Aren't there some strange tax consequences for trading in and out of MLP's like that? Is your tax liability a prorated portion of the dividend based on how many days you owned it during the quarter regardless of whether you actually received the dividend?
Don't hold an MLP in an IRA. Do some research on your own....just a little googling will tell you the potential tax consequences. Further, if you're not holding an MLP in a taxable account you lose the tax benefits when you sell it.
