MTF Market Band with ema colors and volume-based opacity

New indicator I've been playing around with.

Basically, if the candles are above the band, than you should be in a long position (daily) and if your candles are below the band, your should be in a short position...
The width of the band changes based projected highs and lows.
If its transparency is based off volume but I need to rework it somehow :-/
Right now, transparency shows you should close your position.

light green = beginning of bullrun
Yellow is ema strong up

What do you all think?
