Frequently Asked Questions

How are market movers calculated?
Cards are ranked by percentage price change over the selected time window (24 hours, 7 days, or 30 days) using daily TCGPlayer market price snapshots. Only cards with a minimum price filter you set (default $1) are included so low-value noise is excluded.
What time window does this cover?
The day window compares yesterday's closing price to today's. The week window compares prices from 7 days ago to today. The month window uses a 30-day lookback. All times use UTC and prices update once daily after the TCGPlayer data refresh.
Are Foil and Normal cards tracked separately?
Yes. Foil and Normal variants have separate TCGPlayer listings and separate price histories. A card can appear twice in the movers list if both its Normal and Foil variants moved significantly.
Where does the price data come from?
Prices come from TCGPlayer via the TCGCSV API, which provides a free daily cache of TCGPlayer market data. Prices refresh daily around 4 PM EST. WealthFamePower is not affiliated with TCGPlayer.
