Hi guys, I am interested in finding out more about trading the QQQQ. I tried googling for the relevant details and still could not find some of the answers i need. 1)I understand that it is a ETF, so is this bound under the $25 k rule for day trading ? (Not that I plan to do this). 2) Is there a minimum bid size of say 100 shares? 3) If i buy say 10 shares, does it cost me 10x $41.397 = $413.97? 4) Then do i win / lose $10 for every dollar it drops assuming i buy 10 shares? Thank you for your patience.
