i like thinking outside the box....brings in fresh

i like thinking outside the box....brings in fresh ideas imo.......but im not to savy at the behind the scenes stuff......that being said if etrade and cor were in it togeather......(and if any of what im about to say is even possible) i dont think cor used etrade as a broker to short with margin cuz etrade would just put a call on cor......i dont think etrade need cor to short because etrade can execute their on trades.......so i wonder if etrade used cor to clear a (naked note)......this statement is strictly hypothetical.....and again i dont even know if any of that is possible.....lol...amo glta
