# How to get a Job in a High-Frequency Trading Firm?

Working at a high-frequency trading firm is not only thrilling but also quite rewarding, provided you have the knowledge and expertise in the HFT domain. With all the in-depth information regarding working at an HFT firm, this article covers:

High-Frequency Trading is a special category of algorithmic trading characterized by holding period of securities ranging from microseconds to a few minutes. HFT requires powerful computers and excellent network architecture to transact with data at very high speeds. HFT needs to have low-latency response times and high trading volumes for the system to work successfully. HFT also requires tick-by-tick data and a good understanding of the market microstructure.

HFT strategies are mainly divided into market-making, statistical arbitrage, momentum, mean-reversion, long-short, breakout etc. High-Frequency Trading helps in:

• 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 increase, 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 basically the difference between the lowest price a seller is willing to accept and the highest price buyer is willing to pay for an asset. If the bid price of a stock is $49 and 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 the market information and invest in the gainful assets within a fraction of second.  Thus, the market reflects prices quickly and accurately with no human glitch. Algorithms are free of human emotions (unlike humans) and thus, put forth the market information logically for gainful investing.

Moving forward, let us find out the different roles at an HFT firm.

## Roles at HFT Firm

We have a full-blown explanation of different roles at an HFT firm in this article on the Basics of High-Frequency Trading. Mainly there are following four roles at an HFT firm:

• Quant Analyst / Model Developer
• Strategy Developer

Quant Analyst / Model Developer

If you are interested in building models yourself and want to apply for a quant analyst/ model developer role, pick up quantitative skills with working knowledge of using quant tools such as R, Matlab, Python.

Strategy Developer

For strategy developer role, you would be expected to either code strategies, or maintain and modify existing strategies. Most likely you would be working with a quant analyst who would have developed the trading model and you would be required to code the strategy into an execution platform.

For the trading role, your knowledge of finance would be crucial along with your problem-solving abilities. If you are good at puzzles and problem solving, you will enjoy the intricacies and complexities of the financial world.

Core development work which involves maintaining the high-frequency trading platform and coding strategies are usually in C++ or JAVA. Hence, honing your C++ or core development language is definitely essential.

Each role holds due importance with regard to the specialization in the particular field. As an aspiring HFT firm employee, you must find your niche and then apply for the job accordingly.

Let us take a look at the qualifications aspect of an HFT firm employee further.

## Qualifications Required

High-Frequency Trading is an extremely technical discipline and it attracts the very best candidates from varied areas of science and engineering - mathematics, physics, computer science and electronic engineering.

In the developed countries, you need a PhD in CS or physics/maths or an MFE degree to become a quant. Whereas, in the developing economies, an engineering degree in CS/Maths or an MBA in finance from a reputed college also works. Along with that, you surely need a zeal for problem-solving and coding. All this put together, you have a great chance to land up as a quant analyst or a quant developer in a High-Frequency Trading firm.

A key takeaway:

While the degree makes the resume presentable, do not consider it a barrier in case you don’t have one. With a lot of practical work to show in your resume, you can be recognized by the industry as a potential employee.

Although one thing is for sure that, you need to be mentally prepared about investing a significant amount of time in studies (a bookworm? Probably Yes!) and need to make real good practical efforts as a quant trader or a quant developer.

Some of the courses to pursue to qualify for a role at an HFT firm are:

Engineering/MBA

Many High-Frequency Trading candidates are employed straight from college in the relevant area. It's not much different than the campus for the tech industry, although it helps to show something relevant in your resume. It's also quite common for the best undergraduates to be hand-picked from the top technical schools (IITs, BITS, NIT) and then "trained" on the job.

Financial Exchange Experience

Individuals with insight into the inner workings of the exchanges being traded on will be highly sought after as they are likely to be able to help carry out research into new algorithms that can exploit the exchange architecture.

## Skills Needed

The meritocratic approach of High-Frequency Trading firms usually allows significant autonomy in the projects.

If you wish to work with extremely smart and capable individuals, in a self-starting environment, then High-Frequency Trading is probably for you.

For instance, at one of the HFT firms, iRage, you will get to solve some extremely challenging engineering problems and shape the future of this lucrative industry while working alongside other exceptional programmers, quants and traders.

Note: iRage is a known associate of QuantInsti.

Ready to Evolve at a Fast Pace

The role of an HF Trader is very competitive, in the sense that you have to continuously evolve your system. And while being rewarding most of the time, it’s also disheartening when months of hard work and research goes to drain if exchange changes its architecture. At such a time, a new regulatory environment may surface or a competitor may be able to exploit a process at a rate faster than yours. But you need to ensure that you quickly evolve and be mentally prepared to face such adversities.

Entrepreneurial and Meritocratic Mindset

Now, most of the High-Frequency Trading firms are pretty small in size, usually fewer than 100 people. So, you should have a strong entrepreneurial culture and a meritocratic mindset. Given that, the bonus component in total algo trading salary is a multiple of your base pay. Hence, you will need to demonstrate an ability to generate revenue in order to earn that bonus. The flip-side to this process is that often you will be able to "create your own role" within the firm.

Longer Working Hours

Also, you must be prepared to work longer hours than usual. Since such roles often come with longer hours than many might be used to, 10-15 hours per day are not uncommon. The fast-paced growth, intellectual stimulation, and compensation generally outweigh the workload though.

Industrial Expertise in low latency/big data/machine learning

Experts in low latency software development are usually sought after. Expertise in the area of big data or machine learning is another way for you to enter this domain.

For getting hired as a quant trader in a High-Frequency Trading firm, most of the ways require extensive technical skills. These skills need to come from one or more of the hard sciences such as mathematics, physics, computer science or electronic engineering.
