the yellow dots are the wkly lows, the Blue dots are the wkly Hi prices.
In a falling market it would look as if the yellow moves first and vice versa. Not sure, but something to look out for?
I tend to notice the compression points when the Blue and Yellow (Hi and Lo) prices points compress, it seems to be a spring of sorts,
kinda like when Bollinger Bands compress.
just my 2 cts worth, what say U, R?
