Methodology
- Sample: every item in the public CS2 inventories tracked on CSGAIN, priced on Buff163 in USD (via PriceEmpire).
- Daily value: the average of each day's price snapshots (UTC days).
- Reference days: one per week, starting on the first day with data. Every daily value is compared directly with the latest reference day, so daily noise can't pile up.
- Item change: the median change across all inventories that hold the item. Moves above 60% within one inventory are excluded, because they come from buying or selling, not from price changes.
- Index change: the 10%-trimmed mean of all item changes (equal-weighted, so a single expensive knife can't move the index on its own).
- Index level: only the weekly reference days are chain-linked, starting from a base of 100. Days without data are skipped, not estimated.
- Updates: hourly. The current day is provisional until it closes.
- Movers: skins held in at least 2 tracked inventories with a Buff163 price of at least $1; weekly moves above 60% within one inventory are treated as inventory changes and excluded.
The index reflects the skins CSGAIN users actually hold, not every item on the market. It's a market barometer, not financial advice.
