I firmly disagree. Maybe for the 1 lot trader who needs a huge range in order to capture 4 points and hence $200, then this might be the case (ie. they are jumping around looking for anything that moves). For the traders trading size, 20+ contracts, who have experience trading both a tight range or trending days, even making 2 or 3 points per day is a huge payoff. Learning to trade both the ES and CL for example requires very different strategies and trying to be a trader that is profitable on both is twice as hard than trying to figure out how to be profitable on initially just one.
