:''"Trade with the universe."''

A '''trade portal''' is an object where many [[items]] can be bought and sold in exchange for [[currency]]. Prices reflect supply and demand, with higher amounts of local influence and smaller amounts of universal influence on prices. They were introduced in [[Game updates/20140402|version 1.5]].

At any given moment at a given trade portal, items will sell there for 90% of the buying price at the same portal at that moment. As prices change and vary between trade portals, there can be trade portals with vastly different prices, allowing a profit to be made. Prices also change over time, so a price may go up or down as time passes. Buying items raises prices while selling items lowers prices.

==Appearance==
A trade portal appears similarly to a [[portal]], except with a golden tint. The trade portal's base block corresponds to the level of the trade portal, and is identical to the corresponding level for a portal.

==Where Found==
[[File:Cave Troll Trade Portal.png|thumb|A trade portal that spawned with a cave troll]]
A trade portal can be crafted at a [[portal]] for one portal, one [[Gold Coin|gold coin]], and 50 [[Time Crystal|time crystals]]. A trade portal may also be found when a [[Cave Troll|cave troll]] is revealed (even in [[world]]s started before version 1.5). Trade portals found near cave trolls will have different price offsets than a newly-crafted trade portal.

==Using==
[[File:Trade Portal Interface.png|thumb|Interface before v1.5.1]]
[[File:Trade Portal Interface 151 HD.png|thumb|Interface in HD with value arrows]]
The trade portal has three options when tapped: Remove, Buy, and Sell.

A blockhead cannot buy, sell, or otherwise use the interface until they have reached the trade portal. At that time, the trade portal interface (shown to the right) will open.

The icon menu across the top, immediately below the window title, can be scrolled left and right. Selecting an icon will display the trade menu associated with it: [[blocks]], [[:Category:Food|food]], [[tool]]s, [[Clothes|clothing]], [[Mining|mined]] materials, miscellaneous, advanced items, and [[Currency|coins]] (exchange). (See above for a detailed list.) The final icon is for upgrades.

The trade menus can be scrolled up and down. Each line shows the item (and quantity), cost (in gold and copper coins), and a button to sell or buy based on what was chosen when the trade portal was tapped. The buy/sell button will be green if the using blockhead has the necessary items in its [[inventory]]. Items unavailable at the trade portal's current level show a "locked" icon and have no cost or buy/sell button.

Tapping a buy/sell button executes that exchange once but does not close the interface. To close the interface, tap outside its window. Transactions are instantaneous and cannot (or need to) be rushed by spending [[Time Crystal|time crystals]] or aborted.

When buying, a blockhead who has insufficient copper coins but more than enough gold coins will have a gold coin automatically exchanged for 100 copper coins and the transaction completed. Purchasing with insufficient gold coins but more than enough copper coins for exchanging will be handled similarly.

The acts of buying and selling affect the listed prices for that item, although the results may not be visible until multiples of the item have been traded. Buying will cause a price increase, while selling will cause a price decrease. Items going for less than one copper coin each will be listed as multiples of the item, indicated by a number superimposed over its icon. Item listings can switch between singles and multiples as appropriate. The passage of time may also cause some prices to change.

Beginning with [[Game updates/20140527|version 1.5.1]], an icon on each item line shows single or double arrowheads up or down or a horizontal line. These associate the listed price with an unspecified standard and indicate whether it is high, low, or normal. The arrowheads are green or red (green up for sell, green down for buy, so green indicates the price favors the player/blockhead). If tapped, a graph of the item's price over the past 24 hours will appear.

==Unavailable Items==
It may be important to recognize that not all items can be bought or sold through a trade portal. These include:
* Any [[Crafting Surface|crafting surface]] usable to make items.
* [[Portal]]s and trade portals.
* Any [[Dye Bench|dyed]] item.
* [[Paint]] and [[Paint Stripper|paint stripper]].
* [[Painting]]s.
* [[Clothes#Reward Clothing|Reward clothing]].
* [[Shark Jaw|Shark jaws]].
* [[Time Crystal|Time crystals]].

==Notes==
As it's possible to acquire [[Copper Coin|copper]] and [[Gold Coin|gold coins]] and even gems by finding [[Golden Chest|golden chests]] near the surface, the introduction of trade portals allow for acquiring various important materials without [[Mining|digging]] deeply.

For improved effectiveness when selling, pay attention to what can be crafted from raw materials and compare that with what the raw materials themselves will fetch. It is typically profitable to do a little crafting before trading. (For example, a [[Chest|chest]] will usually sell for more than a block of [[wood]].) Allow for crafting that creates multiples when comparing.

A look at [[Trade Portal#Mined Materials|the above lists]] reveals it's possible to buy a replacement for the gem used to upgrade a trade portal. Obtaining the gem in the first place requires the same old exploration or meditation methods, though.

The introduction of [[Meditate|meditation]] and the trade portal has left the terms "[[Renewable Resource|renewable]]" and "[[Nonrenewable Resource|nonrenewable]]" somewhat irrelevant in context of the game.
