Unless your job directly involves managing accounts I would not put personal trading on a resume. Note: this is not true if it was your primary means of employment for a prolonged period of time. In this case it explains what would otherwise look like an extended unemployment period on your resume. I would always include entrepreneurship on your resume. Even if you did not succeed it says a lot about your personality.

Entrepreneurship: Name, Sole proprietorship/ Partner

? Description of business

? Garnered five-digit figure profits

? Reason quit? Sold? Value?
