Cumulative Net Volume

This indicator calculate the Cumulative Net Volume (volume in versus volume out) as seen in red and green cross
I normalize it to be as price indicator -then using color setting it easy to see when volume influx is positive compare to negative period
next step -I add rsi and Bollinger to highlight the area where volume is going up or down with the best period by rsi and Bollinger (green red)

it easy indicator for starter to see where the best buy or sell point
have fun
