Ask HN: How can I get into Finance/HFT development?

Hi Hn, I'm a self taught web developer, have experience with back and front end (node and python mostly), and have also been interested in finance as a hobby (I trade casually). I don't have any higher education in CS or Math but I think I'm rather rational by nature and I was pretty good at math back when I was still in school. I also love learning so I'll be glad to take on whatever skills/knowledge I might missing. I feel like the intersection of those two interests might be something I'd like to pursue further so I was wondering if anyone here had any insight/ideas/experience as to how I could get into that world, if there are any books you could suggest, required skills/languages in use, anything that could point me in the right direction really. Thanks!
