Slabline™
Graded-card protection score
Slabline™The Digimon index is flat 0.05% over this period, -0.01% in the last 7 days against -0.05% over 30. It sits 0.05% below the period high (99 on Sep 12) and 0.00% above the period low (Sep 26).
Range-bound: no clear direction over this period — moves in the underlying rookie and grade baskets matter more than the index.
Arithmetic over the index level series (7/30-day change, daily volatility, drawdown, distance from the period high and low). Not investment advice.
Value-weighted index, base 100 at the window start: the sum of the basket's observed values against the prior day's, chained daily, each card's move capped so one outlier can't dominate. Values come from real comparable sales resolved on Slabline card pages. The window deepens automatically as history accumulates. Not investment advice.
