How to Customize the DOM in NinjaTrader

Opening DOM Properties

On any NinjaTrader DOM window:

1. Right-click inside the DOM.
2. Choose Properties.

Every setting you care about is in this window. If you don’t even know what the DOM is showing yet, read: DOM Trading Basics.

Adjusting the Columns

Most traders modify the column layout so it stops looking like a wall of numbers.

• Bid Volume
• Ask Volume
• Last Traded (prints)
• Price
• Position and P/L columns

You can reorder them by dragging the column headers.

Changing Colors

Key color settings you’ll want to adjust:

• Ask/Bid background
• Last traded price highlight
• Working order colors
• Filled order colors

Keep the colors clean and readable — same logic as Simple Chart Layout.

Font Size and Row Height

If the DOM looks like ants crawling across your screen, increase:

• Font Size
• Row Height

Order Display Settings

These settings matter for live trading:

• Show Marker – shows working orders directly on the DOM
• Show Quantity – displays contract size—don’t trade blind
• Show Cancel Buttons – adds easy “X” to kill orders
• Show Price Line – highlights the inside bid/ask

Submitting Orders From the DOM

DOM settings don’t matter if you don’t know how to execute properly. Review:

• NinjaTrader Order Entry
• Execution vs Idea

Saving DOM Layouts With a Workspace

Once your DOM is set the way you want:

1. Open Control Center.
2. Workspaces → Save Workspace.

This ensures your columns and colors stay the same every time. If not, fix your layout using: NinjaTrader Workspaces.
