Food does not spoil in the Trading Post.
