Most computer programmers who develop new trading algorithms use the programming languages Python or C++. Python and C++ are general-purpose, object-oriented, high-level programming languages. If you work in finance or are pursuing a career in web development or data science, mastering Python and/pr C++ should be a priority. Day traders can benefit from learning how to create trading software with Python and run it in real-time on a virtual server. MetaQuotes Language 4, also known as MQL4, is a programming language specifically for developing, testing, and optimizing your algorithmic trading systems. For traders interested in learning how to create their algorithms, Udemy offers courses designed to help you quickly master both programming languages.
