What Is Algorithmic Trading?
Algorithmic trading is a method of buying and selling in the stock market using computer programs. These programs follow a set of rules to decide when, what, and how much to trade.
In short, it removes guesswork and human emotion. Instead, it uses logic, speed, and real-time data.
Why It Matters in the UK
London is one of the world’s biggest financial centres. Every day, thousands of trades happen on UK exchanges. Many of these tasks are now handled by algorithms, rather than people.
That’s because:
- Algorithms are faster
- They make fewer mistakes
- They react to the market in real-time
With more investors utilising technology, algorithmic trading has become a significant component of how the UK market operates.
How Algorithmic Trading Works
Here’s how it works, in simple terms:
- A strategy is created based on past data or market conditions.
- The algorithm is programmed using simple rules (like buy if price drops 5%).
- The system operates 24/7, continuously monitoring the markets.
- When a condition is met, a trade is made automatically, with no delay.
This all happens in milliseconds.
Who Uses It?
Algorithmic trading is not just for big banks. Many types of traders use it:
- Investment banks – for fast and high-volume trading.
- Hedge funds – to find price gaps.
- Retail traders – using tools like MetaTrader or TradingView.
- Institutional investors – to handle large amounts at better prices.
- Forex and commodity traders – for global market access.
Benefits of Algorithmic Trading
There are plenty of reasons why this method is becoming the norm:
Speed: Instant trades give better pricing.
Accuracy: Fewer errors than manual trading.
Lower Costs: Saves on brokerage and time.
Emotion-Free: No panic buying or selling.
Backtesting: Test before going live.
More Opportunities: Monitor multiple markets at once.
Challenges to Be Aware Of
Nothing is perfect. Algo trading comes with some risks:
Flash crashes – quick drops caused by destructive code or too many trades.
Tech glitches – bugs or system issues.
Complex rules – harder to understand or fix if something goes wrong.
Over-optimisation – relying too much on past data.
Still, when used well, the benefits usually outweigh the risks.
