Yeah, quite impressive language to make the backbone of all your systems.

I doubt that it is used for actual trading. Maybe the OP can elaborate what the live infrastructure and backtesting setup look like?

> I doubt that it is used for actual trading.

Do you have a basis for that claim?

JS have developed tons of libraries and tools for OCaml development, and new developers and quants that they hire go through an OCaml bootcamp to come up to speed. They put lots of work into the OCaml compiler, and in blog posts about that work they talk about why this is useful for trading. Maybe I'm missing something crucial, but I think it's more likely that you just don't know what you're talking about.

Of course they use it for trading and everything around for many years.

[shaklee3]

they use it for the control plane. it's clearly not used for actually submitting trades.

[throw20220422]

Do you mean this tool, or OCaml? They are definitely writing their actual trading systems in OCaml, they have been publicizing this for many years.

[b20000]

that is what i thought. the actual trading code is probably in c or c++ or is in an fpga being controlled by the trading code.

[b20000]

cool, so how about the OP shares the details of how they use it for trading?

That's largely what their excellent Signals & Threads podcast is about.
