What Is the WoW Auction House?
The World of Warcraft Auction House is the in-game marketplace where players post items for sale, browse listings by category, and complete trades without meeting face to face. Every realm runs its own Auction House — Retail commodities pool region-wide across NA or EU, while every Classic realm prices items independently per faction.
Booty Bay Broker tracks live WoW Auction House prices across every supported realm and stores the full price history so trends, weekly rhythms, and listing-quantity shifts are visible in one place. The tracker covers four game versions on four dedicated dashboards:
- Retail Auction House — current expansion data sourced hourly from the official Blizzard Battle.net API, with region-wide commodity pricing for NA and EU.
- MoP Classic Auction House — Mists of Pandaria progression data sourced weekly from TSM, faction-split per realm.
- TBC Anniversary Auction House — Burning Crusade Anniversary data sourced hourly from TSM, faction-split per realm.
- Season of Discovery Auction House — Classic-era seasonal data sourced from TSM about twice a day, faction-split per realm.
Each dashboard exposes a search-and-browse table, category sidebar, per-item detail panels, and price / volume / distribution charts. The sections below tour the data pipeline behind each version, the advanced filters most readers don’t discover on their first pass, and a glossary of common Auction House terminology.
Tracking Classic Markets
Classic auction houses split by faction — Alliance and Horde each maintain a separate listings pool on every realm. The tracker keeps the two markets separate end to end: realm selection, charts, heatmap cells, and shopping cart all respect the faction toggle so you never see a blended Alliance/Horde number that doesn’t exist in game.
Data Pipeline
For MoP Classic and TBC Anniversary, data comes from the TradeSkillMaster (TSM) API — not the Blizzard Battle.net API. Blizzard does not publish a public auction-house endpoint for the Classic progression realms, so every price number you see in the Classic surfaces originates from TSM’s aggregated scan data. The Classic detail panels expose four price metrics side by side:
- Minimum Buyout — the lowest active listing for the item on the selected realm/faction.
- Market Value — TSM’s weighted statistic. It discards outliers on both tails, so one mispriced listing can’t swing the number.
- Average Buyout — the arithmetic mean of all listings. Compare to Market Value to spot a thin market where one big listing skews the mean.
- Listed Quantity — how many units are currently posted. Tiny numbers warn you the price may be noisy; high numbers signal liquidity.
Collection Cadence
TBC Anniversary collects hourly; MoP Classic collects weekly. Each item page shows the exact snapshot timestamp so the freshness of the displayed number is always explicit. Sparse weekly data on MoP is expected — not a bug — because TSM’s scan budget keeps MoP on a slower cadence than TBC.
Connected Realms
Blizzard links low-population servers into connected realm clusters; a single auction house serves the whole cluster. The realm selector auto-groups connected realms so picking any member realm shows cluster-wide data — you never need to search every connected partner individually.
Classic vs. Retail Data
The supported versions share one frontend but very different data sources — Retail from the Blizzard Battle.net API, the Classic versions from TSM. Every chart on the site labels its source, and the sections below describe how the pipelines differ.
Retail Commodities
Retail commodity items (herbs, ores, cloth, consumables, trade goods) are region-wide: one price pool for every NA realm, another for every EU realm. The Retail surface reflects this — swapping between realms on a commodity page won’t change the numbers, because Blizzard serves the same data for every realm in the region. Non-commodity items (gear, recipes, mounts, pets) stay per-realm.
Classic Per-Realm / Per-Faction
Every Classic item on every realm on every faction is priced independently. The tracker respects this: the realm selector is mandatory, the faction toggle is mandatory, and switching either re-fetches the full price series. This is why Classic markets feel noisier than Retail commodities — you’re seeing two small markets per realm rather than one regional market per item type.
Source Badges
Every Classic item page shows a TSM badge near the price statistics. Retail pages show a Blizzard API badge. If you’re ever unsure which source is feeding a chart, the badge is the ground truth.
TBC Anniversary Coverage
TBC Anniversary data collects hourly from TSM. The tracker covers every scanned realm on both factions. Item detail pages show the standard four-metric breakdown (Min Buyout, Market Value, Average Buyout, Listed Quantity) plus a price-history chart with toggleable series, a volume chart, and a price-distribution histogram.
Common Items to Track
TBC’s profession system concentrates demand around a small set of raw materials: Primal Fire / Air / Water / Earth / Mana / Life / Shadow / Might, plus Primal Nether for high-end recipes. Herbalism mats (Terocone, Nightmare Vine, Fel Lotus) and Jewelcrafting rare gems round out the top list. The tracker’s category sidebar groups these under Trade Goods > Elemental and Trade Goods > Herb for quick access.
Cooldown-Driven Markets
Tailoring (Shadowcloth, Spellcloth, Primal Mooncloth), Alchemy transmutes (Primal Might, rare-gem transmutes), and Jewelcrafting daily cuts all lean on time-gated cooldowns. The Professions tab on the TBC AH page cross-references each recipe’s material cost against the crafted item’s current Market Value so you can compare selling raw vs. selling crafted without pulling out a calculator.
MoP Classic Coverage
Mists of Pandaria Classic data collects weekly from TSM. Because the cadence is slower than TBC, MoP charts will show sparser points; this is a deliberate product of the TSM budget split, not a bug. The dashboard timestamp on each item tells you exactly when the most recent scan landed.
Material Interdependencies
MoP’s crafting graph is the most interconnected of any supported version — a price change on Ghost Iron Ore ripples across Jewelcrafting (prospecting), Engineering, and Blacksmithing at once. Living Steel (Alchemist-crafted) feeds Blacksmithing, Leatherworking, and Tailoring’s top recipes. The tracker surfaces these chains through the Professions calculator on the MoP Classic AH page, which lets you walk a recipe tree and see which sub-step captures the most margin on the current realm/faction.
Faction Splits
Like every Classic version, MoP auction houses are faction-split. The tracker’s faction toggle flips every price, chart, and heatmap cell to match — no mental math required.
Season of Discovery Coverage
Season of Discovery data comes from the TradeSkillMaster (TSM) API — never the Blizzard Battle.net API, which does not publish a public endpoint for the seasonal realms. The tracker covers every scanned realm on both factions, with the same four-metric breakdown (Min Buyout, Market Value, Average Buyout, Listed Quantity), price-history chart, volume chart, and price-distribution histogram you get on the other Classic dashboards.
Collection Cadence
Season of Discovery TSM data refreshes about twice a day. Each item page shows the exact snapshot timestamp, so the freshness of the displayed number is always explicit. As with the other TSM-backed versions, a quiet seasonal realm can scan slower when fewer TSM contributors play there.
Faction Splits
Like every Classic version, Season of Discovery auction houses are faction-split — Alliance and Horde keep separate listings on every realm. The faction toggle flips every price, chart, and heatmap cell so the two markets never blend into a number that doesn’t exist in game.
Advanced Tool Features
The core Auction House page covers the common browse/search/chart workflow. The features below are power-user surfaces most people don’t discover on their first pass.
Snipe Filter
The item search combined with the Market Value column lets you filter for listings priced well below their weighted median — i.e. items mispriced by the lister. The tracker keeps enough price history to show whether a listing is genuinely underpriced vs. just part of a thin market where any listing looks off. Volume charts help you sanity-check whether the item is actually traded.
Crafting Chain View
Each profession recipe on the Professions Calculator pages exposes its material list with per-material current prices, so you can trace a recipe up its tree. For recipes with intermediate crafted materials (e.g. Living Steel, rare-gem transmutes), the tracker computes the margin at each step and displays both the intermediate and finished-item prices side by side — the numbers are visible, the interpretation is yours.
Seasonal Overlays
The 30-day and All-Time chart views line up weekly resets, raid tier launches, holiday events, and PvP seasons against price history. The overlay makes it easy to see whether the current price movement matches the pattern from the same period last year or is a one-off deviation.
Cross-Realm Comparison
Items can’t be traded across realms (except through Retail’s region-wide commodity pool), but realm-to-realm price awareness is still useful if you play on multiple characters. Switching the realm selector on an item detail page re-fetches the same item’s chart on the new realm, so you can eyeball the spread in seconds.
Reading Market Signals
The WoW economy moves because individual players post and buy on the Auction House throughout the day. The chart views below surface common price patterns so the underlying movement is easier to read.
Undercutting Cascades
When one seller undercuts, others often pile in — the result is a sharp, steep decline on the 24-hour chart followed by a rapid recovery once the discounted inventory sells out. The tracker’s 24H view renders cascades as a V-shaped dip over a few hours, distinct from the flatter long-term trend line.
Anchoring
The last-seen price shapes what other players expect. When the 7-day chart has been flat at one level for a while, new listings at that price tend to sell faster than listings at other numbers. The flat segment of the 7-day chart surfaces this anchor price at a glance.
Pre-Event Demand
Holiday events, raid tier launches, and PvP season starts all concentrate demand on specific item sets. The tracker’s 30-day view shows the pre-event run-up as a rising slope in the days before the event start date, which is typically labelled on the chart via the seasonal overlay.
Reset Rhythms
Weekly resets move consumable prices on a predictable cycle: materials bottom out over the weekend and peak Tuesday/Wednesday. The 7-day chart surfaces this cycle on a per-item basis so the pattern is visible before the data lands in weekly rollups.
Classic Data FAQ
Quick answers to the questions that come up most often about how Classic data is collected and displayed.
How does Classic AH data differ from Retail?
Retail data comes from the official Blizzard Battle.net API (hourly snapshots). Classic data (MoP, TBC) comes exclusively from TSM. TBC updates hourly; MoP updates weekly. The source badge on each item page shows you the origin in one glance.
What are connected realms?
Connected realms are servers Blizzard has linked so they share the same auction house, guilds, and trade channels. The tracker detects connected groups automatically and shows cluster-wide data when you select any member realm — no need to add every partner manually.
How often does Classic data refresh?
TBC Anniversary: hourly. MoP Classic: weekly. Item detail pages show the exact scan timestamp so you know how stale the number might be. Low-population realms sometimes scan slower because fewer TSM contributors play there.
What is TSM and how is the data collected?
TradeSkillMaster is the most-used auction-house addon for WoW. Players who install the TSM desktop app upload their in-game scan data; TSM aggregates those scans into per-realm statistics and exposes them via an API. The tracker queries that API on a schedule and stores every snapshot so the historical charts keep building over time.
Which Classic versions are supported?
MoP Classic, TBC Anniversary, and Season of Discovery each have dedicated pages with realm selection, faction filtering, category browsing, and full historical charts. Retail (currently the Midnight expansion) is supported on its own page. Additional Classic versions will be added as Blizzard announces them.
Why are Alliance and Horde prices different?
Classic auction houses are faction-split at the engine level — Alliance players only see Alliance listings, Horde players only see Horde listings. The two markets have independent supply, demand, and prices. The faction toggle lets you compare.
Auction House Glossary
Quick reference for terms used throughout the tracker and the wider WoW economy.
A – F
- AH
- Auction House — the in-game marketplace where players list items for sale.
- Bid
- Starting price of an auction. Buyers bid up; the highest bidder wins when the auction expires. Most Retail players ignore bids and use Buyout.
- Buyout
- Fixed price at which a buyer can instantly purchase an item without waiting for the auction to expire.
- Commodity
- A stackable trade good sold on Retail’s region-wide market pool. Classic versions have no commodity system.
- Connected Realm
- Two or more servers merged by Blizzard that share one auction house, guild list, and trade channel.
- Deposit
- Fee paid when listing an item. Refunded on sale, lost if the auction expires unsold.
- Flip
- Community term for the pattern of a single item being purchased and then re-listed at a higher price. Visible on the 24H chart as a short-duration dip followed by a new listing at the prior level.
G – M
- Gold Cap
- Maximum gold a single character can hold (currently 9,999,999g 99s 99c in Retail).
- Listed Quantity
- Total units of an item currently posted on the AH for the selected realm/faction.
- Market Value
- TSM’s weighted statistic that trims outliers. More stable than a plain average — a single mispriced listing cannot swing it.
- Min Buyout
- Lowest buyout among all active listings.
- Median Buyout
- Middle value when all listings are sorted from lowest to highest.
N – Z
- Non-Commodity
- Item sold per-realm rather than region-wide — gear, pets, mounts, toys, recipes.
- Region
- Geographic server grouping. The tracker covers NA and EU today.
- Reset
- Community term for a rapid drop and rebound in the listed-quantity metric, where the lowest listings disappear and new listings appear at a higher price. Appears as a sharp dip + spike in Min Buyout on the 24H chart.
- Snipe
- Community term for a listing priced substantially below TSM’s Market Value. The tracker renders these as outliers on the price-distribution histogram; the Market Value column flags the deviation at a glance.
- TSM (TradeSkillMaster)
- Popular WoW addon and API that aggregates auction house scans. Data source for Classic versions on the tracker.
- Undercut
- Listing an item slightly below the current lowest listing so your auction sells first.
- Wall
- Large quantity of an item listed at one price. On the price-distribution histogram, walls appear as a tall bar at a single price bucket with the rest of the distribution clustered above it.
