I have in a Ninjatrader indicator the following:

#region Using declarations
using System;
using System.Diagnostics;
using System.Drawing;
using System.Drawing.Drawing2D;
using System.ComponentModel;
using System.Xml.Serialization;
using NinjaTrader.Data;
using NinjaTrader.Gui.Chart;
#endregion

protected override void OnBarUpdate()
        {
Process.Start("C:\test.exe");
            } 

But the test.exe doesn't start when loading the indicator into a chart. The chart doesn't load the indicator at all.. Do I something miss?

Thx!

Hello no111,

This script does not have the Initialize() method in it and likely will not run. This indicator is also not part of the Indicator namespace and would not have access to methods for the indicator.

I cannot comment on using Process.Start() as this is not supported by NinjaTrader Support to use.

The other code:

    protected override void Initialize()
        {
            Add(new Plot(Color.DarkGray, "Midline"));
            Add(new Plot(Color.DarkGray,     "Upper"));
            Add(new Plot(Color.DarkGray,     "Lower"));

            diff                = new DataSeries(this);

            Overlay                = true;
            
            
        }

        /// <summary>
        /// Called on each bar update event (incoming tick).
        /// </summary>
        protected override void OnBarUpdate()
        {
            diff.Set(High[0] - Low[0]);

            double middle    = SMA(Typical, Period)[0];
            double offset    = SMA(diff, Period)[0] * offsetMultiplier;

            double upper    = middle + offset;
            double lower    = middle - offset;

            Midline.Set(middle);
            Upper.Set(upper);
            Lower.Set(lower);
             
            //    if ( Close[0] != Close[1])
            //{
            //}

            Process.Start("C:\test.exe");
            } 

Hmm okay, do you know a workaround to load this exe file? or word file?

Hello no111,

Starting a process outside of NinjaTrader is not supported by NinjaTrader to do.

However, this thread will remain open for any community members that would like to assist.


However, you mention that the indicator will load on a chart.

Are you getting error messages in the Log tab of the Control Center?

If so, these may have stopped the script. What do these errors say?

If you add a print to the first line of OnBarUpdate() do you see the print appear in the output window?
