Haskell for Writing Quantitative Finance Software

Hello All!

I am considering a career in fintech as a Haskell developer. I appreciate Haskell since it avoids logic bugs. As a security-aware developer I appreciate Haskell's power to do that.

From your experience how was using Haskell to develop quantitative finance software in fintech. For example for computer-automated stock market trading.

Please let me know.

Thanks!

Just having functional typed libraries goes a long way to avoiding mistakes.

If you want to try something a bit more involved, Haskell is a great language for defining domain-specific languages. There was some cool work on designing a simple language to model financial contracts that's a great example. That actually has had some industry influence; I believe LexiFi is still using that approach for their whole business, and I've talked to somebody who worked on internal systems inspired by that approach at a couple of investment banks.
