How this chart is drawn
One value a day. The 1Y and MAX views show one point a week.
TCGplayer's own chart is drawn per condition, so it can differ from this one.
Compared with its group
A gap in percentage points: this card's change minus the typical change of modern Pokémon cards (ungraded, English). Each window compares the latest price to the most recent one at least 30 or 90 days older, so the exact span differs from card to card. On ~30d: this card +3.1%, the typical card +1.3%. On ~90d: this card -6.9%, the typical card +6.3%. The group spans every price level, so it is an era-and-format population, not a set of comparable cards.

Day-over-day moves in the tracked record, largest first. Moves smaller than $0.25 are left out. Each price is TCGplayer's market price, one published value per day for this printing; a move here is that value changing between two days, which this record cannot tell apart from a single sale.
