General Dev Environment

[RickJames]

I'm using Ninja Trader 8 and Visual Studio 2022 Pro trying to develop my own volume indicator
I followed the instructions and added NinjaTrader.Core, NinjaTrader.Gui and PresentationCore(4.8.1) to my project references

My Code is just for testing purposes

using NinjaTrader.Gui;
using NinjaTrader.NinjaScript;
using NinjaTrader.NinjaScript.DrawingTools;
using System.Windows.Media;

namespace NinjaTrader.NinjaScript.Indicators
{
public class TestIndicator : NinjaTrader.NinjaScript.Indicator
{
protected override void OnBarUpdate()
{
Draw.Line(this, "TestLine", true, 10, Close[10], 0, Close[0], Brushes.White, DashStyleHelper.Solid, 1);
}
}
}

and I'm getting: CSO0234 The type or namespace name 'Indicator' does not exist in the namespace 'NinjaTrader.NinjaScript' (are you missing an assembly reference?)

Would appreciate any word of wizdom.

Hello RickJames,

Thank you for your post.

There are missing Using declarations, as well as a syntax error in the class declaration.
When you begin developing an indicator, we highly suggest starting with the NinjaScript Wizard, which will generate the minimum necessary code for the script.
For more information, please review the NinjaScript Wizard page of our Help Guide:

• NinjaScript Wizard

The generated code would include the appropriate Using statements and class declaration. You will notice this code wouldn't use NinjaTrader.NinjaScript.Indicator, just Indicator in the class declaration.

public class TestIndicator : Indicator

I also recommend reviewing our Help Guide page that explains how to use Visual Studio with NinjaScript Editor.

• NinjaTrader Help Guide -Visual Studio Debugging

When you use Visual Studio for editing, ensure that you save the file (don't run or build the solution then in Visual Studio), preferably with the NinjaScript editor opened still at the same time, so changes would be auto compiled by NinjaTrader.

If you have any other questions or need further assistance, please let me know.

Hello,

Thank you for your reply.

Please be aware that building the entire indicator in Visual Studio is not supported, as you will ultimately also need to use the NinjaScript Editor.

I am unfortunately not certain which guide you are referring to.
If this is something we have published, please respond with a link to it.

I quickly generated an indicator script from the NinjaScript Wizard, and these are the Using references it generated:

#region Using declarations
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Input;
using System.Windows.Media;
using System.Xml.Serialization;
using NinjaTrader.Cbi;
using NinjaTrader.Gui;
using NinjaTrader.Gui.Chart;
using NinjaTrader.Gui.SuperDom;
using NinjaTrader.Gui.Tools;
using NinjaTrader.Data;
using NinjaTrader.NinjaScript;
using NinjaTrader.Core.FloatingPoint;
using NinjaTrader.NinjaScript.DrawingTools;
#endregion

Please let me know if I may be of any further assistance.
