No, but this is a bit of a grey area. Trading income is NOT considered "earned" income like you earned while at your work. It's considered "investment" income and taxed as capital gains. However, if you are active enough and profitable enough it's highly possible the gov't could challenge you on this. Don't know if you'd actually get caught and even if you did it's something that seems like you could fight but I'm no lawyer. What I would do is keep trading and keep collecting unemployment and keep my mouth shut. I don't believe you are breaking any laws. You are just managing your investments, not working.
Quote from IronFist:
Serious question.
Say someone gets laid off and is entitled to collect unemployment. If they are trading during this time and making money, do they have to declare that when they do their bi-weekly unemployment certifications?
