Prices are daily averages weighted by the number of keys. Dates without completed trades are omitted.
How the history is calculated
Each daily price is weighted by the number of keys in completed tf2cart trades. Cancelled, failed, pending, admin-only, and unpaid orders are excluded. Dates without completed trades are omitted.
How to interpret it
Buy is what customers paid tf2cart per key. Sell is what tf2cart credited customers per key. Historical prices describe completed trades and do not promise a future quote.
Update methodology
The public endpoint reads the previous 90 days and caches the anonymized aggregate for five minutes. The page keeps the last build-time snapshot if a refresh fails.
