Where the two lines cross, the signal is always overly sensitive and flawed.
So, adding ADXVMA is necessary. Using the lagest, dumbest ADXVMA might work (reduce signal sensitivity at the intersection of two lines).
There seems to be an indicator, which Mladen Rakic said is (probably meant) to solve the US market to make the indicator more sensitive, and the Asian market to make the indicator smoother. Many of our indicators need to incorporate this kind of thinking.
