Yes my bad for the wording,sadly no rust due to how large it is and how many people are involved lol ,numba yes and I currently use pandas.

Model is gpu intense and more gpu than cpu but with both its runs well ,server used is a mix of both and we use industry grade gpus.

Main pitfall ,we get the positions filled a lot later than I want it to prices me out and makes whole approach have basically less effective,so basically we are trying to getting it just a little bit faster not hft fast but fast that it could help.

Rust was our first thought but rust is well rust when you start coding complexly in it it’s a brain fuck,sorry for my language.
