I still lie awake at night, wondering how your friends made money from your famous 'the dow will never break the March low's' call... hmm... that was like... 4000 points higher than were we are now?
ATR is perfectly fine if you have no other way of determining the probabilities of your trade. If the odds of your trade succeeding are nothing more than a result of extensive backtesting, instead of an evaluation of the market after you enter the trade, than ATR might be just what you need. If you are however looking to understand the market and learn to act on what you see - instead of letting yourself get stopped out for no reason other than because your automatically calculated formula tells you to place the stop there - then, and only then, will you truly 'manage' risk.
Managing risk is something which is done NOT ONLY before the trade is entered. It is a dynamic process, which need continuous evaluation as long as the market is in a state of flux.
I'm pretty sure I know the answer to this question, but I'll ask anyway: do the TT people trade less size and have wider stops (in terms of absolute points) then 6 months ago? If the answer is yes, I invite them all to think for themselves for a minute :idea: and reflect whether it is really necessary to put more money at risk, just because the market moves a greater range in the same period of time.
Verbal abuse? Fact is what you are telling is what every book for beginners says. That you should change your stop size and adopt accordingly position size to volatility blah blah. Unfortunately that's not the right path to teach a person about risk. By all means, use that approach if you have nothing better at hand. It definitely beats guessing. But it's far from optimal.
I ask again, if you could win $200 with buying a lottery ticket and you had the choice between one of $5 and one of $10 (odds of winning the same on each ticket), which one would you buy? Until you get that, there's no point in trying to explain risk "management".
