Using Rails to communicate with the New York Stock Exchange

Start a watch party

Martin Jaime Morón

This is a timely talk because of what happened with Gamestop/Robinhood, introducing a case of a high-frequency trading app like Robinhood, built on top of Rails, and how it proves it can scale, managing not only over a complex HTTP API but also communicating over an internal protocol TCP with one New York Stock Exchange server by making use of Remote Procedure Calls (RPC) with RabbitMQ to be able to manage transactional messages (orders).

So, how can we make use of Rails to deliver a huge amount of updates (through WSS) and have solid transactions (through HTTPS)?
