CardTrader raw market
CardTrader supplies active raw-card listings used for English and supported Japanese market observations. Near Mint eligibility, language and minimum offer depth are checked before a close can enter daily history. Active asks describe visible supply, not a completed transaction.
Verified graded sales
Completed graded-card records are discovered from eBay and retained only after card identity, language, grade and sale evidence pass the matching rules. PSA, BGS and CGC records remain separated by grade in the public history.
Catalog and publisher records
Official game catalogs and mapped provider records establish card identity, set, code, printing and imagery. Bandai sources support One Piece and Dragon Ball announcements; Riot Games sources support Riftbound announcements.
Currency and storage
EUR and USD displays use the platform exchange-rate service while the source currency remains preserved. PostgreSQL stores accepted daily observations, graded evidence and operational provenance used by the public research views.
Missing data
NO DATA means the required evidence is not currently available. TCGMarketWatch does not invent a value from a different language, printing, condition or unverified listing.
