Trade: buying and selling goods
What blocks a sale?
Add sale goods and quantities to the Trading Post’s plan, allow imports and wait for delivery. Once the caravan is gathered in meeting state, choose both sides’ goods on the trade tab. Manual trade uses current post and caravan stock.
How do I buy goods?
Once the caravan arrives, choose goods and quantities from its inventory and confirm the totals. Cover the difference if purchases cost more than your sales.
Does the purchase quantity apply to each trade?
The current game treats the purchase field as a maximum per trade, without subtracting post stock. Set 100 with 80 already stored and this trade may still buy up to 100. Caravan stock, available sale value and the global buy limit also apply. Purchases follow list order from top to bottom.
Why has automatic trade stopped?
| Setting or state | What to check |
|---|---|
| Purchase timing | Choose on arrival or before departure; automatic trade runs at the selected event. |
| Global buy limit | Before purchase, counted stock at or above the limit blocks buying; 0 means unlimited. It does not trim this purchase to the exact remaining limit. Excluded post stock is added back for this check. |
| Minimum accepted bargaining | Applies to the caravan’s offer for goods you sell or use to pay for purchases. An offer below the setting excludes that item; it does not directly cap the caravan’s sale price. |
| Post goods and funds | Automatic sale needs the item in planned stock and actually stored. Insufficient sale value reduces or blocks purchases. Automatic deposits/withdrawals can fetch silver from the bank. |
| Storage space and indoor placement | Automatic trade stops when post storage is full. Trading Posts and Border Trade Outposts also require indoor placement for automatic trade. |
Does the sell limit protect goods already at the post?
At or below the sell minimum, further sale deliveries stop; 0 means no minimum. If the post is excluded from global statistics, goods already there can still be sold automatically. If it is included, automatic trade checks the minimum and also stops selling.
Why is the price different from the encyclopedia?
The encyclopedia shows base prices; caravan buy and sell bargaining produce separate quotes. A wise lord can reduce non-currency purchase prices. Outdoor Trading Posts and Border Trade Outposts double the manual purchase total and disable automatic trade.
