The common path in my circle these days is to get a degree in computer science and maybe math. Then you apply to trading firms for internships/jobs. If you get them, great, make 500+ as a newgrad. If you dont, you can use FAANG or unicorns or even SWE roles at hedge funds as a backup and still make 200+.
The thing that makes trading a bit hard to enter is the interview process. A lot of firms test your mental math skills, so you really need to start in high school ideally and do UIL Number Sense (in Texas) or similar contests. Or spend some time freshman year practicing mental math and tricky probability questions. I didn't do this and fell behind and thus am not a trader but instead a SWE.
But a computer science degree is also an excellent backup in case you realize you don't want to do trading or aren't cut out for it.
Traders at Optiver and other reputable firms are for sure making at least that much. Their pay is variable, but I think you generally hit 7 figure annual payouts really fast.
Even new grad software engineers make 350+ at Jane Street, HRT and Citadel. You can easily verify this through levels.fyi. I didn't believe the data until some people I personally know who work here said its true. And of course traders who take on all the risk should have a much higher upside so their pay should be significantly more than 350.
Some paths:
1. get a math degree in college and become a quant
2. apply for a job at a brokerage house, then take the classes to get a brokerage license
3. get a college degree in finance
4. get a college degree in accounting
