Platform status
Data lag: 0 h · uptime is measured from outside our servers, not by the platform itself.
Uptime history appears here as soon as the external watchdog reports its first probes.

Receipts. Every recorded day gets a public fingerprint: SHA-256 over the sorted list of its streams, row counts and the hashes of the stored daily files. Save today's receipts (receipts.json) and compare later — a final day's fingerprint never changes, so nobody, including us, can quietly rewrite history.
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.
USD-M futures validation
These are separate checks for futures records. Spot Q is not a futures quality score. Gaps remain reported after collection resumes.

Incidents
08.11 10:12 8 November: collector maintenance completed
resolved
Collectors were restarted one at a time at 10:12–10:14 UTC. All 29 missing spot aggregate-trade IDs were recovered. Four BTC, nine SOL and one ETH raw futures trade events could not be recovered and remain declared gaps. The books for all three assets synchronized after restart. Automatic daily processing, backup processing and POD evaluation subsequently completed successfully; temporary-file cleanup also ran automatically. This resolves the operational maintenance, while historical missing futures events remain documented.
07.11 23:59 7 November: recorded collection gaps remain flagged
open
Spot collection has two coverage gaps per asset, about 102–103 seconds in total. The daily Spot Q index is 96. Final spot trade-tape comparison against the exchange reports no missing, extra or value-mismatched aggregate trades for BTC/USDT, ETH/USDT and SOL/USDT. Recovering the tape does not recreate missing historical L2 updates. Futures has two coverage gaps per asset, about 36 seconds in total and about 25 seconds for the longest interval. Sequence checks report zero breaks, and 12 event-exact bid/ask probes match per asset. Full futures replay and exchange-archive trade parity have not been checked. Current collection has resumed; the historical gaps remain in the quality record.
23.10 23:59 Incomplete data collection on 2026-10-23
resolved
Collection on 2026-10-23 was incomplete. Quality index Q = 100 (healthy is 90 and above). 0.00% of the day was lost, holes longer than 5 seconds: 0, the longest one 0m. Records in the raw stream: 3744417. The order book for this day does NOT rebuild reliably on BTC/USDT: only 99.8541% of bid/ask probes matched the independently recorded top of book, and we are not hiding it. The day is left as it is — backfilling after the fact would mean the numbers on the storefront change after the sale. The day is flagged in the data map (has_gaps), and every backtest report that touches it carries a «day with collection gaps» badge.
18.10 23:59 Incomplete data collection on 2026-10-18

Records in the raw stream: 3288247. Delivery latency tail was high on BTC/USDT: p99 = 4971.0 ms (penalty 30.0 of 30). Rows are complete; timestamps are exchange time, so the data itself is unaffected — only how late we received it. 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. The day is flagged in the data map (has_gaps), and every backtest report that touches it carries a «day with collection gaps» badge.
