A single member LLC that has not made the election to be taxed as a corporation is a disregarded entity so you still cannot do an end run around the sec 475 rules like you want to do. I highly recommend you seek local professional assistance for guidance on what you can and cannot do so you don't mess things up going forward. One thing you could have done is done the "day trading" in the ROTH to start with so you really need to get educated on what you are doing vs what you want to do.
