If you use the TradeSkillMaster Application from tradeskillmaster.com, you have access to WoWuction.com's daily market-price updates based on 24/7 hourly scans, so you don't have to worry about day-versus-night bias when your computer's off.
But on high-traffic auction houses, even WoWuction doesn't tell you the whole story. Here's why you need to use more than one price source, and take advantage of Auctioneer Appraiser's ability to combine them into one estimate (called "ensemble regression").
- Prices change from second to second when your competitors are using TSM, so even one scan per hour isn't always enough.
- Different sites disagree on their choice of aggregation algo, with different strengths and weaknesses. In my spreadsheet testing, TheUndermineJournal and WoWuction differed by 19% in their 14-day median Ghost Iron Ore prices on a high-population US PvP realm!
- Auction-scan addons don't know what auctions will and won't actually sell. But with BeanCounter, you do, and Auc-Stat-Sales helps you take advantage of that.
To get smarter price estimates, enable this module alongside other Auc-Stat modules such as Auc-Sat-WoWuction, Auc-Stat-TheUndermineJournal and/or Auc-Stat-Sales. Turn on hourly AuctionDB scans in the TradeSkillMaster app. Choose "Auctioneer - Market Value" as your source for mat costs, crafting costs, thresholds for non-crafted items (and any crafted items you're willing to sell at a loss), and fallback prices. (Don't use "Auctioneer - Appraiser" for any TSM purpose except Quick Post, and even then with caution, since it includes undercuts and may be using an out-of-date scan.)
