## In one sentence

Each index is the geometric average of ten members' prices relative to where they started, so 112 means the basket is 12% above its starting point.

As of 2026-10-22, the Atrium XBT Runes index stood at 78.3, from 10 members. As of 2026-10-22, the Atrium XBT Ordinals index stood at 97.6, from 10 members.

## Ordinals

- **Members:** the ten collections our own node saw sell most by value over 30 days, each with at least 10 clean sales in that time.
- **Price:** each collection's daily median sale price, from our own sales, with wash-flagged sales and outliers left out (see [collections](/methodology/collections)). A day priced more than 5 times away from the collection's own typical price is treated as bad data and skipped; quiet days carry the last price.
- **History:** rebuilt from our sales every run, like the Runes index. Days follow the viewer's own calendar. (Before 12 October 2026 this index was built from an outside marketplace's floor prices.)

## Runes

- **Members:** the ten runes our own node saw trade most by value over 30 days, with wash-flagged trades left out (see [wash-trade flags](/methodology/wash-trades)).
- **Liquidity rule:** a member must have traded at least 30 times, on at least 60% of the days.
- **Price:** each rune's daily median price per token, from our own sales (see [rune sales](/methodology/rune-sales)). A day priced more than 5 times away from the rune's own typical price is treated as bad data and skipped.
- **History:** rebuilt from our trade history every run. Days follow the viewer's own calendar.

## Why equal-weighted and geometric

Equal weight means a small collection counts as much as a big one, so the index measures the breadth of the market rather than one giant. The geometric average keeps one member's wild day from dragging the whole number.

## Known limits

- Things that faded are not in either basket, which flatters the past a little (survivorship bias).
- Both baskets are **today's** top ten, tracked back.
- A collection's daily median moves with which items happened to sell that day, so a thin day can swing it.
- Both indexes use only our own node.
