Vortex Indicator on the Charts
According to Investopedia: The Vortex Indicator was first developed by Etienne Botes and Douglas Siepman who introduced the concept in a 2009 edition of "Technical Analysis of Stocks & Commodities". The vortex indicator is based on two trendlines: VI+ and VI-.
Key concepts:
  • An uptrend or buy signal occurs when VI+ is below VI- and then crosses above VI- to take the top position among the trendlines.
  • A downtrend or sell signal occurs when VI- is below VI+ and crosses above VI+ to take the top position among the trendlines.
  • Overall, the trendline in the top position generally dictates whether the security is in an uptrend or downtrend.
The parameters of the Vortex indicator can be changed by locating and opening the Javascript Code under Data Building Procedure -> Procedure Loop under "Vortex Indicator" Product Definition.
