Introduction to High-Frequency Trading
High-Frequency Trading (HFT) in US stock markets refers to the use of sophisticated algorithms and powerful computers to execute large volumes of trades at extremely high speeds, often in fractions of a second. HFT strategies capitalize on small price discrepancies and market inefficiencies, aiming for quick profits. This approach requires advanced technology, direct market access, and low-latency connections, making it a dominant force in modern financial markets and significantly impacting liquidity and volatility.

❓ Frequently Asked Questions
What is high-frequency trading (HFT)?
HFT uses powerful computers and algorithms to execute a large number of orders in fractions of a second, aiming to profit from tiny price moves and market microstructure.
How does HFT differ from traditional trading?
HFT relies on ultra-fast execution, automated decision-making, and very short holding periods, while traditional trading is typically slower, involves fewer trades, and may hold positions longer.
What are common HFT strategies?
Strategies include market making (providing liquidity by posting bids/asks), latency/arbitrage (exploiting speed differences across venues), and short-term statistical arbitrage.
Why are latency and proximity to exchanges important in HFT?
Lower latency and co-location near exchange servers reduce the time it takes to receive data and place orders, giving a competitive edge.
