HKJC Odds Movements — Full Archive
HKJC odds movement archive since December 2021, continuously extended (one-off)
Complete archive of HKJC odds movements, from December 2021 to the latest meeting, at last-sync (hourly) freshness. One row per odds movement: each row is a change in a pool's odds, timestamped with the Hong Kong Jockey Club's own published update time (snapshot_timestamp, UTC); repeated unchanged states are not stored — interpolate flat between rows. observed_at records when our collector first saw each state, and timestamp_source marks the small residue of rows (certain exotic matrices) where HKJC publishes no update time and the collection clock is used instead. How finely movements are resolved depends on the collection era: polling ran about every 5 minutes for most of Dec 2021 to mid-2023 and late 2024 through 2025, about every minute mid-2023 to Q3 2024 and since May 2026 — so consecutive moves inside one polling interval collapse into the latest one, and sub-minute resolution is only available from June 2026 onward. WIN and Place pools from December 2021; exotic pools (Forecast, First Four, Trio) from February 2024; remaining pools (Double, Quinella, QPL, and others) from October 2024. Your download is the archive as of your purchase date — a dated artifact; re-downloads serve the same vintage. One-off purchase; for same-day odds during race meetings (refreshed hourly), see Racing Pass Enterprise.
