Past and Present
as my old teacher used to say :
"We come from the past to search for the future.. but we stuck in the present looking on what lie ahead"
So this indicator based on non security MTF (HTF) set to daily
there are two type of bands
first is the present ones (color gray and red)
next is past one (based on 100 candle)
as we can that the price of the past bands and present band try to get equilibrium
once the bands depart from each other -present cross up the past then it will be bullish signal and vice versa when price depart from present band it will tend to fall to the level of our past band
since it based on EMA 100 and organised to detect resistance and support
then it easy to see when price collapse or price rise
so this is theory behind this indicator
you can try different length or different TF for better results
