Trading card screener

It filters every priced card we track by the things that matter for trading: price range, how much it moved over 1, 7, 30 or 365 days, how far it sits from its own one-year high and low, and the gap between market price and the cheapest listing. Every filter is in the address bar, so any screen you build can be bookmarked or shared.

Spread is the gap between the market price — what near-mint copies actually sold for — and the cheapest copy listed right now. A wide spread means either an opportunity or a thin market where one battered copy sets the floor. Check the listing count before treating it as a bargain.

Where today's price sits inside the card's own one-year range: 0% is the year low, 100% the year high. It says nothing about whether a card is cheap against the market, only whether it is cheap against its own history.

Because a two-cent card that moves to four cents is a 100% gainer and would fill every list. The presets set a floor so the results are cards you could actually trade.
