Indexes

Orrery Indexes

Each index is a 0-100 composite of average 24h move, total 24h volume, and resolution pressure across the markets in a category. Higher means the category is louder right now. Public Polymarket data, refreshed every 30 minutes, never trade calls.

Formula

transparent
index =
  0.5 × normalised average |Δ24h|        (how much things moved)
+ 0.3 × normalised total 24h volume       (how much attention)
+ 0.2 × resolution-pressure component     (concentration of <72h)

Each component is normalised against a category-specific ceiling (hand-tuned from observed historical maxima) so scores are bounded and comparable across indexes. No persistent store yet — once Orrery has signal-firing history we'll add a day-over-day delta and an archive at /indexes/[slug]/[date].
