Gooday ET World! I am establishing myself as Trading as a Business, trading mainly stocks and options, and in the future adding Forex & Futures. To keep it simple, which Entity if any, would provide me with the most benefits as far as Deductions / Protection / Tax Shelter? I have an established Series L.L.C. which is used for other businesses and I am contemplating running my trading business through its own LLC. I have read and have heard previous input of C and S Corps as well. My Goal is an (Independent / Individual) trader and not a company group of traders. Input and experiences are appreciated, Professional Trader Status vs. Non Professional Trader? Thanks in advance! PureProfits
