High-frequency trading (HFT) platforms have revolutionized the financial markets by executing trades at lightning-fast speeds, leveraging advanced algorithms and real-time data analysis. In this article, we will delve into a critical decision-making process for developers and traders: choosing the most suitable programming language and framework for building high-frequency trading platforms. Specifically, we will compare the merits of two prominent contenders, .NET and Rust, in terms of performance, reliability, safety, scalability, and concurrency. By exploring the unique characteristics of these languages, we aim to provide valuable insights to help navigate the complex landscape of building real-time trading systems.

Introduction to high-frequency trading platforms

Understanding high-frequency trading

High-frequency trading (HFT) is the Usain Bolt of the financial world. It involves using powerful algorithms and lightning-fast computers to execute a large number of trades in milliseconds. This breakneck speed allows firms to capitalize on tiny price fluctuations, making small profits on each trade that quickly add up to big bucks.

Importance of real-time capabilities

When it comes to high-frequency trading, time is quite literally money. Real-time capabilities are crucial for HFT platforms to achieve lightning-fast trade execution. Every millisecond counts, and any delays or hiccups can result in missed opportunities or financial losses. This makes the choice of programming language and framework vital for creating a high-performance and efficient HFT platform.

Overview of .NET framework for high-frequency trading
