Thanks for the fast reply mntiwana.

I am not very good with colors but I hope the image below gives a better picture.

1. Red arrow appears when Band2 (Yellow Line) crosses the Lower Trendline (Aqua Dotted Line)

2. Green arrow appears when Band1 (Blue Line) crosses the Upper Trendline (Red Dotted Line)

I have re attached the indicator with the colors as in the image.
