Deep dives
Algorithmic Trading: Trading automatically with computers
Algorithmic trading involves using AI to automatically buy and sell stocks or commodities. It is essentially trading done by computers, implementing strategies designed by quants. Humans play oversight and design the strategies, while the computers execute trades based on pre-programmed logic. The main difference from traditional trading is the speed at which it happens, with algorithmic trading being capable of executing thousands of trades per second. It is a data-intensive field, using historical and real-time data to make decisions.
Risk Management in Algorithmic Trading
Risk management is a crucial aspect of algorithmic trading due to the inherent uncertainties and potential for losses. Systemic risks, such as global events like COVID or Black Swan events, can significantly impact the market. Proper risk management involves constantly monitoring and analyzing positions and portfolios, and implementing strategies to minimize exposure to potential losses. Risk management models, such as the Value at Risk (VaR) model, are commonly used to estimate the maximum potential loss within a certain confidence interval. The attitude towards risk management and a culture of reflection and learning from mistakes are also pivotal in mitigating risks.
Data Analysis and Techniques in Algorithmic Trading
Algorithmic trading relies heavily on data analysis and modeling. It requires handling large datasets, both historical and real-time, which are often measured down to the millisecond. Time series analysis is a common technique used, along with various statistical measures and modeling. Data such as asset prices, volume, bid-ask spreads, and interest are analyzed to inform trading strategies. While machine learning is generally less reliable for making price predictions in algorithmic trading, it can be used for other tasks like market sentiment analysis. Python and Julia are popular programming languages for data analysis in this field.
Roles and Skills in Algorithmic Trading
Algorithmic trading companies have a range of roles similar to tech companies, including data engineers, data scientists, data analysts, and developers. Qualifications in math, engineering, statistics, or related fields are advantageous, as they provide a strong foundation in quantitative methods. Programming skills in languages like Python, C++, and Java are essential, along with proficiency in working with databases, both relational and NoSQL. Understanding financial concepts like futures, options, order books, bid-ask spreads, and different types of trades is necessary, although finance knowledge can be taught on the job. Transferable skills in data engineering and analysis are applicable in other industries as well.
In January 2024, six activists were identified by British Police in London, suspected of planning to disrupt the London Stock Exchange through a lock-in. In an attempt to prevent the building from opening for trading. Despite the foiled attempt, the strategy for this protest was inherently flawed. Trading no longer requires a busy exchange with raucous shouting and phone calls to facilitate the flow of investment around the world. Nowadays, machines can trade at a fraction of a second, ingesting huge amounts of real-time data to execute finely tuned-trading strategies. But who programs these trading machines, how do we assess risk when trading at such a high volume and in such short periods of time?
