HIGH-FREQUENCY TRADING (HTF) DEFINITION AND BASICS

High-frequency trading (HFT) is a type of algorithmic trading that uses computer programs to execute trades at high speeds, on the order of milliseconds or microseconds. HFT firms use advanced algorithms and powerful computer systems to analyze large amounts of market data and make trades based on that analysis. This allows HFT firms to take advantage of small price discrepancies and make large profits in a short amount of time. While HFT can provide liquidity to financial markets, some critics argue that it can also lead to market instability and increased volatility.

 

HFT firms typically use low-latency networking, which reduces the time it takes for data to travel between the HFT firm’s computers and the exchange’s computers, to gain an advantage over other traders. They also often use co-location services, which allow them to physically locate their servers in the same data center as the exchange’s servers to reduce the distance data has to travel.

 

HFT firms also use a variety of other techniques to gain an edge in the market, such as using order types that give them priority over other traders, or using dark pools, which are private exchanges where trades are conducted anonymously.

 

HFT is controversial because it has been blamed for increasing market volatility and for exacerbating market crashes like the one that occurred on May 6, 2010, known as the “flash crash.” This is because HFT algorithms can create a feedback loop where they react to their own trades, leading to rapid and significant price movements. Additionally, many critics argue that HFT gives an unfair advantage to the firms that use it, allowing them to make large profits at the expense of other traders. However, proponents of HFT argue that it provides liquidity to financial markets, making them more efficient and helping to reduce volatility.

 

HIGH-FREQUENCY TRADING (HTF) – FREE AND OPEN SOURCE ALGORITHMS, LIBRARIES AND STRATEGIES

There are several open-source high-frequency trading (HFT) strategy algorithms and source codes available online. However, it is important to note that while the code may be publicly available, creating a successful and profitable HFT strategy requires a deep understanding of market dynamics, as well as expertise in programming and quantitative analysis.
