This third file confirms a recurrence of CS0246 compiler errors in VWAP_Pro.cs, specifically related to undefined types like ModeType and AnchorModeType.

🔍 CS0246 - "The type or namespace name 'X' could not be found" Line Column Missing Type 371 28 ModeType 371 43 AnchorModeType 391 39 ModeType 391 54 AnchorModeType 376 51 ModeType ✅ How to Fix It 🔧 1. Define Missing Enums (Recommended Fix)

It seems that ModeType and AnchorModeType are custom enums that were expected to exist in the code but were never declared.

Create a separate file or include this in the same VWAP_Pro.cs file near the top:

public enum ModeType { Standard, Aggressive, Conservative }

public enum AnchorModeType { SessionStart, FixedTime, Custom }

You’ll need to customize the enum values (Standard, Aggressive, etc.) to match your strategy logic. These names are placeholders based on typical VWAP settings.

🔧 2. OR Add Missing using Directives

If these types exist in another NinjaTrader script or add-on you've imported before, ensure you include the right namespace:

using NinjaTrader.NinjaScript.AddOns.MyVWAPEnums; // Example

But since these errors suggest the types are completely undefined, it's much more likely they are simply not declared anywhere.

🔧 3. Verify File Inclusion in NinjaTrader

If these enums are defined in another file (e.g., VWAPTypes.cs), make sure:

It's saved in the same directory as VWAP_Pro.cs

It's added to the NinjaScript Editor, not just sitting in the file system

You can add it using:

Tools > NinjaScript Editor > Right-click > Add > Existing Item...

🧼 Suggested Organization

If these enums are used across multiple indicators/strategies, you should centralize them:

VWAP_Enums.cs

namespace NinjaTrader.NinjaScript.VWAP { public enum ModeType { Standard, Aggressive, Conservative }

public enum AnchorModeType
{
    SessionStart,
    FixedTime,
    Custom
}

}

Then use:

using NinjaTrader.NinjaScript.VWAP;

These are occurring in VWAP_Pro.cs, mainly on lines 132–134:

Line Error Message (Truncated) 132 Argument 2: cannot convert from 'int' to 'NinjaTrader.Gui.Tools.SimpleFont' 132 Argument 3: cannot convert from 'NinjaTrader.Gui.Tools.SimpleFont' to 'System.Windows.Media.Brush' 133 Same as above 134 Same as above 🔧 Interpretation:

It looks like a method (likely a drawing method like Draw.Text() or Draw.TextFixed()) is being called with the wrong argument types — specifically:

An int is being passed where a SimpleFont is expected.

A SimpleFont is being passed where a Brush is expected.

This suggests that arguments are out of order or misassigned.

✅ Proper Fix

Let’s consider the proper usage of Draw.Text() in NinjaTrader 8:

Draw.Text(NinjaScriptBase owner, string tag, bool isAutoScale, string text, int barsAgo, double y, Brush textBrush, SimpleFont font, TextAlignment alignment, Brush outlineBrush, int outlineWidth);

Or for simpler usage:

Draw.Text(this, "tag1", "Hello", 0, Close[0], Brushes.White);

Your issue likely looks like this:

Draw.Text(this, "tag1", true, "Label", 0, 100, 12, someFont, ...);

Where 12 (int) is mistakenly passed as a font or brush, causing the error.

🔧 Corrected Example:

Assuming you want to draw text with a specific font and color:

SimpleFont font = new SimpleFont("Arial", 12); Draw.Text(this, "tag1", true, "VWAP Label", 0, Close[0], Brushes.White, font, TextAlignment.Center, Brushes.Black, 1);

Brushes.White → text color

font → SimpleFont object

TextAlignment.Center → alignment

Brushes.Black → outline brush

1 → outline width

✅ Steps to Fix:

Replace the integer (e.g., 12) with a SimpleFont:

new SimpleFont("Arial", 12)

Ensure arguments are in the correct order: Double-check the method signature from the NinjaTrader 8 Help Guide .

Use Brushes for colors, not fonts.

Summary of Errors: Line Column Missing Type 403 39 ModeType 403 54 AnchorModeType 408 63 ModeType 408 78 AnchorModeType 367 28 ModeType ✅ Fixes:

These types — ModeType and AnchorModeType — are not recognized. Here are the likely causes and solutions:

🔍 1. Missing using Directive

These types might be defined in a different namespace. If they are from a custom or NinjaTrader add-on:

Fix: Add the appropriate using statement at the top of your file.

Example:

using NinjaTrader.NinjaScript.AddOns.VWAP;

Adjust according to where ModeType and AnchorModeType are defined.

🔍 2. Missing Class Definitions

If they are not in any existing libraries, they might be custom enum types that should be defined in your project but are missing.

Fix: Add enum declarations like these (if applicable):

public enum ModeType { Standard, Aggressive, Conservative }

public enum AnchorModeType { SessionStart, FixedTime, Custom }

Only do this if you know what the enum values should be. These names are placeholders — you should match them with how your indicator/strategy is designed.
