Its not a PCAP file. Its NASDAQ's ITCH data from 15th May 2026. This is the link: [https://emi.nasdaq.com/ITCH/Nasdaq%20ITCH/](https://emi.nasdaq.com/ITCH/Nasdaq%20ITCH/), the filename is "itch50\_05\_15.gz". Its about 13GB and 30GB when uncompressed.
The repository is split into two parts. The first part is the exchange simulator, it outputs ITCH messages via MoldUDP64 and receives OUCH messages. It also runs a basic matching engine behind the quoted symbols. I use a ConnectX-4 Lx which is wired into the Solarflare NIC using SFP28 DAC(25GbE) cables.

The second part of the repository is the feed handler which is where the tick-to-trade path lives. This is what runs on the Solarflare NIC. I tried to emulate HFT market making as much as possible.
