Is employment by a proprietary trading firm or similar workplace typically compatible with becoming a self-employed trader? I have a BS in CompSci, and have recently realized my fascination with financial markets. I am currently educating myself in finance, as well as the math prerequisite to dabbling in machine learning. I have been considering applying for a job in the trading space, as in addition to building capital, this seems like a great opportunity to surround myself with experienced mentors and team members, without having to wander through the maze of advertised mentoring services that may be of questionable value. However, I would not want to bar myself contractually from building a self-employed trading business, and I'm not sure if this type of prohibition is common. I realize that definitive clarity is only possible by reading a specific company's employment contract; I merely want to know whether this is a concern in general. Is it usually permissible for a proprietary trader to manage a personal trading business as well, or at least to start one if and when their employment ends? Is this a path that a significant number of eventually-self-employed traders take?
