Yes, FPGAs are the absolute gold standard for High-Frequency Trading (HFT) , but there is a massive catch: you cannot use cheap hobbyist boards to do it. [ 1 , 2 ] In true HFT, a software-based system (CPU/OS) takes a few microseconds to process market data and send a trade. An FPGA-based setup bypasses the operating system entirely and executes a "tick-to-trade" loop in 10 to 300 nanoseconds . [ 1 , 2 , 3 ] However, the hardware architecture required to do this makes an actual HFT setup vastly different from an educational experiment. How a Real FPGA HFT Setup Works In a professional setup, the FPGA acts as the Network Interface Card (NIC) . [ 1 ] Direct Fiber Ingestion: Fiber optic cables from the stock exchange plug directly into high-speed QSFP network cages on the FPGA board. Hardware Network Stack: The FPGA logic decodes the incoming Ethernet, IP, and UDP raw packets directly in its gates. Instant Logic & Execution: The FPGA instantly updates an internal live...
