Programming Languages Used in Finance – FinSMEs


What type of job do you want in the finance sector? Do you want to be an analyst and crunch numbers all day, or would you prefer the fast-paced environment of a trader? Moreover, do you aspire to work in equity research, risk management, or something else?

Depending on your aspirations, you have many choices, but all of them share a few key elements in common. The roles come with their own requirements and skill sets, but many are common across the finance industry. Each has its own challenges and rewards. Given this, it’s important to understand what kind of job you want first and then decide on the appropriate skill sets needed for it. One of these is learning the right programming languages used in finance. Let’s take a look at some of them. In order to do so, we need to first examine what we mean by a programming language.

What Is a Programming Language?

There are a few different ways to think about a programming language; however, in the context of finance, it is any language that enables a person to write instructions for a computer. The instructions are then translated and executed by the computer. By writing the instructions, you can program a computer to complete specific finance-related tasks, such as running calculations, managing databases, and executing other functions that would normally be done by humans in earlier decades. Learning a programming language doesn’t have to be hard! Many students of programming find the process to be rather straightforward, though that varies greatly according to the language. Fortunately, there is plenty of coding help available. One of the best ways to learn coding is to take a course in a specific language. The good news is that a number of programming assignment services like Assignment Core offer professional assistance when you need someone to do coding homework for you or a helping hand to find more time to study coding.

When choosing a programming language for finance, you have a few great options for languages that will be most useful. Here are a few of them:


Used in many different fields, Python is one of the most popular programming languages in the world. It is also one of the most frequently used in finance. The language is suitable for beginners and has a large community of users. This means that you can more easily find help and receive feedback with any issues you may be facing. In terms of specializations, Python is most popular in the data science, artificial intelligence, and financial engineering domains. It is suitable for these areas owing to its strength in data science, mathematical computations, and natural language processing. As a general-purpose programming language, Python can be used to write any type of program, from web apps to websites. It is also used for data analysis, machine learning, and scientific computing.


Java is another popular programming language used in finance. It is the most commonly used language for large-scale enterprise applications owing to its scalability. It is a general-purpose language suitable for any kind of software development. Java is a modular language, which means programs are broken into smaller pieces that can be developed independently from each other. This makes the development process much more streamlined. Java is an object-oriented language, which means that programming is done with an emphasis on objects. For example, if a car were considered as an object, it would contain information about its make, model, and color. Object-oriented programming assigns attributes to blocks of chunks of information called objects. This is helpful, as it is easier to break down complex problems into smaller, more manageable pieces. As a general-purpose programming language, Java can be used to write any type of program. However, it is primarily used for enterprise applications, such as websites, business systems, and mobile apps.


C++ is a general-purpose, high-level programming language used in many domains. It is an important language in finance because it is suitable for high-performance computing. High-performance computing is the process of using advanced computer technologies to solve complex problems. C++ is derived from another programming language called C. C++ adds object-oriented programming and other advanced features. These make it more suitable for complicated tasks, such as modeling securities. C++ is a compiled language, which means that programs are translated into machine-readable code before they are executed. Compiled programming languages are more efficient than interpreted ones, such as Python, because they require fewer computing resources. C++ is often used for graphical user interfaces, mathematical computations, and computer hardware applications.


SQL is the language used to communicate with databases. In finance, databases are used to store information about assets, clients, and other aspects of trading. They also store the results of mathematical models and statistics. The most common database in finance is SQL, which is why knowing how to use SQL is an important skill for finance professionals. While SQL can be used to write queries, as well as to read data, it is better to learn other programming languages for the latter. This is because SQL is designed for one-off tasks and not for building applications. 

Summing Up 

Several additional programming languages are used in finance, so it’s important to research which languages are most common in the subdiscipline you plan to enter. By knowing which language is suitable for your role, you can develop exceptional skills to set yourself up for success in your career.
