I'll take QQQQ over QLD or QID anyday. The volume is huge and the spread is razor thin so you never have to worry about crap fills.
guys... whats the point of qqqq's when you can trade NQ or NDX? (unless 1 NQ is still too big for you)
Ooooh! Big bad bully trader telling us what to trade. Swing trading QLD works just fine for me, thanks. Good trading to you.
hheheh seriously, though it is a conundrum. If you can daytrade qqqq's, you are likely by definition well enough capitalized to trade 1 NQ. For swing trades, I guess the smaller leverage on the QQQQ makes sense ... for anywhere under 800 shares.
