The Vortex indicator is based on two trend lines that indicate an uptrend (VI+) or a downtrend (VI-) in the current market. This can be used to determine trend reversals or confirmations of current trends and directions. The number of periods is usually between 10 and 25. This indicator has 14 periods as its default value. You can adjust this value in the settings...
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!
