High Frequency Trading | Investor's Almanac

High frequency trading (HFT) is a type of financial trading that involves using powerful computers and sophisticated algorithms to rapidly execute a large number of trades in a fraction of a second. This practice has been a subject of controversy, with some arguing it provides liquidity to markets and others claiming it contributes to market volatility. According to a report by the Tabb Group, HFT accounts for approximately 50-70% of all trading volume in US equities. The origins of HFT date back to the 1990s, when firms like Citadel and Virtu Financial began developing automated trading systems. Today, HFT is a global phenomenon, with major players like Jane Street and Two Sigma operating in markets around the world. As the use of artificial intelligence and machine learning in HFT continues to grow, the debate over its impact on financial markets is likely to intensify, with some predicting it could lead to a major market crash, while others see it as a key driver of innovation and efficiency in the financial sector.
