Data coverage

The listed and collected counts refer to venue listings, including listings shared across venues. Expand a row for layer detail.

How to read this: The percentage is the share of eligible retrospective API reads that return a current value at selected past instants. The colored dot and rule follow that percentage; a separate outlined square means at least one collector gap was logged, possibly for one listing for seconds. DEBYKO reads collected ticker, mark, funding, open interest and 24 h stats at four UTC instants per day. Short interruptions between instants may be missed.

Reading observed freshness…

Each cell covers one UTC day, or up to seven days in the 90-day view. Percentages aggregate check counts, not venue averages, for listings still collected when the result is computed. Not published, intentionally off and out-of-retention checks are excluded; the latter are disclosed in the details. Historical eligibility uses the collection policy in force when DEBYKO computes the result, because earlier policy settings are not versioned; a policy change can therefore affect a past day's denominator. Initial backfill covers up to 30 days; older cells fill in as daily measurements accrue. These observations are neither continuous uptime nor proof that every exchange message was stored. Gap markers count logged events, not missing snapshots or minutes. Select a cell for its sample count and breakdown.
