Glossary

What each word on the site means, in the sense AHledger uses it. Item and market pages link here; the guides put the terms to work.

30 day median: The median of the daily typical price over the last thirty days. It is the baseline the deal finder and the percent-under alerts measure against, because a month smooths out weekend spikes and reset day dips.See 7 day median, 90 day median, Deal
7 day median: The median of the daily typical price over the last seven days. The "vs 7d median" figure on a price card is how far today sits above or below it.See Median, 30 day median
90 day median: The same measure over ninety days, for items whose price moves with the season or a patch cycle.See 30 day median
AHledger addon: The free in-game addon: tooltip prices, a posting helper, a deal finder, crafting margins, bag appraisal, a watchlist with alerts, and the scanner that feeds the site. Addons cannot use the network, so it needs AHledger sync to share scans.See AHledger sync, Scan
AHledger sync: The small desktop app that bridges the addon and the site: it uploads each new scan under your upload key and writes fresh price tables back into the addon folder. The addon works without it; the site does not learn anything without it.See Upload key, Price table
Alert: A rule on one item and one market that fires when a price or quantity crosses a line you set: minimum buyout or median at or below or above a price, median a percent under its 30 day median, fewer than a number listed, or the item appearing on the house at all. Site alerts arrive by email, Discord or browser push, stay quiet while the rule keeps holding, and re-arm once it stops.See Watchlist, 30 day median
Auction house: The in-game marketplace where players list items for other players to buy. Each listing has a buyout price, an optional bid, a quantity, and a duration. Listings that sell pay a cut to the house.See Market, Minimum buyout
Auction house sales speed (liquidity): How fast an item sells on an auction house: sells fast when the current listings would clear in under a day, sells steadily within 3 days, sells slowly within 2 weeks, and barely sells beyond that or with none sold, from the estimated units sold a day. The estimate counts units that leave the auction house before their time runs out, from full scans of the house taken 20 to 60 minutes apart. A listing counts as sold when it is gone from the next scan and the one after, could not have expired yet, nothing cheaper of the same item was left behind (the house sells the cheapest units first), and no new listing of it asks the same or less (that is a seller pulling a listing and posting it again). Scans cannot tell a sale from a cancellation, so this is an estimate. It leans low: a competitor posting cheaper stock can hide a real sale. It is taken over the last seven days, only when enough hours of scans back it.See Units listed, Listings clear in (days of supply)
Binding: Whether an item can change hands. Binds when picked up means it can never be listed; binds when equipped means it can be sold until someone wears it. Only unbound items have auction prices.
Build: One version of Forever. Each build can add, remove, or change items; the changes pages list exactly what moved between builds.
Crafting margin: What a craft sells for minus what its reagents cost at current prices, per craft. AHledger prices reagents at their median and names any reagent with no known price instead of counting it as free.See Reagent, Median
Deal: A listing whose buyout sits a chosen percent under the item’s 30 day median. The addon’s deal finder lists them from your latest scan, biggest saving first.See 30 day median
Faction: Alliance or Horde. Each faction has its own auction house on every ruleset. The two only meet at the neutral auctioneers, which charge a higher cut, so faction prices can drift apart.See Market
Item level: The game’s power rating for gear. AHledger ranks new Forever gear by item level within its class and slot so you can see where a piece sits among its peers.
Listed value: The gold an auction house holds for sale: every listed unit priced at its median in a full scan, added up. AHledger counts an item priced above three times its own 7 day median at that median, and one listed in more than ten times the most it was listed in on any of the previous seven days at ten times, so one absurd listing cannot inflate it. It measures the size of a market, not the gold players hold. Listed value on every megaserver.See Median, Megaserver, Scan
Listings clear in (days of supply): The units listed now divided by the estimated units sold a day: how soon what is on the auction house would sell if nobody listed more. Under a day means a new listing sells quickly; weeks mean it waits.See Auction house sales speed (liquidity), Units listed
Market: One auction house economy on AHledger: a game, a ruleset, a faction, and a region. World of Warcraft: Forever has no realms, so a market is the whole population of one ruleset and faction, for example PvP Horde.See Ruleset, Faction, Realmless
Median: The middle price of all units listed at the time of the scan, per unit, weighted by quantity. Half the units on the house are priced at or below it. It ignores one odd listing at either end, which is why AHledger uses it as the reference price.See Minimum buyout, 30 day median
Megaserver: The single world everyone on one ruleset and faction in a region plays on in World of Warcraft: Forever, which has no realms. Each megaserver has one auction house, so it is one economy; the US, Europe and China have eight each. Every megaserver economy compared.See Market, Ruleset, Listed value
Minimum buyout: The lowest buyout price on any listing of an item at the time of the scan, per unit. It is what you would pay right now for one, and the price an undercutter has to beat. A single cheap listing can drag it far under what most units sell for; read it next to the median.See Median, Scan
New in Forever: An item that exists in Forever and did not exist in Classic Era. The catalog marks them; their only price history is what players have scanned on this site, since no other source has ever seen them.See Build
Price table: The compact set of per-item prices a market’s scans produce, which AHledger sync writes back into the addon so tooltips and the posting helper have current numbers in game.See AHledger sync, AHledger addon
Provenance: The label under every price saying where it came from (an addon scan, the Blizzard API, or the game itself) and when it was observed. AHledger shows a price’s provenance rather than hiding its age.See Stale
Reagent: An item a recipe consumes. Item pages list the recipes an item is used in and the reagents each craft takes, with quantities.See Crafting margin
Realmless: How Forever is built: instead of hundreds of separate realms, every player on a ruleset shares one world and one economy per faction. It is why Forever markets are few and very liquid.See Market, Ruleset
Region: The Blizzard region a market belongs to. Forever opens in the US, in Europe and in China, so AHledger tracks eight markets in each; a market label ends in its region, as in PvP Horde EU or PvP Horde CN.
Ruleset: The rules a Forever character plays under: Normal, PvP, RP, or RP PvP, with Hardcore to follow. Each ruleset is its own megaserver with its own auction houses, so prices on PvP and Normal are unrelated.See Market
Scan: One read of every listing on a market’s auction house by the AHledger addon, taken when a player opens the house and presses Scan or lets the addon scan on its timer. A scan takes seconds and holds item ids, quantities, and prices, nothing about players.See AHledger addon, AHledger sync, Provenance
Stale: A price whose last observation is older than the freshness window for its source. A stale badge means the number is real but old; a new scan replaces it.See Provenance, Scan
Units listed: How many individual units of an item are on the auction house across every listing, not how many listings there are. A stack of 20 counts as 20.
Upload key: A key id and secret created on your account page and pasted into AHledger sync. Every upload is signed with it, so the server knows which install a scan came from and can drop a bad actor without touching anyone else.See AHledger sync
Vendor price: Two numbers from the game data: what a vendor pays you for an item (the floor no auction price stays under for long) and what a vendor charges for it (the ceiling for anything a vendor sells in unlimited supply).
Volatility: How much an item’s daily median moves around its 30 day average, as a percentage. A low number is a stable commodity; a high number is an item that swings, which is either risk or opportunity depending on the side you are on.
Watchlist: The items you follow. On the site it prices them across every market on one page and holds your email alerts; in the addon it keeps its own list with chat alerts.See Alert
