Here's my idea. Create an investment company from your Roth IRA, use it to open another account at your LLC, combining it with your regular trading account. Trade them both simultaneously (just one order for both). Allocate 10% of your daily p/l to the roth and watch it grow tax free. Here's the problem. Attorneys are telling me that there must be seperate orders. One cannot just allocate p/l or stocks for that matter to one's roth. I'm thinking hedge funds must use software that will, say, take one order and divide it among accounts before actual execution. Has anyone any experience with this softwate, or day trading his roth?
