How this chart is drawn
One value a day. Where a short view would draw too many points it thins to one point every few days and says so in its caption; 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. This page holds one value per printing and does not say which condition it is for.
Vs its era
A gap in percentage points: this card's change minus the typical change of recent Yu-Gi-Oh! 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. Over about 30 days neither this card nor the typical card in this group moved. On ~90d: this card -35.4%, the typical card -0.6%. The group spans every price level, so this compares the card with its era's typical move, not with similar 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 value per day for this printing, built from recent sales; a move here is that value changing from one day to the next. How many sales sat behind a move is not in this record.
