Q is the day quality index: it is computed from the share of collection time lost and from sequence gaps — measured, not declared. Rows below 70 are highlighted. Book rebuild: the order book is rebuilt from our l2 diffs and compared with the independently recorded top of book. Tape vs exchange: every trade_id of the day is compared with Binance's own public archive (data.binance.vision) — "0 missing" means the tape is identical to the exchange's record, row for row.
Incidents
18.10 23:59 Incomplete data collection on 2026-10-18
open
Collection on 2026-10-18 was incomplete. Quality index Q = 40 (healthy is 90 and above). 8.50% of the day was lost, holes longer than 5 seconds: 7, the longest one 1h 52m. Records in the raw stream: 3288247. Delivery latency tail was high on BTC/USDT: p99 = 4971.0 ms (penalty 30.0 of 30).

The order book for this day rebuilds correctly — 100.0% of bid/ask probes matched the independently recorded top of book. The day is left as it is — backfilling after the fact would mean the numbers on the storefront change after the sale.
