It seems to me that a currency strength indicator like KG_RS_Group (I myself use Luku's MultiCurrencyStrength) would be much more "picky" and precise, if TMA (or any other) slope of strength will be calculated. For example, luku's indie uses RSI calculations as kang_gun's, so I'll use it (marked entries with red and green rectangles and sorry about the image size

Here we can see, if first slope is >>0, the second is <<0, a clean trend can be catched, and low slope readings will prevent us from entering in ranging or flat markets..
What do you think of this kind of approach?
