Fellow finance guy/amateur python coder here. I, too, struggle to think of startup ideas.
Have you thought about joining a startup? I know some of the larger ones need financial analysts (Uber comes to mind). It's always in the back of my mind.
Hey, you have no email in the profile, you mind if you shoot me one? I think it would be nice to network with a fellow finance pythonista.
To your point: maybe in US yes, but in Europe I have been trying 2 years almost and nothing. Startups don't have the budget to support a full finance guy and when they have, they tend to prefer locals (like good luck getting a finance job in a German startup).
