High Frequency Trading (HFT): The Need for Speed in Financial Markets

2 min readMar 12, 2023

Are you ready to learn about a lightning-fast world where complex algorithms and advanced trading strategies reign supreme? Welcome to the exciting world of high frequency trading (HFT)!

HFT is the practice of using sophisticated algorithms to buy and sell securities faster than you can say “stock market.” These algorithms use real-time market data, historical data, and other indicators to make split-second decisions about which securities to buy or sell and at what price.

HFT is a major player in financial markets around the globe, accounting for a significant portion of all trades executed on exchanges. In fact, according to data from the TABB Group, HFT firms accounted for 51% of all equity trades in the US in 2019. But what makes HFT so special? It’s all about speed, baby! HFT firms want to execute trades faster than other market participants, giving them the edge to take advantage of small price discrepancies that arise over very short periods of time. These discrepancies, known as “market microstructure” anomalies, can be highly profitable for HFT algorithms that can execute trades in milliseconds or even microseconds.

So what’s the secret to HFT success? Access to the fastest available data, sophisticated algorithms, and high-speed internet connections are all key. But not everyone is a fan of HFT. Critics argue that it can exacerbate market volatility and provide unfair advantages for those with the fastest technology.

Despite the controversy, HFT has become an integral part of modern financial markets. Understanding the basics of HFT is important for anyone interested in finance or investing, as it can have a significant impact on market dynamics and investment strategies.

And don’t worry — we’ll be back with more exciting insights into the world of HFT. Stay tuned!
