Understanding the Basics of Automated Trading Systems

Automated trading systems are a form of automated software that is used by traders to place trades in the market. They work by using algorithms and mathematical models to identify patterns on price charts and make predictions about future price movements. Automated trading systems can be created by professional developers or amateur traders with little programming knowledge.

What is an Automated Trading System?

An automated trading system is a software program that uses pre-programmed rules to make trades on your behalf.

Automated Trading Systems (ATSs) are used by retail traders, institutional traders, and financial institutions alike. They can be used for both long-term and short-term investment strategies and are often referred to as high-frequency trading systems because they can execute thousands of trades per second.

How Does It Work?

The first step is to write the code for your system. This involves writing algorithms that can be run on a computer, and it’s usually done in C++ or Python. After you’ve written your code, it needs to be tested: you need to make sure that every possible combination of inputs produces an expected output (for example, my program should be able to give me an answer by monitoring the market value and making predictions.). Next comes deployment: once we’re happy with the results from our testing phase, we deploy our system into production where it will start making trades based on its algorithm!

Automated trading systems, sometimes referred to as algorithmic trading systems, make money by buying and selling assets automatically. These systems are unique because they tend to be more efficient than manual trades.

Pros and Cons of Automated Trading Systems

  • Reduced risk of human error. Because automated trading systems are designed to run without any human intervention, they can be trusted to make decisions without emotion or bias.
  • Automated trading systems provide you with the freedom to trade 24 hours a day, 7 days a week. You will never have to worry about missing a market opportunity because your automated trading system never sleeps or takes vacations. Position yourself for global markets while you sleep and enjoy those long, relaxing weekends!


  • Lack of flexibility in response times due to pre-programmed rules that may not always be appropriate for current market conditions (e.g., buying/selling too early or too late). This is where having an experienced developer who understands the market well comes into play; their knowledge allows them t optimize your system’s performance by making changes according to what works best under different circumstances.

The Costs of Developing an Automated Trading System

The cost of developing an automated trading system depends on the complexity of the system, how much you are willing to pay for it, and how quickly you want to get it done. You can visit this page to read more about costs.

The more complex your automated trading system is, the more time it will take to develop and test. If you have a simple idea that can be coded in a few days or weeks then obviously your costs will be less than if your idea takes months or years to develop into something usable by traders who want results now!

Types of Automated Trading Systems

There are several types of ATS available, each with its own unique features and advantages.

Trend-following ATS

Trend-following ATS is the most popular type of automated trading system. These systems are designed to identify trends in the market and generate buy or sell signals based on those trends. Trend-following systems work well in markets that have a clear and sustained trend. These systems are easy to implement and require minimal input from the trader.

Mean-reversion ATS

Mean-reversion ATS is designed to identify market conditions where the price of a security has moved too far away from its long-term average. These systems generate buy or sell signals based on the expectation that the price will revert to its mean. Mean-reversion ATS works well in markets that are range-bound and where the price tends to fluctuate around a long-term average.

High-frequency trading (HFT) ATS

HFT ATS is designed to take advantage of small price movements in the market by executing trades at lightning-fast speeds. These systems use complex algorithms to analyze market data and execute trades in a matter of microseconds. HFT ATS is typically used by institutional traders and requires significant resources to implement.

News-based ATS

News-based ATS is designed to analyze news and other market information to identify trading opportunities. These systems use natural language processing (NLP) algorithms to analyze news articles, social media feeds, and other sources of information to generate trading signals. News-based ATS are particularly effective in markets that are sensitive to news and other events.

Arbitrage ATS

Arbitrage ATS are designed to identify price discrepancies in the market and generate trades that take advantage of those discrepancies. These systems typically analyze prices across different markets or different securities to find opportunities for profit. Arbitrage ATS requires significant resources to implement and is typically used by institutional traders.

Regulations and Security

Regulatory organizations such as the United States Securities and Exchange Commission (SEC) or the Financial Industry Regulatory Authority (FINRA) mandate that both types of trading venues must maintain certain safeguards to protect investors’ interests. Automated trading systems are subject to these same regulations, including requirements for fair order execution, safeguarding customer records, providing clear quarterly statements, and full disclosure of transaction fees.


In conclusion, automated trading systems are becoming increasingly popular due to their ability to increase the trader’s productivity. Whether a system is composed of manual or automated strategies, it should allow traders to maximize profits while minimizing risk. Utilizing trading automation tools is highly recommended since they can provide a faster, more efficient approach to buying and selling securities in the markets.

Moreover, automated trading systems are easy to use, cost-effective, and provide insight into market trends that can improve a trader’s decision-making process. As long as the strategies employed by an automated system are monitored regularly and intelligently implemented by the user, such systems can yield good results with minimized risks.
