Prophecy

PMVIX methodology

How a reading is produced, in eight stages, from venue data to a published number.

Publication
Current version
1.0.4
Recompute cadence
Every 5 minutes
Chained history
1.0.4, 1.0.3, 1.0.2, 1.0.1

Published history only chains versions whose headline meaning is compatible, which is why the chart stays continuous across a version change. Where a version boundary falls inside a chart window it is drawn on the series.

1

Collect

Prices and order books are pulled from each venue on a fixed schedule and validated before anything is stored.

3

Screen

Eligibility gates exclude anything stale, too thin, too wide, halted, or too near or far from resolution.

4

Price

For each eligible outcome a depth-weighted price is taken from the book rather than the last trade, then carried into log-odds.

5

Reconcile

Prices for the same canonical payoff become one consensus, and the disagreement between venues is measured rather than averaged away.

6

Relate

A bounded 30-day hourly panel estimates how each event moves and how events move together, so one theme cannot count twice.

7

Aggregate

Concentration caps are applied and the resulting portfolio variance is annualized onto the published scale.

8

Publish

The series is smoothed for readability and an uncertainty band is drawn by resampling the eligible events.

Each stage carries its own parameters and evidence on the PMVIX board, where the live numbers for the selected lane sit beside the step that produced them.
