High Frequency Systems

Build ultra-low latency trading systems. Master Kernel Bypass, C++ optimization, and FPGA concepts for microsecond execution.

In High Frequency Trading (HFT), speed is everything. This course teaches the systems engineering behind trading platforms. You will learn to bypass the OS kernel using techniques like DPDK and Solarflare to process network packets faster. Master C++ optimization: cache locality, lock-free data structures, and avoiding heap allocations. We also introduce FPGA concepts for hardware acceleration. This is extreme engineering for the fastest markets in the world.
