For each WoW realm/faction an average daily total Market Value of last 14 days is found.
Market Volume uses various methods to exclude extreme and unreliable auction house posts, resulting in a stable metric for economic activity.
ESBP is a price of chosen 'Essentials Shopping Basket' for the realm. ESBP Index is ratio of basket price and median among all region auction houses.
Higher ESBP and Index means that realm is more expensive and that gold should be valued less on it.

Tables use 14-day item AH price stats to choose competing items. Popular items are included (seen on most WoW realms) and chosen among those are market intensive items (those constituting top 15% by total auction house posted value). For items chosen this way, linear regression is calculated for the last 14 days and used as price trend.

Tables use yesterday's item AH price stats to choose competing items. Popular items are included (seen on most WoW realms) and chosen among those are market intensive items (those constituting top 15% by total auction house posted value). For items chosen this way, linear regression is calculated for the last 14 days and used as price trend.

For each WoW profession, a sum of posted popular products is calculated. An average of this sum across all realms/factions and across last 14 days is found.
Final value represents a daily average volume of popular profession products on a realm.
This value is compared to average total Market Volume of realms in the same period to determine each profession's average market share.
