go-finproto is a collection of finance-related protocols implemented in Golang.
Protocols are contained within top level packages in this repo, and examples of each protocol can be found in the cmd directory.
The itch directory contains a parser for Nasdaq's ITCH 5.0 protocol.
The soupbintcp directory contains a server and client implementation of Nasdaq's SoupBinTCP 4.1 protocol.
Have a suggestion for a protocol to be implemented? Open an issue and I'll take a look. If I think it will be fun, I'll implement it. I also welcome implementations from others if you create a pull request.
