VWAP BANDS

This nice script combine VWAP band and trend/forecast system based on it
/ode for band take from linear regression script from pine script manual and adopted to VWAP
Trend lines based on VWAP and forecast using Alex grover method with his approval for script

Together it a great too for detection of trend and high and low
for forecast use the trend option
I set length to 100. in daily chart I use 20 . in lower TF I prefer longer 50 or above as it better fit this system
