Vortex Bands

A slighty modified version of Better Bollinger Bands. The idea of the experiment was to do a thing like the well-known Vortex Indicator, but an overlay:

Obvious trading rules are:

• go Long when the blue line is above other two
  
• go Short when the orange line is above other two
  
• stop when price crosses the basis line
  

The tool is EXPERIMENTAL. Good luck!
