We're excited to announce that raw PCAP files from Blue Ocean ATS (BOATS) are now available on Databento, offering coverage of after-hours US equities trading.

Blue Ocean ATS (BOATS) is recognized as a leading marketplace for overnight trading, operating an overnight session, the Blue Ocean Session, from 8:00 pm to 4:00 am ET, Sunday through Thursday. This window enables trading on US equities while many other exchanges and venues are closed, and is especially convenient for anyone operating in the Asia-Pacific or other international time zones.

Our new PCAP offering provides lossless market data captured directly from BOATS' MEMOIR Depth feed.

Key features:

  • Direct capture enabling replay of every book event, with higher granularity than MBO data.
  • Nanosecond PTP timestamps synchronized to a GPS clock with sub-microsecond accuracy
  • Lossless market data in raw wire format before any normalization
  • Same-day delivery with flexible customization options

We're also working on normalized BOATS data, which will be integrated into our US Equities offering when it's ready.

Blue Ocean ATS PCAPs are available starting at $500 per month. Visit our PCAPs page for more information or contact us to discuss your specific data requirements for after-hours trading analysis.
