You might be able to get a job with a prop trading firm? But a big Wall Street firm isn’t going to hire someone who’s been trading their Ameritrade account to high returns just on that alone. You need to prove you have a skill that is scaleable to a big firm.
Plus, no offense, but I seriously doubt that you’re generating the types of returns that would be beneficial to a big firm. In other words, are you trading in substantial size and doing so in a manner that properly accounts for the risk adjusted returns you’re generating? If you’re doing those two things then yes, you should be running a big fund somewhere, but the vast majority of people can’t trade in size and definitely can’t trade in size to high risk adjusted returns….
