I don't think five40 is talking about the same thing as Pair trading as in the above example. QQQQ and QID trade in OPPOSITE directions. The only problem with five40's idea might be on a "doji" day that could stop out on both sides.Seems to be a profitable system overall IMO.
Technically speaking, ure right to point out that those two move inversely to one another. However, considering that the pair is inversely correlated, could you not go long for both instruments instead of initiating the customary long/short trades?
