What is algorithmic trading and how can you introduce it to your trading strategy?
Algorithmic trading uses algorithms to automate some of the financial trading process. Find out how to use this strategy here.

Algorithmic trading, also known as algo trading, refers to the use of computer algorithms to automate the process of buying and selling financial instruments in the market. These algorithms are based on predefined rules and mathematical models, enabling traders to execute orders at high speed.
This form of trading can lead to decision-making and allows for strategies to be executed in milliseconds. Algorithmic trading is widely used in stock markets, forex, commodities, and even cryptocurrency trading.
How does algorithmic trading work?
In algorithmic trading, traders create or use pre-programmed algorithms that make decisions based on set criteria such as price, volume, or timing. These criteria are usually based on historical data and technical indicators. When the market conditions meet these criteria, the algorithm triggers an automatic trade.
For example, an algorithm might be designed to buy a stock when its price drops below a certain level and sell it when the price rises by a fixed percentage. The speed of execution ensures that the trader can respond to small price movements, which may not be feasible for manual trading.

Why does algorithmic trading appeal to financial traders?
- Speed and efficiency: Algorithms can execute trades much faster than any human could, meaning some traders find themselves better positioned to capitalise on market opportunities.
- Minimising emotional trading: By relying on pre-set rules, algorithmic trading can limit the kinds of human emotions that can lead to mistakes.
- Backtesting: Traders can test their strategies on historical data to see how they would have performed, allowing them to refine their algorithms before risking real money.
- Consistency: Algorithms ensure trades are carried out consistently, according to the defined strategy, without deviation.
Introducing algorithmic trading to your strategy
Those wanting to adopt algorithmic trading could consider the below:
- Define your trading goals: Start by identifying the types of trades you want to automate. Are you looking for short-term, high-frequency trading, or are you aiming to execute fewer, but more substantial trades over a longer period?
- Choose or develop an algorithm: If you're tech-savvy, you might want to code your own algorithm using a programming language like Python. Alternatively, there are many platforms offering pre-built algorithms or user-friendly interfaces for building custom ones.
- Backtest your strategy: Before you implement your algorithm in live markets, it can be useful to backtest it on historical data. This will allow you to evaluate how your strategy performs in various market conditions and refine it as needed.
- Monitor and refine: Even though algorithmic trading is automated; it still requires oversight. Market conditions can change, so it's important to monitor your algorithm's performance and adjust as needed.

Risks of algorithmic trading
While algorithmic trading can be highly effective, it also comes with risks:
- Market volatility: Sudden market fluctuations can lead to significant losses if your algorithm is not designed to handle them.
- Technical failures: Algorithms depend on reliable technology. A system malfunction or internet outage could result in missed opportunities or even unwanted trades.
- Over-optimization: When backtesting, it's easy to fall into the trap of making the algorithm too specific to past data, which may not perform well in real-time market conditions.
Algorithmic trading: A trading approach that blends human and machines
Algorithmic trading can be a powerful tool for those looking to streamline their trading processes, minimise emotional influences, and increase trading efficiency. By taking the time to properly develop, test, and monitor your algorithms, you can introduce this strategy into your trading routine. However, it's essential to be aware of the risks involved and to continually adapt your strategy as market conditions evolve.
