What is High-Frequency Trading?

High-frequency trading is a distinct type of algorithmic trading distinguished by holding securities for extremely short durations such as micro or milliseconds necessitates the use of powerful computers and exceptional network infrastructure to process data at lightning-fast speeds.

For HFT to function effectively, it must achieve low-latency response times and handle high trading volumes. Additionally, it relies on tick-by-tick data and a thorough understanding of market microstructure.

High-Frequency Trading estimated at USD 6463.3 Million in the year 2022, is projected to reach a revised size of USD 12590 Million by 2028, growing at a CAGR of 11.8% during the forecast period 2022-2028. ⁽¹⁾

HFT strategies are mainly divided into market making, statistical arbitrage, momentum trading, mean-reversion strategies, long-short selling, breakout etc.

Also, we have this video below for a better understanding of HFT and the related trading styles, that is, Low-Frequency trading and Medium-Frequency trading.

Now we will move to the next section in which we will briefly discuss the impact of High-Frequency trading covering the key areas where it is helpful.

Impact of High-Frequency Trading

High-frequency trading helps with the following: ⁽²⁾

Increasing liquidity

Liquidity refers to the ability and ease with which assets can be converted into cash without affecting the current asset price in the market to a great extent. Market liquidity refers to the extent to which a market allows assets such as stocks, bonds, or derivative products, to be bought and sold without paying a huge bid-ask spread. As the number of trades entered increases, orders may lead to more liquidity in the market.

Spread narrowing

The HFT traders may provide the most competitive bid-ask prices, which may result in the narrowing of bid-ask spreads. Spread is the difference between the immediate best ask price and the immediate best bid price of a security. It is the difference between the lowest price a seller is willing to accept and the highest price a buyer is willing to pay for an asset. If the bid price of a stock is $49 and the ask price is $50, then the bid-ask spread is $1.

Improving market efficiency

HFT algorithms incorporate numerous chunks of information in a short time. High-frequency trading technology is the fastest as it can process market information and invest in gainful assets within a fraction of a second.  Thus, the market reflects prices quickly and accurately with no human glitches. Algorithms are free of human emotions (unlike humans) and thus, put forth the market information logically for gainful investing.

Now that we know quite a bit about HFT, let us find out next what makes an individual so attracted towards working at an HFT firm.
