"Regularly" could mean as low as one order every couple of months, not just looking for day traders.

Actual financial markets: Any type of currency or security (stocks, derivatives, etc) trading. I am asking if manage your portfolio yourself, not if you own stocks or part of a fund that is managed by someone else.

Sports Betting: Any league of any kind provided you could conceivably get an edge in by having a better grasp of publicly available data. I'm not asking about types of gambling not relying on that.
