Lesson 0: 14.0: Introduction to High-Frequency Trading (HFT)
Explore the modern microstructure of algorithmic HFT, sub-millisecond execution, and quantitative market design.
1. Defining High-Frequency Trading
High-Frequency Trading (HFT) refers to automated trading strategies executed by specialized quantitative firms utilizing ultra-low latency infrastructure, high-speed networks, and high message-to-trade ratios.
HFT firms hold positions for extremely short timeframes (seconds to milliseconds) and rarely hold unhedged overnight positions. They generate profits by capturing microscopic pricing discrepancies millions of times per day.
★ Market Footprint: HFT firms account for approximately 50% of US equity trading volume and over 60% of futures volume.
2. Key HFT Strategy Archetypes
• Automated Market Making: Continuously placing passive limit orders on both sides of the order book to capture the bid-ask spread.
• Statistical & Cross-Venue Arbitrage: Exploiting temporary price dislocations for the same asset across different exchanges.
• Momentum Ignition & Order Flow Sensing: Identifying large institutional order execution footprints in real time.
