History: Trade
Version #13 · Compared with the previous version
+ # Trade
+ The **Trade** mod turns a chest with a sign into a shop. There is **no currency**: goods are exchanged for goods, and prices are whatever the market agrees on.
+
+ ## Opening a shop
+
+ 1. Place a chest, a double chest or a barrel.
+ 2. Put a sign on it (or on a block touching it) and write `[Shop]` on the first line.
+ 3. A window opens: put a sample of the **product** in one slot and one or two **price** items in the others, choose *Selling* or *Buying* and the amounts, press *Create*.
+ 4. The samples return to your inventory, and the sign rewrites itself:
+
+ ```
+ [Selling]
+ 16 × Iron Ingot
+ for 1 × Diamond Ore
+ YourName
+ ```
+
+ Every player sees the sign in their own language.
+
+ | Mode | The customer | Goods go | The price goes |
+ | --- | --- | --- | --- |
+ | Selling | buys from the shop | from the chest to the customer | from the customer to the chest |
+ | Buying | sells to the shop | from the customer to the chest | from the chest to the customer |
+
+ **Strict match** means the item must match exactly — enchantments, name, durability. It is on by default for tools, armour and filled shulker boxes.
+
+ ## Buying
+
+ - Right-click the sign: you see the product, the price, how many deals are in stock, and the buttons ×1, ×4, ×16 and "as many as possible".
+ - A deal is atomic: everything moves, or nothing does — with a clear reason in chat.
+ - When stock runs out the first line turns grey: *Out of stock* or *Full*.
+
+ ## Where shops are safe
+
+ | Where | Protection |
+ | --- | --- |
+ | Your plot, district or rented shop lot in a city | Nobody else can break or open the chest |
+ | Wild land | None: a shop there is at your own risk |
+
+ Hoppers never take items out of a shop chest, but you may feed goods **into** it with hoppers.
+
+ ## Shop lots: a shop in someone else's city
+
+ A city can rent out rectangles of land — **shop lots** — to anyone, even non-residents.
+
+ 1. Find a `[Rent]` sign and right-click it: you see the price, the period and the highlighted borders.
+ 2. Press *Rent*. The payment goes to the city treasury; you can pay up to 4 periods ahead.
+ 3. Inside the lot you build and place shop chests. You do not become a resident.
+ 4. If the rent runs out, you get a notice and 7 days to move your goods.
+
+ A player may rent up to 5 lots across the world — enough for a chain.
+
+ ## Getting on the map
+
+ Place a **Pointer** block and run `/point create <type>` next to it: a shop, port, farm, sight or service appears on the world map.
+
+ - `/point name`, `/point desc`, `/point icon` — title, description, icon.
+ - It costs a small weekly fee paid from the Pointer's own slot; up to 3 points per player.
+
+ ## Commands
+
+ | Command | What it does |
+ | --- | --- |
+ | `/tshop info` | The shop you are looking at |
+ | `/tshop list` | Your shops: coordinates, product, stock |
+ | `/tshop log` | Deals in your shops for the last 7 days |
+ | `/tshop trust <name>` | Give someone access to your shop chests |
+ | `/tshop find <item>` | The nearest shops selling the item, with prices |
+
+ ## During a war
+
+ In an attacked sector trade is paused for the battle window. Broken shop chests are restored afterwards together with their contents. See [[war]].
