Trading in Dwarf Fortress first occurs in the first Template:L after establishing your fortress, with the arrival of the Template:L Template:L. Trading is a good way to acquire resources that are not available or are rare in the local area. It also allows for more freedom in selecting starting gear or purchase of additional skills for the expedition party, because items can always be obtained through trade later.

Trader is the term used at your Trade Depot to refer to your fortress Template:L when dealing with merchants in a visiting caravan (r - "Trader requested at Depot"). As a Template:L, the term usually only applies to visiting merchants, or to a dwarf whose highest Template:L is Template:L.

Trade Depot

Building a Template:L is a requisite for trade with caravans that arrive at your fortress.

While it may be convenient to build a Trade Depot outside at first, it is usually a really good idea to move it inside or build walls, bridges and other fortifications around it to protect caravans and your goods from animals (guzzlers), Template:L and Template:Ls.

Everything that is on your map belongs to you, except:

• the items of non-fortress members (only if they are alive, when they are dead they belong to you if you claim the items),^[Verify]
• the items that are in trade wagons or on merchant animals^[Verify]
• the items that are on the trade depot (they belong to the caravan until they are moved out of it)

See the Template:L article for more information on how to interact with it.

Trading Flowchart

Suggested trading procedure
				Arrive at fortress location
Create goods								Build Trade Depot
								Check depot is accessible
								Wait for caravan
Set goods to be traded				Wait for caravan to arrive at depot and merchants to finish unloading				Wait for the diplomat (if any) to reach your leader
Wait for goods to be hauled								Turn your leader's labors off so they don't get distracted
								Conduct meetings with the diplomat
Request trader at depot
Turn your trader's labors off so they don't get distracted
		Trade
				Turn trader's and leader's labors back on
				Retrieve bins from depot to reuse

After entering the trade menu, select the items to offer from the right, and the desired items from the left. All caravans have a weight limit which cannot be exceeded, and the allowed additional weight is displayed in the lower right corner. If the acting broker has at least Novice or better Template:L skill, the value of all items will be displayed. Once the proposal is ready, press t to propose the trade, but merchants will not agree unless they make adequate profit. Be sure to use trade, not offer o, as this will make a gift of the selected items. The amount of acceptable profit is determined by the broker's Template:L and the merchant's mood, described below. Merchants may attempt to propose counteroffers if they do not accept the proposal, which can then be accepted, rejected, or further amended by the broker.

With more experienced brokers or pleased merchants, even marginally profitable trades can be successful, and counterproposals can be rejected safely, offering the same trade again. Note however that a low profit margin for the traders may not be desirable - it has been suggested that both export and profit numbers influence the size of next years caravan and, in the case of the dwarven caravan, immigration numbers.^[Verify]

Goods brought by caravans do not have base quality higher than superior, but decorations on a good may be of any quality.^[Verify]

Trading cue colors

• Brown Items have been created (or modified) by your fortress. They can be traded away or offered as a gift.
• White Items were created by another source. They can be traded, but if one of these items has been selected, the entire selection cannot be offered as a gift.
• Purple Items are under a no-export mandate. If they are traded away it will result in disciplinary action (see justice) against the dwarf that brought the item to the depot.^[Verify]
• Green Items have just been gifted to the caravan and they will not trade it back.
• Red Items have been seized from another caravan and cannot be traded as is; you will need to decorate them or turn them into other items for them to become "valid" trading items. However, a caravan from a different civilization will accept stolen goods without changing them first.

Note that containers (barrels, bins, etc) will be displayed according to the origin of the container, not the contents. So a foreign barrel holding locally-produced beer will display as foreign (white). Once you view the container, the locally-made contents are displayed as local (brown).

Merchant mood

If your broker has Novice or better Template:L skill, there will be a line added below the merchant's dialogue describing the caravan's attitude. Their attitude rises with successful trades (especially if they get lots of profit) and falls when you propose deals they don't like.

• (trader) seems ecstatic with the trading
• (trader) seems very happy about the trading
• (trader) seems pleased with the trading
• (trader) seems willing to trade (Default, at least for humans)
• (trader) seems to be rapidly losing patience
• (trader) is not going to take much more of this
• (trader) is unwilling to trade

The happier you make a merchant, the less profit margin he will demand in a trade. If merchants reach the lowest level, no further trade will be possible, and they will immediately pack up and leave your depot. Since annoyed traders are more likely to reject deals, you should be generous in initial negotiations. Skilled negotiators seem less likely to offend traders with unsuccessful deals.

An easy way to capitalize on this mood system is to perform several partial trades. First trade for a few items, offering goods twice the value of the items you ask for (eg, offer 2000☼ for 1000☼ of his stuff). This will likely make the merchant ecstatic about trading with you. Exit the trade screen, unpause briefly, and then return to trading with a vengeance. With the merchant in such a good mood, he is more likely to counteroffer than reject a trade outright.

Seizing items

Pressing s from the trade menu will seize the selected items of the merchant's. If you seize goods from a caravan, the merchant will respond "Take what you want. I can't stop you." and then leave immediately without the seized goods. Items cannot be seized from the dwarven caravan, and other races will not buy goods stolen from one of their caravans (then marked in red) unless they are tricked into asking for them via counteroffer, or the items are "laundered" by decoration or used to create other goods. Seizing goods will hurt diplomatic relations, but is not grounds for an automatic Template:L.^[Verify]

Pressing the seize button while no goods are selected will result in the merchant interpreting your seizure as a joke. This apparently does nothing to benefit or hinder your trading.^[Verify]

As a side note, if you deconstruct your trade depot with a caravan in it, the wagons will be killed and all the caravan's items will drop to the ground, to be readily hauled away by your Dwarves. This does not mark the items as stolen, and the caravan will leave. However, next year's caravan is partly based on the profits from the previous year - so if you are relying on that race's caravans for needed items, you're hurting yourself in the long run.^[Verify]

Another way to steal without marking as stolen is to forbid the trade depot just before they leave, causing them to leave their goods at the depot.^[Verify]

Note that the civilization attached to a particular caravan will keep track of the value of items the caravan was carrying when they set out to trade, and they will compare this value with the value of items they return home with. Regardless of what method you use to confiscate items from a caravan, even if you came to possess the goods through no fault of your own (an Template:L killed the caravaners, for example) the parent civilization may decide that you stole from them and send a Template:L instead of a caravan the following year. It is prudent to take measures to protect caravans visiting your lands!^[Verify]

Offering items

o You can also give away items, as gifts to the leaders of the Template:L you are trading with. This presumably helps relations between yourself and the other faction, though there is not yet a clear correlation between the value of the offerings and the improvement to relations. The exact effects of offerings on trading are unknown but it is believed due to the offerings' net trade value being counted towards the traders' profit, possibly with a modifier (possibly a multiplier of more than 1 as a bonus or less than 1 to compensate for the improved relations)^[Verify], which in turn increases the quantity and variety of trade goods brought by next year's caravan. Also the Template:L usually requires offerings to be made before his arrival.^[Verify] You cannot offer items that were not made at your fortress; the traders do not want your spare goblin harvest clothes.

Note: There are currently no benefits to offering goods to your king; the game developers have stated that this is to be changed in future versions. ("Req174, REASON FOR OFFERING, (Future): There's no point of offering goods to your own king right now.)"

Unless you are looking for fun, under no conditions should you offer or trade items which are wooden or used wood in their creation (glass, for example) to elves, as this will insult the traders, and may cause them to leave or even damage relations enough to provoke a war between you and the elven civilization you traded with. They will be equally insulted by you trading back their wood-related items - their refusal to accept back their wooden items is probably a bug which will be removed in a later release, though this has not been verified. It is also worth noting that in-game the only way to acquire wood is by chopping down trees, so it is likely that the elves have developed a method of growing and acquiring wood without killing trees which will be included in later development.

Miscellaneous Trading Advice

• Several small trades, exiting the trade window each time, will increase the Broker's relevant skills during the early game.
• Food inside the Trade Depot can go bad. Have a food stockpile nearby so you can quickly haul goods inside.
• Thieves and thieving critters tend to follow caravans. Expect assaults and intruders.
• Be careful about asking traders to bring lots of individual lightweight items (such as meat and fish) as it can result in traders taking a very long time to unload their goods. Unless the path to your depot is extremely long, though, this is unlikely to cause significant problems.^[Verify]
• Create your trading depot inside your fort, preferably in the beginning. Place a 3-tile wide path (which must be free of obstructions such as stairways) to the entrance of the fort and line this with traps; this will help to protect the traders and keep the depot close to your supplies.
• All caravans will bring extra food (meat and edible plants) and wooden logs if the supplies of your fortress are low enough, independent of whether or not you requested them. This does not apply in the case that the weight limit is exceeded by (other) items you requested. The supply situation, as observed by traders, is based solely on the number of unforbidden items in your fortress, whether stockpiled or utilized in buildings (such as wooden axles, water wheels, windmills, or workshops); thus, it is possible to trick caravans into thinking your supplies are low by Template:Lding all of your relevant stocks immediately prior to their arrival.

  This also seems to apply to elven caravans bringing Template:L (except that cloth that's turned into Template:L, Template:Ls or Template:L isn't counted). So if you want elven caravans to stop bringing cloth, buy up all the cloth that the first few caravans bring and stash them somewhere.

• Define your trade depot as a burrow. When traders arrive, you can add your broker or another dwarf, perhaps one you want to train in trading, to the burrow. They will head to the depot immediately, and stay there until you remove them from the burrow.

Caravans

Each friendly race will send a caravan per year, linked to one season, which is autumn for dwarves, summer for humans, spring for elves. In rare cases, goblins will show up in winter.^[Verify] However, in the first year only a dwarven caravan will arrive, although it will tend to arrive later than mid-autumn, unlike previous versions ^[Verify]. Caravans will only show up if that race considers the fortress site accessible (as denoted on the embark screen), with the exception of dwarves, who always arrive unless they are extinct.^[Verify] Caravans appear to enter the map from a random direction which does not coincide with the relative direction of the originating Template:L, and they may appear from different directions or z-levels each year. Caravans may leave without trading if it takes too long to reach the trade depot. Caravans with wagons cannot use stairs. Caravans will embark on their journey back exactly one month after their arrival, whether they have succeeded in reaching the depot or not.^[Verify]

Note that if traders or their animals are prevented from leaving, they will eventually go Template:L. ^[Verify] [Verified in 31.16 - Locked-in traders go insane, throw off their clothes, eventually attack a dwarf and are put down]

Also worth mention is the pathing behavior of the entire caravan. If one member of the caravan reaches a block in their chosen path (ie. a raised drawbridge that was lowered when they entered the map) the entire caravan will re-path, instead of encountering the obstacle one by one.

Liaisons

Template:Ls may be sent with caravans to speak to important dwarves. (THEY WILL SPEAK TO THOSE DWARVES! Even if they have to wait by the bed side in the hospital for months after the caravan left.) They will allow you to choose the type of items that your fortress is interested in, and will focus on bringing more of that kind of item on the next caravan (however those items will also be more expensive). They will also present you with a list of the items they're willing to pay more for, which will be effective upon their next arrival.

Trade agreements can be viewed at a later time through the Civilization menu (c). These trade agreements are cleared when a liaison of the corresponding civilization enters the screen, so they are generally not accessible after the caravan has arrived.

Note that if a liaison is prevented from leaving, they will eventually go Template:L. ^[Verify]

Template:L

"Our fortunes rise and fall together"

The dwarven caravan:

• arrives in Template:L.
• carries metal bars, Template:L, weapons and armor, food and booze, and more. Dwarves alone may bring Template:L and steel goods.
• is well guarded.
• sends a liaison who will speak with the Template:L, Template:L, Template:L, Template:L, or Template:L to negotiate an import-export agreement (unless the Template:L is present).
• influences the number of immigrants received (if the caravan leaves intact).^[Verify]
• will not cause sieges when repeatedly destroyed or lost.
• is the only caravan to arrive during a fortress' first year.
• always arrives regardless of embark location, as long as the dwarven civilization is not extinct.^[Verify]
• cannot have its goods seized from the trade menu.
• may not arrive if your civilization lacks any notable figures.

Template:L

A typical elven caravan.

The elven caravan:

• arrives in the Template:L.
• carries Template:L, Template:Ls, various above ground seeds, Template:Ls and their byproducts, Template:Ls, Template:Len goods & Template:Ls, clothing and Template:L, and may carry tame Template:Ls.
• is unguarded.
• does not accept some items in trade:

Elven traders do not like to be offered any tree byproducts. Forbidden items include:

• Template:Len items, and items derived from wood (including Template:L logs), such as Template:L and Template:L
• Items made from clear and crystal Template:L (because Template:L is used in their creation) - green glass appears to be perfectly acceptable
• Items Template:L with any of the above materials
• Template:L shortswords (since they have wooden handles)
• Template:L (made with Template:L)

Offering or trading forbidden items will cause the mood of the trader to drop rapidly, causing them to refuse to trade any more that season and leave immediately. Additionally you will be called uncouth, crude, and barbaric for not understanding their customs.

However, Template:L and Template:L items, even when Template:L is used in production, are acceptable. Items made from Template:L are acceptable, as are all non-wooden plant-derived products such as Template:L and Template:L. Items made of bone (totems too), horn, shell or leather are acceptable, so are meat and fish. You can also transport your goods to the Template:L in a wooden Template:L, as long as you do not try to sell the bin. Living animals are acceptable, as long as the Template:L or Template:L is not made of Template:L.

Be especially careful with reselling decorated items from other caravans, as non-wood/glass items may have decorations of wood or clear/crystal glass. All items that elven caravans sell are also unacceptable to sell back to elves, as the dwarves have no means of proving that they were made in an "elf kosher" way — and all dwarves know that elves have terrible memory.

Template:Ls

The human caravan:

• arrives in Template:L.
• carries metal bars, sand, Template:L, cloth, food and booze, ropes, waterskins, quivers, backpacks, bronze weapons and (too large) clothing and armor, cages and a few domestic animals.
• moderately guarded.

Template:Ls^[Verify]

A goblin caravan may arrive if your civilization is at peace with the goblins.

The goblin caravan:

• will arrive every season, four times per year^[Verify]
• unguarded
• brings mostly food and cloth
• does not send a liaison or a guild representative
• does not make import/export agreements

Destruction

If caravans are destroyed (intentionally or unintentionally), the items may remain for use. Traders caught in a Template:L will flee as if they were attacked, but will leave all the items dropped by the caravan behind. Pack animals carrying items are affected just like a normal tamed Template:L and must be killed in the cave-in for them to drop items on the ground. It is however much more likely that the pack animals will only be stunned or rendered unconscious, and flee shortly after recovering from the hit. Wagons will collapse if caught in a cave-in, leaving all that it was carrying on the ground as a result. Wagons can also be destroyed by Template:L waves coming up onto the shore if you have settled in the appropriate area. The only difference between collapsing under waves or a cave-in is a higher probability of recovering items if the wagon is destroyed by a wave.^[Verify]

While caravans can defend themselves, they don't like being ambushed. An encounter with unfriendly creatures may cause them to retreat and forget about trading with you for the season.^[Verify]
Repeated caravan destruction (intentional or unintentional) will strain diplomatic relations and may result in a Template:L.^[Verify] (sieging verified in .31.12 Genesis-mod)

"By killing a dwarf merchant you started a loyalty cascade. The merchant is a member of your civilisation so his killer became a hostile to your dwarves. However he is still a member of your civ, so the dwarf that kills him becomes a hostile. And so on and so on, I think the only way to finish it is by cutting off contact to the killers until they wipe each other out, or you only have one dwarf left like you do."

Caravan Delay

If a caravan has arrived at your trade depot and is unable to leave for about six months after they arrived, the merchants and animals will go insane. This can result in a bunch of merchants attacking your dwarves, or just standing around moping until they starve to death. It is not known for certain if this hurts diplomatic relations, but most likely it's the same as any case where the entire caravan fails to return home.^[Verify]

If you have locked the caravan into your fortress to hold out against a siege, it's a good idea to station a squad of soldiers near the trade depot in case the merchants Template:L. You may also want to make the depot a restricted area to encourage civilians to go around it. Alternatively, you can design the trade depot using drawbridges, so that it can be sealed off from the rest of the fortress during a siege.

If you want the merchants to leave safely, you can build four or more tunnels to each corner of the map, connected to your fortress only by drawbridges. As long as there is no other way to enter and exit your fortress, invaders and merchants will both go towards any tunnel that you activate. You can lock the merchants into the trade depot, and then open a tunnel entrance on one side of the map to make the invaders head towards that tunnel. When they get close to it, you can close it, and then open the entrance on the other side of the map, and let the traders out of the depot. If your fortress and depot are in the middle of the map, this will give the traders quite a head-start to get away.^[Verify]

Caravan guards cannot be starved, dehydrated, or driven to insanity if prevented from leaving, their employers and animals will however.

Bugs

• No one brings wagons, even if there is a clear path to your depot. ^Bug:197
• Dwarves may try to eat unowned food at the Depot, but realize their mistake halfway and stop... then try again... you can see where this is going. ^Bug:237
• Wild animals cannot be traded; when a dwarf attempts to move the caged animal to the Depot, the creature is set free.Only aggressive animals?
• If your Template:L isn't already stocked with the specified amount of thread/cloth, your dwarves will carry off as much from the caravan as they need to fill it. ^Bug:66
• Caravans show up very late in the season. ^Bug:1756

Exploits

• If you destroy the Depot while they are unloaded you will get the leaving message but they will leave before the building is completely destroyed, so they will not reclaim any of their stuff because it is not available until the building is fully deconstructed. However any animals they had caged will only become friendly, you won't actually own them.

If you wait some time (2-3 months^[Verify]), you can "claim" animals by linking a lever to the cage and opening it, the animals will be released in a tamed state. Check the 'u'nit screen before releasing them; if the creatures still show as Merchant creatures, they will wander off the map when released; if they show as Tame creatures, they will stay once released.
