I play that way, but I just use the same account.  I have 10,000 shares (CWSFF, American side) to hold for the long haul.  But, with the steep drop this morning, I was able to buy 650 shares cheaply (91 cents US).  Sold them all later at $1.01.  Still I have my original 10,000 shares for the long haul, but $60+ better off for the day.  Just seemed like easy money.

YOUR CALLING ME A ROOKIE  I WOULD BE EMBARRASSED  PAPI
