If the k-1 you receive is on your name and Social Security# there isn't anything you can do but file Scedule E. Not legally. Not even illegally. If the firm where you trade will allow you to trade a sub-LLC, that's a different story. Then it all depends on your numbers.
are you trying to set up a retirement account because you feel you should have one or are you trying to set up a retirement account that lets you day trade???
