Algorithmic Trading Explained in Brief
Algorithmic trading, often referred to as algo-trading, is the process of using computer programs and codes to execute trades automatically based on predefined criteria. This approach allows algo users to automate their trading activities, saving time and effort while potentially improving their outcomes.
Algorithmic trading relies on mathematical models, statistical analyses, and historical data to generate trading signals and execute trades. The algorithms take into account various market parameters, such as price movements, trading volumes, and technical indicators, to identify optimal entry and exit points.
The functionality of a trading algorithm is rooted in its ability to efficiently manage risk and identify potential opportunities. By analysing historical data and current market conditions, the algorithm can predict trends, detect anomalies, and execute trades with a high degree of accuracy. This not only enhances the potential for profitability but also helps traders manage risk more effectively.
Using Algorithmic Trading in Forex
Algorithmic trading can be employed to execute forex trades based on established technical patterns, such as those derived from Bollinger Bands and their interaction with price action. For instance, an algorithm could be designed to initiate a buy order when the price of a currency pair touches the lower Bollinger Band, specifically the 2 standard deviation band, signalling a potential oversold condition and a likely price reversal.
Conversely, the algorithm might be programmed to execute a sell order when the price reaches the upper Bollinger Band, also 2 standard deviations from the Simple Moving Average (SMA), indicating an overbought scenario and a potential price decline. This automated system enables traders to exploit volatility-driven opportunities within the forex market without requiring continuous, manual observation of price fluctuations.
How is Algorithmic Trading Regulated in the UK?
The Financial Conduct Authority (FCA) serves as the primary regulator overseeing brokers offering algorithmic trading within the United Kingdom. The watchdog is tasked with safeguarding the integrity of the local financial markets and ensuring investor protection. The FCA’s regulatory framework largely aligns with the European Union’s Markets in Financial Instruments Directive (MiFID II).
Algorithmic trading is also subject to rules outlined in the FCA’s Market Abuse Regulation (MAR), specifically relating to algorithmic trading strategies. The regulator imposes a set of essential requirements on brokers and financial institutions providing algorithmic trading services to UK clients. These measures are designed to preempt market manipulation, promote transparency, and shield UK customers from the potential hazards associated with automated trading.
- Pre-Trade Controls: Firms must implement effective controls to ensure that algorithmic trading systems are adequately tested and monitored to prevent malfunctions and market disruptions. As outlined in MAR 7A, firms are responsible for ensuring their algorithms do not contribute to disorderly trading conditions.
- Compliance with Market Rules: Algorithms must be programmed to adhere to all pertinent market rules and regulations, including those concerning price manipulation, market abuse, and order execution. The FCA, through its supervisory activities, ensures compliance with these rules.
- Risk Management: Brokers facilitating algorithmic trading are required to establish and maintain robust risk management frameworks to mitigate the potential risks for UK consumers. The FCA’s multi-firm reviews highlight the need for strong governance and oversight of algorithmic trading systems to protect against unintended negative consequences.
Expert Advisors (EAs) and How They Work
Expert Advisors (EAs) are automated trading systems that operate on platforms like MetaTrader 4 (MT4) and MetaTrader 5 (MT5). Also known as “trading bots”, EAs are essentially algorithms that can execute trades on behalf of the user based on predefined criteria. They can analyse market conditions, identify trading opportunities, and place orders without human intervention.
Using Forex Expert Advisors in Practice
Let us imagine you want to create an EA that identifies mean reversion opportunities for the GBP/USD currency pair using the 50-day Exponential Moving Average (EMA). You could either use a pre-built EA or develop one yourself using a programming language like MQL4 or MQL5.
The EA would continuously track the GBP/USD price movements and compare them to the 50-day EMA. If the price deviates significantly from the EMA, indicating a potential mean reversion opportunity, the EA could either notify you or automatically execute a trade. For example, if the price moves 2% above the EMA, the EA might open a sell position, anticipating a return to the mean. Conversely, if the price drops 2% below the EMA, the EA could open a buy position.
You could further customise the EA to manage risk by limiting the trade size to, say, 1% of your account balance. The complexity of the EA can be tailored to your needs, from basic notifications to advanced features like dynamic position sizing or multi-currency monitoring.
Who Uses Algorithmic Trading?
Algorithmic trading is used by a diverse range of market participants, including:
- Scalpers: Traders who aim to profit from small price movements by executing a large number of trades over a short period.
- Day Traders: Traders who open and close positions within the same trading day, using algorithms to identify short-term trading opportunities.
- Institutional Investors: Large financial institutions that use algorithmic trading to execute orders without significantly impacting market prices.
- Retail Traders: Individual traders who use algorithmic trading to automate their trading strategies and reduce the impact of emotional decision-making.
What Trading Strategies Do UK Algorithmic Traders Use?
UK algorithmic traders employ a variety of strategies, each tailored to different market conditions and objectives. Some of the most popular strategies include:
Trend Following
Trend-following strategies aim to capitalise on sustained price movements in a particular direction. Algorithms are programmed to identify trends using technical indicators, such as moving averages, and execute trades in the direction of the trend. For example, if a currency pair like GBP/USD is in a downtrend, the algorithm might execute sell orders, anticipating a further price decline.
Mean Reversion
Mean reversion strategies are based on the idea that prices tend to revert to their mean or average over time. Algorithms are programmed to identify overbought or oversold conditions using indicators like RSI or Bollinger Bands. When a currency pair is deemed overbought, the algorithm might execute a sell order because it anticipates a price correction.
Arbitrage
Arbitrage strategies involve exploiting price discrepancies between different markets or instruments. For example, an algorithm might identify a price difference for GBP/USD on two different trading sites and execute trades to profit from the discrepancy. Arbitrage trading is generally allowed in the UK, but is subject to certain regulations and restrictions.
The FCA actively enforces these regulations, as demonstrated by the £1.7 million fine imposed on Mako Financial Markets Partnership LLP in February 2025. The regulator penalised the firm for compliance system weaknesses that facilitated suspicious dividend arbitrage trading. The case involved £92.2 billion in over-the-counter trades of Danish and Belgian equities and highlighted the regulator’s commitment to preventing market abuse and upholding market integrity.
Market Timing
Market timing strategies aim to predict future price movements based on historical data and market conditions. Algorithms are programmed to analyse patterns and trends, and execute trades based on the predicted direction of the market.
