Limit Order Book & Matching Engine

Codename: vortex

Purpose

Build a high-performance limit order book (LOB) with a price-time priority matching engine. This is the central nervous system of any trading platform.

Constraints

• Language: C++17 minimum. C++20 features permitted where they improve clarity or correctness (concepts, ranges).
• Dependencies: Zero runtime dependencies. Standard library only.
• Build system: CMake. The project must build cleanly with -Wall -Wextra -Wpedantic -Werror.
• Platform: Linux x86_64, little-endian, __builtin_expect and similar compiler intrinsics where justified.
