I've been in and out of coding for finance at a few different shops for about 10 years now, and recently have been working more on the front-lines: coming up with my own trades and the software to do those. I can tell you from personal experience that this is a completely different experience than writing code for someone else (a trader) who then is responsible for making/losing the money. Imagine this for a daily routine: 1) oh shit this is awesome: x times $1000000 means i'm going to be so fucking rich! 2) run code live on the XYZ market, trying not to shit bricks 3) hang-on i found a bug in my analysis/data-preprocessing/ML pipeline and i'm not going to be rich. 4) spend hours (or days) fixing bug & re-running analysis 5) go back to 1). After a few months of this one gets seriously fragged.
