How the indexes work
What is in the The Achroma Collection index?
ShowHide
Every skin the catalogue files under the The Achroma Collection that has Skinport volume, in every wear and variant a market quotes. 108 names qualify today and 108 of them have Steam sold history, so the line is drawn from those 108; the rest join as their histories arrive.
How do I read the number?
ShowHide
A point above 100 means the typical member sells for more than it did on its own first recorded day; below 100, less. It is a level, not a price, and not a forecast. The 24h, 7d and 30d figures compare the last published day with the exact day that many days before it, so they can read "no read" on a series with gaps. Compare it with every other index or read the market report for the composite, the fear and greed read and the movers.
