Yeah, I use it. Pure mechanical. Turns capital 4 to 6 times per year. Suggest strict position size. Such as 1%/3 ATR. That in turn would imply some diversification as a result. Not all will work out, but you're essentially "invested" in the best (on paper) stocks in terms of both elasped earnings and elapsed relative strength. Exit when RS, as published in Investors Business Daily, drops by 5 points or hits your MENTAL stop. Whichever comes first.
