cx
the published fix of the century-index — ticker CX. one CX is the basket that cost one dollar on the base date, so the level is a price: $1.42 on 2026-09-29, against $1 on 2022-01-07. the protocol page defines the instrument; this subgraph carries what it actually read.

- cx history — the monthly level since the base date, the quantities, the sources
- century-index — the protocol: basket, collar, floor, contract theses
how the fix is built
- pull each leg from its public source
- carry every fix onto a dense daily calendar — a closed market holds its last print
- average each leg over the trailing 365 days
- hold the quantities fixed from the base date and sum them at today's averages
the arithmetic is integer fixed-point end to end, so the same day's data yields the same level on any machine — the index is reproducible by anyone holding the sources, which is the whole point of an obligation nobody has to be trusted about.

shares drift as prices move; the quantities behind them never do. measured in itself the index is constant, so the obligation carries no numéraire.
