Austin, don't you adjust your position size for the higher volatility? I don't understand why that would be your sole reason for preferring TF. Maybe you could argue that the patterns are cleaner (I don't know if they are), but there has to be some reason other than higher vol.
I listen to most of Covel's podcasts, and in Nov2012 he spoke to Tom Basso. I think it was near the end of the interview when Basso spoke about the different ways he controls risk. One thing he does is look at vol as a percent of equity.
the challenge with low vol = low range is, price moves plenty far enough to take out stops on the risk side but does not move far enough for favorable reward. A 6-point range means price churned sideways thru most of that, a 12pt range usually means price churned thru 4pts on the low end and 4pts again on the high end. It forces you to be pinpoint precise on the one or maybe two intraday moves in the middle. Not much opportunity to be right enough to prevail overall.
You take one trade and get stopped out for -1.5pts. Take another trade and scratch, another trade -1.5pts and a fourth trade goes +4 points in favor. What did you accomplish? Not much. These conditions won't last forever, but they are here for now.
ultra-low volatility and no-range sessions are why traders are just treading water or making sloooow progress for now. In the futures world, there are few day-trade alternatives to turn towards. Used to be CL was always a monster. That died from what it was. Now it's pretty much the Russell unless you want to get hammered around in gold, natural gas, etc.
on the other hand, if you adopt a swing-trade mentality, then you can trade anything. whatever futures markets TST offers are fair game. Just mind the open - close - reopen sequences and hold overnights. Matter of fact, if I did a combo again, that's pretty much what my approach would be.
