Lucas and Luna explore why OCaml, a 30-year-old functional programming language, has become a quiet powerhouse in financial trading systems. From Jane Street's massive adoption to its role in high-frequency trading, they unpack the language's unique strengths: strong static typing, immutability, and a pragmatic approach that balances safety with performance. This episode dives into how OCaml's type system catches bugs before they happen, why its performance rivals C++, and how it manages the complexity of modern trading infrastructure. With a look at real-world use cases and the trade-offs that come with choosing functional programming, the hosts discuss why OCaml is gaining traction beyond finance, in areas like compilers and formal verification. If you're curious about languages that prioritize correctness without sacrificing speed, this conversation is for you.
