How to Build an Exchange

Presented by: Brian Nigito

Electronic exchanges play an important role in the world financial
system, acting as focal points where actors from across the world meet to trade with each other. But building an exchange is a difficult
technical challenge, requiring high transaction rates, low, deterministic response times, fairness, and reliability.

This talk looks at the question of how to design an exchange through the lens of JX, a crossing engine we built at Jane Street in the last two years. Performance plays an interesting role in this design, in that, although the end-to-end latency of the system is not important in and of itself, the ability of individual components of JX to handle
messages rates in the 500k/sec range with latencies in the single-digit microseconds helped us build a replicated system that is both simple and robust.
