Here are some leading financial programming languages that make an individual thrive in the fintech industry.

Financial programming languages are programming languages designed specifically for financial applications, such as quantitative finance, risk management, and financial modeling. Here are five specialized financial programming languages.

1. Rust- Rust seems to be the most valuable one to learn. Although it's not yet widely used in finance, there are some areas where it's gaining traction, especially in the crypto industry. Even systematic hedge funds are willing to hire candidates without prior Rust experience due to its high demand.
2. OCAML This programming language is a close second to Rust in Stack Overflow's pay statistics, and may even earn significantly more in finance, given its adoption by a major hedge fund.
3. Ada – Ada is a popular language in Europe, particularly in France where it was initially developed by a Frenchman. French bank BNP Paribas and Dutch prop traders Deep Blue Capital are among the major hirers of Ada developers.
4. Slang- Slang is a programming language that may not be as valuable as the others on this list and is mostly associated with Goldman Sachs. It's not recommended unless you're set on a career with the company.
5. Ruby- Ruby, which was developed in the 1990s, is a more popular language among fintech, with several high-paying jobs available for Ruby developers.
