I have a script I found online of an indicator I have been looking for. Unfortunately I have no background in coding and not exactly sure on how I can import this text into a working indicator for . I would appreciate any guidance on importing this to work with NT7. I have the copy of the script as it was presented on the webpage:
Code

/// This script can be used in several ways:
/// (1) It can be used on a chart.
/// (2) It can be used from another script.
/// (3) It can be used as a script column in a watchlist.

/// <summary>
/// This function accepts the user parameters for the script and is called when a new indicator instance is created.
/// One of the parameters accepted by it must be that of a symbol or another script that is
/// based on a symbol (drawing, indicator, pattern or signal). This symbol will be used as the underlying symbol for the indicator.

/// (1) name: The exact parameter name.
