Profitable Vortex Indicator Scanner

Introduction
The Vortex Indicator is a technical indicator invented by Etienne Botes and Douglas Siepman (Technical Analysis of Stocks & Commodities, V.28:1 (January, 2010): "The Vortex Indicator") to identify the start of a new trend or the continuation of an existing trend within financial markets.

It is composed of two lines, +VI and -VI. +VI represents up trending momentum and -VI represents down trending momentum.

The most basic strategy is to use the crossovers as trade signals:

• when +VI crosses above -VI, go Long
  
• when -VI crosses above +VI, go Short
  
• Exit when a crossover occurs in the opposite direction
  

What is this tool?
This tool is a performance scanner that uses a decision tree-based algorithm under the hood to find the most profitable period's setting for the indicator. It analyzes the range of periods between 2 to 100 and backtests the Vortex Indicator for each period using the strategy mentioned above across the entire history of an instrument.

Settings
Net Profit line is optional and can be hidden through settings.

Alerts
It has an alert that notifies when a more profitable period was detected.

NOTE: It does not change what has already been plotted.

Good luck!
