Benthic - An Exchange in Rust (Matching Engine w/ Margin)

C++ vs Rust Returns! 🚨 Deep Dive into Crypto Exchange Order Execution & Lot Management in Rust (Featuring the Margin Component) 🦀💹 The battle of the titans continues! Following up on our "C++ vs Rust" series, we're diving deep into a real-world application: the core of a cryptocurrency exchange built with Rust. In this video, we meticulously explore the Rust code that drives crucial functionalities, including a look at the Margin Component: Order Matching: See how buy and sell orders are efficiently paired. Margin Component: We'll walk through the design and role of the margin component within the exchange architecture. Real-time Account Updates: Witness how trader balances and asset positions are instantly updated. Detailed Lot Management: We'll trace the lifecycle of open and closed lots within trader subaccounts. "Inflight Lot" Handling: Learn how newly executed trades generate "inflight lots" and how they are matched against existing positions. We'll walk through a practical trading scenario and then dissect the underlying Rust code, demonstrating these concepts in action, including the structure of the margin component. You'll also see how this high-performance system efficiently handles decimal numbers using u64. 🔗 Links: C++ vs Rust - Season 1:    • C++ vs Rust - Season 1 (NodeGraph Example)   GitHub Repository (Rust Code): https://github.com/sadhbh-c0d3/benthic ⏱️ Chapters: 00:00:00 - How does the trading app work? 00:01:13 - Walk-through example trading scenario 00:17:07 - Architecture of the Trading Exchange 00:20:33 - Let's look into the code! 00:29:25 - Order Execution 00:36:11 - Abstracting Order-Matching at Zero-Cost 00:41:13 - Order Book Diagram 00:45:09 - Updating Accounts 00:52:33 - Decimal multiplication with Polynomial Decomposition 00:54:13 - Order Delivery 00:57:30 - Storing Transaction Lots 01:05:07 - Thank you! 💬 What are your thoughts on the design and implementation of margin components in high-performance trading systems?
