What most people know about high-frequency trading (HFT) is that it uses advanced algorithms and that trades are executed at lightning speeds. The rest is less clear. Meanwhile, HFT seems to be a very curious field with abnormally high returns. So it is, at least, worth knowing what it is exactly and how you can get started in it.
What Is HFT Exactly?
High-frequency trading (HFT) is centered on speed and precision. It uses advanced algorithms and super-fast computers to execute a massive number of trades in milliseconds (even microseconds). The idea behind it is to profit by capitalizing on tiny price differences. These are the differences that exist in the market for just a brief moment. Instead of holding onto stocks or other assets for days or weeks, HFT firms might only hold them for a few seconds. Then, they sell them off again.
Three factors that play the most important role here are speed, volume, and automation.
- Speed
In HFT, every microsecond matters. This is why firms invest heavily in fpga hardware design to ensure their trades happen faster than anyone else’s. Besides the use of FPGA, they often place servers close to the exchange to shave off those precious milliseconds.
Volume
HFT isn’t the type of trading where you make huge profits on a single trade. It actually implies executing thousands — or even millions — of trades each day. Each of these is aiming to make a tiny profit and over time, these small gains add up to bigger amounts.
Automation
Everything in HFT is automated. Algorithms make all the trading decisions, scan the markets for opportunities, place trades, and adjust positions. This is, perhaps, what makes it so friendly to beginners. On the one hand, you need to purchase all those tech solutions. On the other hand though, if you can afford the necessary tech, you are actually good to go. No (okay, little) human intervention is required. These algorithms will do the job. That is, they’ll spot and exploit the smallest inefficiencies in the market.
Why Does HFT Matter?
If we try to put HFT in a broader context, we would need to cover, at least, three aspects in relation to it. The first one is market making. The thing is that HFT firms often act as market makers — they’re ready to buy or sell a particular stock. As a result, there’s always enough liquidity in the market because there are enough buyers and sellers to keep things moving smoothly.
Besides, HFT firms also engage in arbitrage. Here, they take advantage of price differences for the same asset across different markets. For example, if a stock is priced higher on one exchange than another, an HFT firm might buy on the cheaper exchange and sell on the more expensive one.
And one more trick HFT firms use is latency arbitrage. Here, they likewise capitalize on tiny delays in the transmission of market data.
How To Enter High-Frequency Trading: A Full Guide
Understand the Regulatory Landscape
So if you are determined to try your hand at it, you’ll need to begin with understanding the legal implications. First, identify the regulatory bodies that govern financial markets in the regions in which you plan to operate. For example, in the USA, it’s the SEC, in the UK — the FCA.
It’s really hard to sort it all out on your own, so do engage legal experts if possible. They must have some experience specifically in HFT. They can help you understand the nuances of regulations like the MiFID II in Europe. For example, there are specific requirements for algorithmic trading (e.g., the need for stress testing and ensuring algorithms don’t contribute to market instability). Below are a few glimpses into it.
| Region | Regulatory Body | Key Regulations |
| USA | Securities and Exchange Commission (SEC) | Regulation NMS, Rule 15c3-5, Market Access Rule |
| UK | Financial Conduct Authority (FCA) | MiFID II, Algorithmic Trading Requirements |
| Europe | European Securities and Markets Authority (ESMA) | MiFID II, Market Abuse Regulation (MAR) |
| Asia | Various (e.g., SFC in Hong Kong, MAS in Singapore) | Local regulations, often influenced by MiFID II |
Develop a Solid Business Plan
As with anything, you need to have clear objectives. Beyond just setting profit targets, consider your firm’s unique positioning. Will you focus on market making, arbitrage, or liquidity provision? Each strategy requires different resources and implies varying levels of risk and reward.
Next, estimate your capital requirements, including detailed breakdowns for
- technology infrastructure (e.g., FPGA hardware, low-latency networks)
- human resources (e.g., quant developers, traders, compliance officers)
- operational expenses
- contingencies (e.g., legal fees, fines).
If you are going to pitch your business idea to investors, emphasize your competitive edge. The latter can be rooted in
- strong proprietary algorithms
- exclusive data feeds
- advanced infrastructure like FPGA-based hardware acceleration.
You should also provide detailed projections of expected returns and risk management strategies.
Build the Right Team
First and foremost, you’ll need quants and developers, of course. But that’s not all. It’s likewise wise to hire professionals with experience in high-frequency trading specifically. They should understand
- market microstructure
- order book dynamics
- the nuances of different asset classes.
Think about how you’ll inspire collaboration., too
Secure Funding
Ideally, you should secure funding from sources that understand the high-risk, high-reward nature of HFT. Whatever it is, be transparent about your plans and expectations.
When you’ve got your budget, prioritize investments in low-latency infrastructure and algorithm development. Allocate a portion of the budget for R&D. You’ll want to refine algorithms and be able to explore new trading opportunities. Plus, it’s smart to set aside funds for regulatory fines or legal disputes.
Acquire and Optimize Technology Infrastructure
This is perhaps the most important step of all. You should invest in low-latency infrastructure that includes colocation services. Your servers must be physically located as close as possible to exchange data centers. Use high-performance computing solutions and optimize software for speed.
We’ve already mentioned the FPGA technology for hardware acceleration but let’s take a closer look at it now. The central value of FPGAs is that they execute trades with extremely low latency, significantly faster than traditional CPUs. If you customize the hardware logic to your specific trading algorithms, you’ll achieve microsecond-level execution speeds.
Besides, develop algorithms tailored to specific markets and trading strategies. You can use machine learning models to help you. The algorithms must be optimized for the particular asset classes you intend to trade (e.g., equities, futures, etc.).
Finally, it may be useful to subscribe to premium, real-time data feeds. You can even integrate these feeds with advanced analytics platforms.
Develop and Test Trading Strategies
One of the trickiest tasks is to find a working strategy you’ll stick to. There are many ways to do this but two of them are absolutely essential:
- quantitative research
- algorithm testing.
And don’t forget about risk management. Beyond basic risk controls like stop-loss orders, you may want to likewise implement dynamic risk management systems. These adjust trading limits based on real-time market conditions and your firm’s exposure. Ideally, you should likewise use machine learning — it’ll predict potential losses and adjust strategies.
Set Up Trading Infrastructure
The primary concern is to choose the trading platform and there are actually two avenues here. The first is to choose an off-the-shelf solution. If you go this way, choose one that offers
- low-latency execution
- real-time analytics
- robust security features.
Alternatively, you could order the development of a custom platform and that’s the best option if you are serious about HFT.
Then, there are brokerage relationships. It’s really important to only partner with those brokerages that offer direct market access (DMA). They should be able to handle the high volume and speed of trades typical in HFT, too. Before entering any partnerships, ask them about the risk management tools they use.
Latency optimization has already been mentioned several times here but it’s indeed one of your central tasks. You’ll need to continuously optimize every component of your infrastructure (e.g., network routes, server processing times). So do use network optimization tools and FPGA-based systems.
Launch and Scale
The thing with HFT is that it’s pretty risky. Your task is thus to try to minimize these risks. The simplest thing you can do is to roll out your trading strategies gradually. For example, you can start with lower trade volumes and see how it goes.
To monitor performance, you should set up real-time monitoring systems. These will track the performance of your
- algorithms
- infrastructure
- trading outcomes.
Don’t just collect the data though. Use it to fine-tune your strategies.
Once your initial strategies are proven, you can increase trade volumes. For example, you may want to expand into new asset classes or enter new markets then. It may also be a good idea to develop additional algorithms to diversify your trading portfolio.
Compliance and Risk Management
Always keep compliance in mind. It’s hard to remember everything so implement automated systems for that. Plus, regularly update your compliance policies because there can be changes in laws and regulations.
Why HFT, By the Way?
We’ve said quite a lot about HOW to make your first steps in HFT. But WHY would you even consider that? In general terms, it’s always about opportunities, of course. But what are these opportunities exactly?
High Profit Potential
You enter trading for profit in the first place. As to HFT, its profit potential is pretty high. Yes, individual profits per trade are minimal. But the cumulative effect can be substantial.
Thus, an HFT firm that uses algorithms to identify price discrepancies between related assets can swiftly execute trades across different markets. It can exploit a slight difference in the price of a stock listed on two exchanges within milliseconds. As it does so, it is generating profits that add up quickly over thousands of trades.
Leading Technological Innovation
HFT is where cool tech things are now happening. Very often, such firms are pioneering advancements that shape market behavior. The need for speed and precision drives innovation and you have a chance to become a part of it.
The development of low-latency trading systems requires not just fast algorithms but also optimized network infrastructure. This is why HFT firms work with hardware and software engineers to reduce the time it takes for a trade order to be executed. They often compete in mere microseconds in this domain. Such innovations lead to broader applications in other financial sectors.
Multiple Revenue Streams
As an HFT firm, you’ll be able to diversify your income if you employ various trading strategies (e.g., market making and arbitrage). That is, you might engage in market making, where you quote buy and sell prices for securities. Here, you’ll earn a spread on each transaction.
Simultaneously, you could pursue arbitrage opportunities. For example, you’d exploit differences in prices between related assets across different markets. This way, risks will be a bit lower and revenues will be a bit more predictable.
Competitive Edge in Information Processing
To be competitive, HFT firms use real-time data and advanced analytics. They learn to process vast amounts of data and execute trades faster than competitors. It is key to staying profitable in this space. And it is also a valuable expertise that’ll come in handy in other spheres.
Enhancing Market Efficiency
Last but not least, the proponents of HFT often insist that it contributes to market efficiency. They explain this by the fact that this type of trading narrows bid-ask spreads and ensures prices reflect current market conditions. Of course, this can be debated but HFT is, indeed, able to enhance liquidity and price accuracy (at least, to an extent).
For example, an HFT firm detects and acts on minor pricing errors between exchanges. It quickly buys and sells the asset across these platforms and by doing so, helps align prices. As a result, markets become more efficient and the cost of trading is reduced for all participants.
To sum it up, HFT is the type of trading that is, above all else, centered on
- speed
- automation
- volume.
Your role in it is minimal. It mainly confines to upgrading and optimizing your tech so that it outperforms the tech of other participants. If that sounds exciting to you and if you have the resources to invest in custom tech development, then HFT is, at least, worth exploring. You now know how to make the first steps in it. The next step is to consult a good fpga hardware design agency and take action.
