IN PLAIN ENGLISH
Shows how far each card you hold has moved in the market over the last 7 or 30 days, from the biggest rise to the biggest fall. It's the Gainers & Losers widget with Collectible cards: price move picked as its data, and it needs no paid value.
WHY IT HELPS
Shows which cards in the collection are heating up or cooling off right now, without waiting for the longer value-over-time chart to bend.
HOW IT'S CALCULATED
For each card: Move = copies × (today's market price for its printing − its price at the start of the window), converted at today's exchange rate; % = (price today − price then) ÷ price then × 100. Pick 7 or 30 days and whether to rank by the amount or by the percentage. A card bought inside the window is measured from its buy date; one with no price that far back, no recent price, or no price for its printing is counted in the note underneath rather than guessed. Each bar is drawn to scale against the largest move in the list, rises to the right of zero and falls to the left.
