Market count reflects the Mobula perp pairs catalog at query time. Only mainnet markets are counted (testnets excluded). Asset class tags (forex, stocks, indices, commodities) are assigned by Mobula's editorial taxonomy and updated when new pairs are listed. Venues not in the Mobula catalog (Hyperliquid, GMX, dYdX, Ostium, Vertex, Paradex, Aster) are monitored separately: their catalogs are crypto-only or verified crypto-only by native API.

Editorially curated pairs (like this one) may publish early when search demand is high and data is accruing; panels with fewer than 100 samples are shown as provisional. The full pair ledger is versioned in the public repo.
