Finds items in Guild Wars 2 that can be sold on the trading post for a higher price than the cost of crafting the item.
-
Download the latest release for your platform from https://github.com/t-mw/gw2-arbitrage/releases and extract the zip contents.
-
If running Windows, open Command Prompt or PowerShell from the Start Menu. PowerShell is the better choice on Windows 7+. If running Linux or MacOS, open your terminal application.
-
Navigate to the extracted folder using the terminal application.
-
Run the
gw2-arbitragebinary using the terminal application (i.e. on Windows rungw2-arbitrage.exefrom PowerShell) to produce a list of items that can be crafted and immediately resold for profit on the trading post using materials purchased from the trading post. The prices used assume that you buy materials at the best offer and sell the crafted items at the best bid (accounting for liquidity - see Effects of Low Liquidity), so the only time spent waiting is during crafting. Items with high 'profit / step' and 'profit on cost' values generally produce a higher return for the time invested.
-
Pass an item id as input (e.g.
gw2-arbitrage.exe 11538) to print a shopping list for the item, which considers the total available liquidity for each ingredient on the trading post. The shopping list will also include items that should be purchased from crafting station vendors.
By default the shopping list will assume that you want to produce as many copies of the item as can be profitably sold on the trading post. To limit the number of items that will be crafted a count may also be passed (e.g.
gw2-arbitrage.exe 11538 --count 100will limit the shopping list to producing 100 items). -
Detailed crafting instructions for the item can then be found on https://gw2efficiency.com/crafting/calculator/ or https://www.gw2bltc.com/, with the caveat that these sites do not account for liquidity when crafting large amounts of items. This means that the shopping list and profits shown will not always be accurate, and you may need to adapt the crafting instructions to use exactly the ingredients printed by this tool.
Important: Check that you have the recipe for the item before spending any money. Some profitable opportunities listed by the tool exist because the recipes are difficult to obtain.
Run gw2-arbitrage.exe --help to see all available options, including CSV export.
The shopping list may contain a mix of components (e.g. Trouser Padding) and raw materials required for that component (e.g. Bolts of Silk + Thread). This is because the tool considers your effect on the market when you buy materials from the trading post. For example, after buying enough Bolts of Silk and Thread to craft 100 x Trouser Padding, you may push the price of the materials high enough that it becomes cheaper to simply buy the Trouser Padding already crafted. Similarly, the tool considers your effect on the market when you sell many items. Although most existing tools ignore this effect, not accounting for it results in overestimating profits when crafting and selling large amounts of items.
The first run of the tool can take a while since all items and recipes must be downloaded from the Guild Wars 2 API.
On subsequent runs the tool will use cached versions of the item and recipe databases, stored in the system data directory. The location of the system data directory is printed in the help text for the --data-dir option.
The directory can be deleted to clear the cache or replaced using the --reset-data flag.
