Understanding Auction House Prices
A complete guide to reading price data, understanding market trends, and making gold across all World of Warcraft versions tracked by Booty Bay Broker.
WoW Retail Auction House
The Auction House is the central marketplace in World of Warcraft where players buy and sell tradeable items for gold. Every realm cluster hosts its own Auction House, and prices vary based on local supply and demand. In the Midnight expansion, the economy has grown more complex than ever: new Quel'Thalas crafting materials, player housing furnishings, and endgame consumables all compete for attention on the Auction House. Understanding how prices move -- and why -- is the key to building wealth in Azeroth.
Key Price Metrics Explained
Booty Bay Broker tracks several price metrics for every item on the Auction House. Min Buyout is the lowest price currently listed -- this is what you would pay right now if you purchased the cheapest available listing. Market Value is a weighted median calculated from recent sales data that filters out outlier listings, giving you a more stable estimate of an item's true worth. Average Buyout is the arithmetic mean of all current listings, which can be skewed by extremely high or low prices. Listed Quantity shows how many units of the item are currently available, which is an important indicator of supply pressure. When quantity drops sharply while Market Value holds steady, a price spike often follows.
Commodity vs. Non-Commodity Pricing
World of Warcraft Retail divides tradeable items into two pricing models. Commodity items -- trade goods, herbs, ores, cloth, enchanting materials, gems, and other stackable resources -- are sold on a region-wide market. Every realm in North America shares the same commodity prices, and the same applies to Europe. When you search for a commodity on Booty Bay Broker, you are seeing region-wide data regardless of your selected realm. Non-commodity items -- weapons, armor, pets, mounts, recipes, and most equipment -- are sold on a per-realm basis. Prices for these items can differ dramatically between high-population and low-population realms, so always check your specific connected realm when evaluating non-commodity deals.
Using Price History to Find Deals
The interactive price history charts on Booty Bay Broker let you view price trends over 24 hours, 7 days, 30 days, or all recorded history. Look for items whose current Min Buyout has dropped well below their 7-day or 30-day Market Value average -- these are potential buying opportunities. Conversely, if an item is trading far above its historical average, it may be a good time to sell your stock. The Volume chart reveals listing activity: a surge in listings often precedes a price drop, while declining listings can signal an upcoming shortage. Combine price history with the Market Heatmap to spot entire categories that are trending upward or downward, then drill into individual items for precise timing.
Profitable Crafting with the Professions Calculator
Booty Bay Broker includes a Professions Calculator that cross-references current Auction House material costs against the market value of finished crafted items. This lets you see at a glance which recipes yield a profit and which ones cost more to craft than the result is worth. In the Midnight expansion, professions like Alchemy, Enchanting, Jewelcrafting, and Inscription remain central to the endgame economy. Check the Professions tab regularly to identify crafting opportunities as material prices fluctuate throughout the week.
Frequently Asked Questions
How often are Auction House prices updated?
Booty Bay Broker collects price data from the official Blizzard Battle.net API on an hourly schedule. Each update cycle polls every active connected realm in both North America and Europe, so the prices you see are typically no more than one to two hours old. Commodity prices are refreshed on the same schedule but reflect region-wide data rather than individual realms.
What is Market Value and how is it calculated?
Market Value is a weighted median price that represents the typical transaction price for an item. Unlike a simple average, the weighted median filters out abnormally high or low listings that can distort the picture -- such as someone listing a common herb for 999,999 gold. This makes Market Value a more reliable indicator of what an item is actually selling for on the Auction House.
What are commodity items in World of Warcraft?
Commodity items are stackable trade goods that are sold on a region-wide market rather than a per-realm market. This category includes herbs, ores, leather, cloth, gems, enchanting materials, pigments, cooking ingredients, and other raw or processed crafting materials. When you buy or sell a commodity on the Auction House, you are interacting with every player in your region (NA or EU), not just players on your specific realm. This means commodity prices tend to be more stable and competitive than non-commodity prices.
How do I track specific item prices?
Use the search bar at the top of the Auction House page to find any item by name or item ID. Once you select an item, click the star icon to add it to your Favorites list. Favorited items appear in the My Collection tab for quick access. If you create a free Booty Bay Broker account, you can also set Price Alerts that notify you when an item drops below or rises above a gold threshold you choose.
What is the Market Heatmap?
The Market Heatmap is a visual overview of price changes across all item categories on the Auction House. Each tile represents an item, sized by its trading volume and colored by its price change: green tiles indicate rising prices, red tiles indicate falling prices, and gray tiles are stable. You can view changes over 24 hours, 3 days, or 7 days, and switch between views including Overview, By Category, Best Deals, and Fast Movers. The heatmap is one of the fastest ways to spot market-wide trends and find opportunities you might otherwise miss.
Understanding Price Metrics in Depth
Auction House analytics relies on several distinct price metrics, each telling you something different about the market. Knowing which metric to use -- and when -- separates informed traders from gamblers. This section breaks down every metric tracked by Booty Bay Broker and explains how to apply each one in practice.
Min Buyout
Min Buyout is the single lowest buyout price among all active listings for a given item. It represents the immediate cost of acquisition -- the price you would pay if you bought the cheapest listing right now. Min Buyout is the most volatile metric because a single player can post one item at an absurdly low price (intentionally or by mistake) and drag the number down instantly. It is useful for snipe shopping (catching underpriced listings before anyone else does), but it is a poor indicator of an item's true market value because it reflects only one listing out of potentially hundreds.
When you see Min Buyout drop sharply but Market Value stays flat, someone is likely dumping stock or made a pricing error. When Min Buyout rises above Market Value, it usually means supply has dried up and remaining sellers are pricing aggressively.
Average Buyout
Average Buyout is the arithmetic mean of all current listing prices. Add up every listing's per-unit buyout price and divide by the number of listings. This metric gives you a rough sense of the overall price level, but it has a significant weakness: outliers. If 99 players list an herb at 10 gold and one player lists it at 10,000 gold, the average jumps to roughly 109 gold -- far above what anyone is actually paying. For this reason, Average Buyout works best on high-volume commodity items where outliers get diluted by hundreds or thousands of listings. On low-volume items with few listings, it can be misleading.
Median Buyout
Median Buyout is the middle value when all listing prices are sorted from lowest to highest. Half of all listings are priced below the median, and half are priced above. This makes the median far more resistant to outlier manipulation than the average. If that one player lists an herb at 10,000 gold, the median barely moves because it still sits in the middle of the 99 normal-priced listings. Median Buyout is a reliable indicator of what most buyers are actually paying and what most sellers are actually charging.
Market Value
Market Value is a weighted median that goes beyond a simple middle-of-the-pack calculation. It applies weighting based on recent transaction patterns and listing volumes to produce a smoothed estimate of an item's real-world trading price. Market Value filters out both abnormally cheap listings (potential bait or errors) and absurdly expensive ones (price-gouging attempts). This is the metric most experienced WoW traders rely on for buy/sell decisions because it reflects actual economic activity rather than the whims of individual listers. On Booty Bay Broker, Market Value is shown prominently on item detail panels and is the default line on price history charts.
Listed Quantity and Volume
Listed Quantity counts the total number of individual units currently posted on the Auction House for a given item. This is distinct from the number of listings (one listing can contain a stack of 200 units). Quantity is a leading indicator of price movement. When quantity is unusually high relative to the item's historical average, it signals oversupply -- prices are likely to fall as sellers compete to undercut each other. When quantity drops below normal levels, scarcity pushes prices upward. Tracking quantity alongside price gives you a complete picture: price tells you what happened, quantity tells you what is about to happen.
Which Metric Should You Use?
For buying decisions, focus on Min Buyout relative to Market Value. If the current Min Buyout is 30% or more below the 7-day Market Value, you may be looking at a buying opportunity. For selling decisions, price your items near or slightly below the current Market Value -- listing at Min Buyout risks leaving gold on the table, while listing far above Market Value means your auction will likely expire unsold. For long-term investment, track Market Value trends over 30 days or longer to identify items with consistently rising demand. For flipping (buying low and reselling high within hours), watch Min Buyout volatility patterns -- items that regularly swing between a low floor and a high ceiling are prime flip targets.
Commodity vs. Non-Commodity Items Explained
One of the most important distinctions in the WoW Retail economy is between commodity and non-commodity items. This affects not just how prices are determined, but how you search for items, how competition works, and what strategies are viable for making gold.
How Commodity Markets Work
Commodity items in WoW Retail are sold through a region-wide pool. When you post a stack of Blessing Blossom on the North American Auction House, every player on every NA realm can see and buy that listing. The game automatically matches buyers with the cheapest available commodity listings across all realms. This creates a highly efficient market with tight price spreads -- the difference between the cheapest listing and the next-cheapest is usually just a few copper.
Commodity markets behave more like real-world stock exchanges than traditional MMO auction houses. Prices respond quickly to supply shocks (a popular farming spot gets nerfed, new content releases introduce new material sinks) and follow predictable weekly cycles tied to raid reset schedules. Tuesday and Wednesday in NA (Wednesday and Thursday in EU) typically see the highest commodity prices as raiders stock up on consumables. Weekends often bring lower prices as casual players farm materials.
On Booty Bay Broker, commodity items are displayed with region-wide pricing regardless of which realm you have selected. The realm selector does not affect commodity data because the underlying market is the same for everyone in your region.
How Non-Commodity Markets Work
Non-commodity items -- gear, weapons, pets, mounts, toys, recipes, and other non-stackable or unique items -- are sold on a per-realm (or per-connected-realm-cluster) basis. A rare transmog sword listed on Area 52 is only visible to players on Area 52 and its connected realms. Players on Stormrage, Illidan, or any other server cannot see or buy that listing.
This creates dramatically different market dynamics compared to commodities. Low-population realms may have very few listings for a given item, which means prices can be much higher (due to scarcity) or much lower (due to a single seller dumping stock with no competition). High-population realms tend to have more competitive pricing but also more demand, so items sell faster. When evaluating non-commodity prices on Booty Bay Broker, always make sure you have selected your specific realm in the realm dropdown to see relevant data.
How to Tell If an Item Is a Commodity
In general, stackable crafting materials and trade goods are commodities: herbs, ores, leather, cloth, gems, enchanting materials, pigments, cooking ingredients, elemental reagents, and similar items. Equipment (armor, weapons, trinkets), pets, mounts, toys, recipes, and cosmetic items are non-commodities. When viewing an item on the Retail Auction House page, commodity items will show the same price data regardless of your realm selection, while non-commodity items will update when you switch realms.
Reading Price Charts
The price history charts on Booty Bay Broker are one of the most powerful tools available for understanding market behavior. Each chart plots price data points over time, letting you see trends, cycles, and anomalies that are invisible when looking at a single snapshot. Here is how to read them effectively.
Time Range Selection
You can view charts over four time windows: 24 hours, 7 days, 30 days, or All (the full recorded history for that item). Short time ranges (24h and 7d) are best for identifying immediate trading opportunities -- a sudden price drop you can buy into, or a spike you can sell into. Longer ranges (30d and All) reveal seasonal patterns, expansion-cycle trends, and the item's historical floor and ceiling prices. Start with the 7-day view for everyday trading decisions, then zoom out to 30 days or All when evaluating whether an item is worth a long-term investment.
Understanding Price Lines
The chart displays multiple data series. The Min Buyout line shows the cheapest available listing at each data point -- this tends to be the most jagged line because a single undercut or cancelled listing can move it significantly. The Market Value line is smoother and more stable, representing the weighted median transaction price. When these two lines diverge sharply (Min Buyout drops while Market Value stays flat), it often indicates a temporary buying opportunity. When they converge, the market is in equilibrium.
Volume Patterns
Below the price chart, the volume bar chart shows the quantity of items listed at each data point. Volume is a leading indicator of price movement. A sudden spike in volume without a corresponding price drop usually means increased demand is absorbing the new supply -- bullish for prices. A volume spike accompanied by falling prices signals a dump, where sellers are flooding the market. Consistently declining volume over multiple days suggests the item is falling out of fashion or being replaced by a new alternative, which often precedes a long-term price decline.
Common Chart Patterns to Watch For
Weekly cycles: Many consumable items follow a predictable weekly pattern. Prices rise on raid reset days (Tuesday NA / Wednesday EU) as players buy flasks, food, and potions, then fall over the weekend as casual farmers add supply. Buying materials on Saturday or Sunday and selling on Tuesday or Wednesday can yield consistent margins.
Reset walls: A "wall" appears on the chart as a flat horizontal line where a single player has posted a large quantity at one price, effectively setting a price floor. Walls are common on high-volume commodity items. If the wall is below Market Value, it represents a buying opportunity. If above, it may suppress prices until the stock is consumed.
Patch spikes: New content patches, hotfixes, and balance changes create sudden demand shifts. Items related to new recipes, dungeon requirements, or class buffs can spike dramatically in the hours after a patch goes live. Monitoring patch notes and pre-positioning stock before a patch is one of the most profitable (and risky) trading strategies.
Gradual uptrends: If an item's Market Value has been climbing steadily over two or more weeks with no obvious catalyst, it usually indicates genuine increasing demand -- perhaps from a growing crafting meta or a content phase where the item becomes more relevant. These trends tend to be more sustainable than sudden spikes.
Using the Market Heatmap
The Market Heatmap is a visual dashboard that shows price movement across every tracked item category at a glance. Instead of checking items one by one, the heatmap lets you see the entire market in a single view and quickly zero in on where the action is.
How to Read the Heatmap
Each tile on the heatmap represents an individual item. The size of the tile corresponds to the item's trading volume -- high-volume items get larger tiles, making them easier to spot. The color indicates price change direction and magnitude:
- Green tiles indicate the item's price has increased over the selected time period. Darker green means a larger increase.
- Red tiles indicate the item's price has decreased. Darker red means a larger decrease.
- Gray tiles indicate the price has remained relatively stable.
You can toggle the time window between 24 hours, 3 days, and 7 days to see short-term momentum versus medium-term trends.
Heatmap View Modes
The heatmap offers several view modes to help you find specific opportunities:
- Overview: All items grouped by category. Use this for a general market check.
- By Category: Filter to a single item category (Herbs, Ores, Enchanting, etc.) for focused analysis.
- Best Deals: Highlights items whose current price is significantly below their recent Market Value average. These are the best candidates for buying.
- Fast Movers: Shows items with the largest price changes (up or down) over the selected time period. Use this to catch breaking market shifts early.
Using the Heatmap Strategically
The heatmap is most powerful as a discovery tool. Rather than tracking a fixed watchlist of items, use the heatmap to find opportunities you did not know existed. If the Herbs category is mostly green on the 24-hour view, it may signal that an Alchemy recipe just became popular and herb demand is rising across the board. Click into individual green tiles to check their price history and confirm the trend before investing. Conversely, a sea of red in the Enchanting category might mean a patch just nerfed a popular enchant, and those materials are losing value -- a signal to sell any stock you are holding before prices fall further.
Experienced traders check the heatmap at least once daily, usually after the first data collection cycle following a daily or weekly reset, to see how the market responded to fresh demand.
Professions Calculator Overview
The Professions Calculator on Booty Bay Broker is a tool for evaluating crafting profitability. It takes the current Auction House prices for every material required by a recipe, calculates the total crafting cost, and compares it to the market value of the finished product.
How Crafting Cost Is Calculated
For each recipe, the calculator looks up every required material and multiplies the quantity needed by that material's current Min Buyout price on the Auction House. These individual material costs are summed to produce the total crafting cost. The calculator then compares this total against the Market Value of the recipe's output item. If the output's Market Value exceeds the total material cost, the recipe shows a positive profit margin. If the materials cost more than the result is worth, the recipe is flagged as unprofitable at current prices.
Because material prices change hourly, a recipe that is unprofitable in the morning may become profitable by evening (or vice versa). The Professions Calculator uses the same live price data as the Auction House pages, so the margins you see are based on real, current market conditions.
Tips for Using the Professions Calculator
Check multiple realms: Material prices vary by realm for non-commodity inputs. A recipe might be profitable on a high-supply realm but unprofitable on a low-supply one. Switch realms in the calculator to compare.
Account for posting fees: The Auction House charges a deposit when you list items and takes a 5% cut on successful sales. These fees eat into your margins, so recipes showing less than 10% profit may not be worth the effort after fees.
Watch for gathering shortcuts: If you can farm some of the materials yourself instead of buying them, your effective crafting cost drops significantly. The calculator assumes you buy everything at market price, so self-gathered materials represent pure upside on top of the displayed margin.
Track margin trends: Check a recipe's margins over several days. If a recipe consistently shows positive margins, it is a reliable gold maker. If margins swing wildly between profitable and unprofitable, the item's market may be too unstable for consistent crafting profits.
WoW Classic Auction House
How the Classic Auction House Differs from Retail
The World of Warcraft Classic auction house operates very differently from its Retail counterpart. In Classic versions, each faction maintains its own separate auction house -- Alliance players post and buy from Alliance auctioneers in cities like Stormwind and Ironforge, while Horde players use auctioneers in Orgrimmar and Thunder Bluff. This faction split creates two distinct economies on every server, with different supply levels, pricing patterns, and opportunities for each side. Neutral auction houses exist in locations like Gadgetzan and Booty Bay, but they charge a significantly higher deposit and cut, making them useful primarily for cross-faction transfers rather than everyday trading.
Retail WoW introduced a unified, region-wide commodity system where trade goods like herbs, ore, and cloth share a single price pool across all servers in a region. Classic has no such system. Every item on every Classic realm is priced independently based on local supply and demand. This means a stack of Thorium Ore might sell for vastly different prices on a high-population server compared to a quieter one. Tracking these per-realm differences is exactly what Booty Bay Broker is built to do.
What Data We Track and How
For Classic WoW versions (MoP Classic and TBC Anniversary), Blizzard does not provide a public Auction House API the way it does for Retail. Instead, Booty Bay Broker sources pricing data from the TradeSkillMaster (TSM) API, one of the most trusted data providers in the WoW economy community. TSM collects auction house scans from thousands of players running the TSM desktop application, aggregating listing data into reliable market statistics. The data includes minimum buyout prices, market value estimates (a weighted median that filters outlier listings), average buyout prices, and the total quantity of each item currently listed. We store full price history so you can analyze trends over days, weeks, and months -- not just a single snapshot in time.
Connected Realms in WoW Classic
Blizzard uses connected realms to merge the populations (and auction houses) of lower-population servers. When two or more realms are connected, they share a single auction house, guild system, and trade channel. This means players on connected realms see the same listings and compete in the same market. Booty Bay Broker automatically groups connected realms together so you always see the correct, combined market data for your server cluster. If your realm has been connected to others, you will find it listed under its primary realm name in our realm selector.
Classic vs. Retail: Key Differences
While both Classic and Retail share the same core auction house concept -- players listing items for other players to buy -- the two versions differ in ways that fundamentally change how you approach trading. Understanding these differences is essential if you play both versions or are transitioning from one to the other.
Market Scope
In Retail, commodity items (herbs, ores, cloth, etc.) are traded on a region-wide market. All NA servers share one commodity pool, and all EU servers share another. This means commodity prices are the same on Area 52 as they are on Moon Guard. Non-commodity items remain per-realm.
In Classic, every single item is traded on a per-realm, per-faction basis. There are no region-wide markets. A stack of Peacebloom on Alliance Mankrik-US has a completely independent price from Peacebloom on Horde Mankrik-US, let alone a different server entirely. This creates far more price variation and arbitrage opportunities, but also means less liquidity per market.
Faction-Split Economies
Retail WoW merged the Alliance and Horde auction houses years ago. Both factions share a single auction house on every realm. In Classic, the faction split remains intact. Alliance and Horde each have their own separate auction house with different listings, prices, and supply levels. On Booty Bay Broker, you can toggle between Alliance and Horde views for any Classic realm to see faction-specific pricing.
Data Sources
Retail data comes directly from the official Blizzard Battle.net Game Data API, which provides near-real-time auction house snapshots updated hourly. Classic data comes from the TradeSkillMaster (TSM) API, which aggregates scan data uploaded by TSM addon users. TSM data is highly reliable on active servers but may have slightly longer delays than the official Blizzard API. On very low-population Classic realms with few TSM users, data freshness can vary.
Trading Strategy Differences
Retail trading favors volume-based strategies: buy large quantities of underpriced commodities and relist for small per-unit margins, relying on high turnover. The region-wide market ensures sufficient liquidity for this approach. Classic trading rewards patience and realm knowledge: because markets are smaller and less liquid, you can corner a niche market or find items listed far below their true value. However, items may take longer to sell, and overinvesting in a single realm's market carries more risk since you cannot easily move your inventory to a different server.
Beginner Gold-Making Strategies
If you are new to Auction House trading, these foundational strategies will help you start building gold without requiring large upfront capital or deep market knowledge.
Basic Flipping
Flipping is the simplest form of AH trading: buy an item at a low price and relist it at a higher price. The key is finding items that are priced below their Market Value. On Booty Bay Broker, compare an item's current Min Buyout against its 7-day Market Value. If Min Buyout is 20% or more below Market Value, the item is potentially underpriced. Buy it, relist it near Market Value, and pocket the difference minus the 5% AH cut. Start with high-volume commodity items where demand ensures your relisted auction will actually sell within 12-24 hours.
Market Resets
A market reset involves buying out all (or most) listings of an item and relisting the entire stock at a higher price. This is a higher-risk, higher-reward strategy that works best on items with limited supply and consistent demand. Before attempting a reset, check the item's price history on Booty Bay Broker to confirm that the price you plan to reset to has actually been sustained in the past. If the item's all-time chart shows it has never held above a certain price for more than a day, your reset is likely to fail as new supply enters the market.
Diversification
Never put all your gold into a single item or category. Spread your investments across multiple item types -- some commodities, some equipment, some consumables. If one market crashes (perhaps due to a hotfix nerfing a recipe), your other investments cushion the loss. Use the Market Heatmap to identify multiple opportunities across different categories rather than focusing on a single niche.
Timing Your Trades
The WoW economy follows predictable weekly rhythms. Prices for raid consumables (flasks, food, potions, weapon enhancements) peak on raid reset days -- Tuesday in North America, Wednesday in Europe. Crafting materials are cheapest on weekends when casual players farm and list in bulk. Plan your buying for weekends and your selling for early in the week to maximize margins. Check the 7-day price history chart on Booty Bay Broker to confirm whether an item follows this pattern before committing to a timing strategy.
Gold-Making in TBC Anniversary
TBC Anniversary offers some of the most rewarding gold-making opportunities in Classic WoW. Outland materials like Primal Fire, Primal Air, and Primal Nether command premium prices because they are required for endgame crafting recipes. Herbalists can profit handsomely from farming Terocone, Nightmare Vine, and Fel Lotus, all of which are consumed in large quantities by raiders for flasks and elixirs. Jewelcrafting is a major gold driver in TBC -- rare gem cuts from Heroic dungeons and reputation vendors sell consistently well. Keep an eye on our market heatmap for sudden price spikes around weekly raid resets, when demand for consumables peaks.
The TBC economy revolves heavily around daily cooldowns. Tailoring cooldowns (Shadowcloth, Spellcloth, Primal Mooncloth) and Alchemy transmutes (Primal Might, various gems) are time-gated, creating consistent demand for the materials they consume. Tracking the prices of cooldown inputs versus outputs on Booty Bay Broker helps you decide whether to sell raw materials or use your daily cooldown for a higher-margin crafted result.
Key TBC Professions for Gold
Alchemy is arguably the most consistent gold maker in TBC. Daily transmutes of Primal Might (combining all five Primals) or gem transmutes (turning common gems into rare ones) provide a guaranteed daily income with no farming required. The Transmutation Master specialization gives a chance to proc extra items, increasing your average return.
Enchanting thrives on the steady demand for weapon and armor enchants as players gear up through Heroic dungeons and raids. High-end enchants like Mongoose, Executioner, and Sunfire require expensive materials that you can source cheaply by tracking price dips on Booty Bay Broker.
Mining and Herbalism are the most accessible gold-making professions since they require only time investment, not recipe knowledge. Outland zones like Nagrand (for Adamantite and herbs) and Shadowmoon Valley (for Khorium and Black Lotus) are prime farming routes. Check realm-specific prices on Booty Bay Broker before choosing your route, as material values vary significantly between servers.
Gold-Making in MoP Classic
Mists of Pandaria Classic features a mature and diverse economy. The Auction House sees heavy traffic in crafting materials like Ghost Iron Ore, Trillium Ore, and Spirit of Harmony. Cooking ingredients from the Valley of the Four Winds -- particularly vegetables for stat-food recipes -- trade in high volume as raiders stock up before progression nights. The Black Market Auction House adds another dimension to the MoP economy, creating demand for rare mounts and transmog gear that trickles into regular AH activity. Watch our market heatmap around weekly resets and patch content releases for the best flipping opportunities, and use the price history charts to identify items that reliably cycle between low and high prices.
MoP's profession system introduced a high degree of material interdependency. Blacksmiths, Leatherworkers, and Tailors all need Living Steel (crafted by Alchemists) for their best recipes, while Jewelcrafters depend on Ghost Iron Ore for prospecting and Engineers need the same ore for various crafts. This interconnection means a price change in one material category ripples across multiple professions. Use the Professions Calculator to track these cross-profession margins and identify the most profitable links in the crafting chain.
Classic Auction House FAQ
How does Classic AH data differ from Retail?
Retail WoW uses the official Blizzard Auction House API, which provides near-real-time commodity pricing on a region-wide basis. Classic versions do not have a functioning Blizzard AH API -- Blizzard's Classic endpoints have returned errors since late 2024. Instead, Classic data comes from the TradeSkillMaster (TSM) API, which aggregates auction house scans uploaded by players. This means Classic data may have a slight delay compared to Retail, but it is still updated multiple times per day and reflects actual in-game listings accurately.
What are connected realms in WoW Classic?
Connected realms are two or more servers that Blizzard has linked together to create a larger combined population. Players on connected realms share the same auction house, can join the same guilds, and trade with each other as if they were on a single server. Booty Bay Broker automatically detects connected realm groups and presents unified pricing data for the entire cluster. You do not need to search for each connected realm individually -- simply select your primary realm and you will see the full combined market.
How often is Classic AH data updated?
Classic auction house data is refreshed multiple times per day through the TSM API. The exact update frequency depends on how many TSM users are actively scanning on each realm -- high-population servers tend to receive more frequent updates. On most active realms, you can expect price data to be no more than a few hours old. Booty Bay Broker records every data point we receive, building a comprehensive price history that lets you see trends over 24 hours, 7 days, 30 days, or the full tracked period.
What is TSM and how is the data collected?
TradeSkillMaster (TSM) is the most widely-used auction house addon for World of Warcraft. Players who install the TSM desktop application automatically upload auction house scan data from their game sessions. The TSM API aggregates these scans across all contributors on each realm, producing reliable statistics including minimum buyout, market value (a weighted median), historical prices, and listing quantities. Booty Bay Broker queries the TSM API on a scheduled basis to keep our database current, then stores the full price history for long-term analysis and charting.
Which Classic versions are supported?
Booty Bay Broker currently tracks auction house prices for MoP Classic (Mists of Pandaria Classic) and TBC Anniversary (The Burning Crusade Classic). Each version has its own dedicated page with realm selection, faction filtering, category browsing, and full price history. You can switch between versions using the navigation links at the top of the page or the cross-version links at the bottom. Retail WoW (currently the Midnight expansion) is also fully supported on a separate page with its own commodity pricing system.
Why are Alliance and Horde prices different in Classic?
In Classic WoW, each faction operates its own independent auction house. Alliance players can only see and buy items listed by other Alliance players (at faction auctioneers), and the same applies to Horde. Because each faction has different player demographics, farming habits, class distributions, and population sizes on any given server, supply and demand differ between the two sides. A material farmed primarily by Druids (a class popular with Alliance) may be cheaper on the Alliance AH than on the Horde AH for that same server. Booty Bay Broker lets you toggle between factions to compare these price differences.
Auction House Glossary
Quick reference for common terms used throughout the WoW economy and on Booty Bay Broker.
A - F
AH -- Auction House, the in-game marketplace where players list items for sale.
Bid -- The starting price of an auction. Buyers can bid on items and win them when the auction expires if no one bids higher. In Retail WoW, most players use Buyout instead.
Buyout -- The fixed price at which a buyer can instantly purchase an item without waiting for the auction to expire.
Commodity -- A stackable trade good (herb, ore, cloth, etc.) that is sold on a region-wide market in Retail WoW. See the Commodity vs. Non-Commodity section above.
Connected Realm -- Two or more servers merged by Blizzard that share the same AH, guilds, and trade channels.
Deposit -- A fee paid when listing an item on the AH. If the item sells, the deposit is refunded. If the auction expires unsold, the deposit is lost.
Flip -- Buying an underpriced item and relisting it at a higher price for profit.
G - M
Gold Cap -- The maximum amount of gold a single character can hold (currently 9,999,999 gold, 99 silver, 99 copper in Retail).
Listing Quantity -- The total number of individual units of an item currently posted on the AH.
Market Value -- A weighted median price representing the typical transaction price for an item. More stable than Average Buyout because it filters outliers.
Min Buyout -- The lowest buyout price among all active listings for an item.
Median Buyout -- The middle value when all listing prices are sorted from lowest to highest.
N - Z
Non-Commodity -- An item sold on a per-realm basis rather than region-wide. Includes gear, pets, mounts, toys, and recipes.
Region -- A geographic grouping of servers. Booty Bay Broker tracks NA (North America) and EU (Europe) regions.
Reset -- Buying out all listings of an item and relisting at a higher price to control the market.
Snipe -- Buying an item that was listed far below its market value before other buyers notice it.
