The coding language used by the most elite developers in finance

If you're learning a coding language with a view to becoming employable in a technology role in financial services, should you choose something like Python , which is well-used across the industry, or should you go for something a little more obscure?

A Substack blog post  at the weekend argued for the obscurity route. We've already looked at the value of languages like K and Q for finance jobs, but there's also merit to learning functional programming languages like Clojure, F#, Scala, Elixir, and...OCaml.

OCaml is the language used by Jane Street, the quantitative market making firm that last year paid its lucky graduate trainees a $200k annual base salary, plus a $100k sign-on bonus, plus a $100k-$150k guaranteed performance bonus. Jane Street's revenues in the first quarter alone of 2020 were greater than Citadel Securities' for the entire year.
