Here’s another CppCon future talk we hope you will enjoy – and register today for CppCon 2024!

When Nanoseconds Matter: Ultrafast Trading Systems in C++

Thursday, September 19 10:30 - 12:00 MDT

by David Gross

Summary of the talk:

Achieving low latency in a trading system cannot be an afterthought; it must be an integral part of the design from the very beginning. While low latency programming is sometimes seen under the umbrella of "code optimization", the truth is that most of the work needed to achieve such latency is done upfront, at the design phase. How to translate our knowledge about the CPU and hardware into C++? How to use multiple CPU cores, handle concurrency issues and cost, and stay fast?

In this talk, I will be sharing with you some industry insights on how to design from scratch a low latency trading system. I will be presenting building blocks that application developers can directly re-use when in their trading systems (or some other high performance, highly concurrent applications).

Additionally, we will delve into several algorithms and data structures commonly used in trading systems, and discuss how to optimize them using the latest features available in C++. This session aims to equip you with practical knowledge and techniques to enhance the performance of your systems and make informed decisions about the tools and technologies you choose to employ.
