Lesson 8: 3.7: High-Frequency Trading (HFT) and Microstructure
Examine high-frequency quoting, co-location, rebate arbitrage, and flash crashes.
1. The HFT Landscape
High-Frequency Trading (HFT) utilizes ultra-low-latency infrastructure, sub-millisecond networks, and custom hardware (FPGAs) to trade at speed. HFT algorithms compete for queue position and rapid execution.
Strategies include market making, latency arbitrage (exploiting microsecond price differences across different cities), and maker-taker rebate capture.
★ System Risk: System cross-interactions and structural feedback loops can cause momentary liquidity vacuums, triggering Flash Crashes.
