The Trading Post (TP) is the tool that allows players from all worlds to trade with each other. The Trading Post can be considered a physical representation of the Black Lion Trading Company and its functionality within the game. Trades are anonymous and autonomous: players post offers to buy or sell without having to locate a trading partner. The feature (bound by default to ) is accessible anywhere in-game. However, you must speak to a Trading Post Representative to collect items or coins.
Purchases on the trading post must be made using coin and there are two fees applied to sales: 5% of the asking price to list and a 10% tax when the item is sold.
 Selling and Buying
 Preview purchases
You can preview weapons, armor, dyes, and back items sold on the TP. For weapons, you have the option of viewing them sheathed, wielded or on their own (just the model)
There are two ways to access an item to sell the item:
- Right-click its icon in your inventory window and choose, Sell at Trading Post.
- Open the Black Lion panel, , and select the item from the list.
The panel now shows the current values and selling options for all items that currently are in your inventory.
- Meet the highest buyer to sell instantly for the price being set by the currently highest bidder on the Trading Post. Sales are immediate.
- Match lowest seller puts your items on the Trading Post for a price that matches the currently lowest selling price. Your offer will wait for a buyer interested in paying your asking price.
- You can also place a custom offer different from either of the above.
There are a couple of restrictions: the minimum asking price for an item is 1 above the vendor value, e.g. if vendors will pay 24 for an item, you have to ask for at least 25 . In addition, you cannot sell account-bound or soul-bound items.
There are three ways to access an item on the Trading Post to buy the item:
- Right-click an item in inventory and choose, Buy more at the Trading Post.
- Choose the Buy tab on the left side of the Black Lion panel and search for the item.
- Choose the Buy tab and select one of the items listed, e.g. under Most Demanded or Most Traded.
As with sales, you can accept an existing offer (buy immediately) or place a custom offer. The coin required to pay for your order will be removed from your inventory while you wait for your offer to be accepted.
 Transaction notes
- You can review and remove transactions by using the relevant tab in the Black Lion panel (second from bottom, on the left navigation bar).
- The pull down menu defaults to items you are selling. You can also review items you are buying.
- You can also review past purchases and past sales.
- You must be standing next to a Black Lion NPC to pick-up items.
- Your list of items and cash to pick up is limited to several dozen transactions, so you will not always see every possible item (or coin) waiting for pickup. For example, if you buy a stack of jute bolts, you might see one of the following:
- A single line indicating a transaction 250 bolts, e.g. if a single offer can fulfill the entire order.
- 250 different lines, if your order is fulfilled by 250 different players. In addition, you will only see the first 100 transactions; you might need to click take all several times to collect the full stack.
There are two Trading Post fees, both paid by the seller; they total up to 15% of the total sales price.
- A non-refundable listing fee of 5% (minimum 1 ); this is paid when you post and is not returned if you remove the order.
- A 10% tax on successful sales; this is deducted from the amount available at pickup.
- Although both fees are listed in the trading panel, the "projected profit" only deducts the 10% sales tax.
 Fee notes
- Both fees are shown before you press the submit button.
- The listing fee is calculated on the sum of all items posted, allowing you to save small amounts of copper by using rounding to your advantage.
- Both fees are rounded using the "round half up" method, i.e. any fraction of a coin less than x.5 is rounded down to x, and any fraction x.5 or greater is rounded up to x+1.
- Rounding examples
- Selling an item for 29 should generate a 1.45 listing fee; you pay 1 instead.
- Selling an item for 31 costs 2 , i.e. rounded up from 1.55 .
- Selling an item for 30 results in the same profit as selling it for 29 due to rounding: in both cases, you net 26 : the fees are 3+1 in the first case, but only 2+1 in the second.
- Listing two of an item separately for 10 costs more in listing fees than selling them together: you pay 1 twice by listing them separately, but only 1 by listing them together.
 Losing potential earnings
Be careful about listing items so close to the vendor price that the combined fees would reduce your profit below that offered by merchants.
- To quickly determine if you can make more money on the Trading Post, point your cursor at the item, note the vendor price on the popup box, and add that to the listing fee. If that total is greater than the projected profit, you are better off selling to the vendor.
- Players will sometimes sell items on the TP at these lower prices, despite the loss of potential income. Notably those with full inventories might prefer to get slightly less coin as a minor cost to clear out a full inventory, especially when the alternative requires leaving a dungeon or farming run.
- An item worth 99 can be sold on the trading post for 1 , but this yields only 85 , i.e. 14 less from the TP, after deducting 10 for a successful sale and 5 for the listing fee.
- Listing that same item for 1 20 , nets 1 2 , i.e. 3 more than the price the vendor offers (taking into account the 12 sales tax and 6 listing fee).
 Currency Exchange
The Currency Exchange tab allows you to trade gold for gems and vice versa. The exchange rate is measure in coin per 100 gems and determined by supply and demand from players. The average rate for exchange is displayed below along with the 5 day high and low. A graph displays the average price for the past week. There is a 15% transaction fee for converting in both directions. For example, exchanging 1 gives 85 worth of gems while reselling those gems returns only around 72 25 , a net loss of roughly 28%. As the average price is decided by player supply and demand, prices will often change rapidly when new items are added to the Gem Store or there is a demand for coin. Purchasing gems to convert to coin is a common practice for players. The maximum amount of gems that can be traded at one time is 9999.
The Trading Post displays some market trends: Top Value Items, Top Supplied Items, Top Demanded Items and Top Trade Items.

- Before the game launched, ArenaNet announced plans for an offline tool to browse, bid, or cancel offers. However, there has been no mention of this idea since the game went live.
