Open contracts have no settlement name yet, so each is described by its parsed symbol: market type, line, selection code, period and maturity. Selection codes (e.g. ATLB000) are the exchange's opaque identifiers.

Open interest by time to maturity

  1. 10–1 days1 contracts88
  2. 28–30 days597 contracts1,562,296

Maturity is the listed expiry, which for game markets sits after the game and for early-settled markets overstates time to resolution.
