They may be grade 2 indicators, but to date, they are the only tools I have found to be consistently useful.
As explained, the 7-10 rules seem very simple. 7 to 10 days of higher highs, and higher lows, and you sell any sign of weakness, correct? The reverse is true in bear markets.
If you understand the way I use Bollinger Bands and moving averages, you will see they pretty much reflect the same data. In addition, those who are intimately familiar with thier favorite indicators can probably see it as well.
My problem is not necessarily that the method exists. I just have never seen a single, stand alone method that is anymore then 50% reliable. That is why I like to layer multiple tools together, to weed out false signals.
