Per-venue basis for one crypto perpetual — mark versus index price, basis_bps = (mark−index)/index×10000, and contango/backwardation structure, across tracked CEX and DEX venues. Every venue has an index except Crypto.com, Variational and dYdX; dYdX publishes one oracle price, which is its mark. `venues_without_index` names the ones missing. Each venue also carries liquidity_state (live/dead/unknown), and a market with no trading is flagged unreliable however clean its basis looks.Overview
