    How to get script to work with NT7

    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 NT7. 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:

    Its a Trade Volume Index [TVI] indicator

    Code:
    #region Namespaces
    using System;
    #endregion
    
    namespace ScriptCode {
        /// <summary>
        /// Indicator scripts are used for calculating a series of numerical values.
        /// 
        /// 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>
        public partial class MyIndicator : IndicatorScriptBase // NEVER CHANGE THE CLASS NAME
        {
    #region Variables
            // Use for the underlying symbol index on which to calculate the indicator script.
            private int _symbolIndex;
            // Use for the minimum tick size.
            private double _MTV;
    #endregion
    
    #region OnInitialize
            /// <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

    Hello panther6500,

    Thank you for your post and welcome to the NinjaTrader Support Forum!

    This code is not in a format that would be recognized as an indicator in NinjaTrader 7. Do you know what version of NinjaTrader this was developed for? Or what trading platform?
