Better to just dive right in, IMO. No record keeping requirements. Preferential tax treatment. S/R behavior that is not obvious looking at QQQQ. Clean T&S. No execution games. Leverage. Rarely any slippage.
If you can chart two issues together, look at NQ and QQQQon say, a one minute chart. I think you'll see a difference. My apologies if I am wrong, haven't done that for years, switched to NQ maybe 5 years ago.
