But the point is you are not doing physics, you are at best tweaking some pre existing model.

I did it in the past while consulting for a major bank, I studied CS, not physics, and I haven't seen any applied physics in banks.

They hire young people studying physics because they are not scared of working "with numbers", but when you past 40 you're not scared of anything anymore and you'll find there a majority of people with a degree in economy, once you grasped the basics, you can do the job.

While the physics student hopes to be a real physicist someday in the future and stop working on trading models as soon as somethings better comes up.
