DOM On Chart
User Guide
Introduction
The DOM On Chart (Depth of Market On Chart) indicator for NinjaTrader 8 is designed to merge real-time Order Book reading (DOM) directly with chart analysis. It displays real-time Bid and Ask volumes, executed trades (Inside Print), and Delta per price level directly on the right side of the chart, allowing traders to perform Order Flow analysis without leaving the chart window.
System Requirements
- NinjaTrader 8 (latest version recommended).
- A data provider that supports tick-level data and market depth
- (e.g., Kinetick, CQG, or Rithmic).
- Windows OS (as NinjaTrader is Windows-based).
- Minimum: 8GB RAM, modern CPU for smooth performance with high-volume instruments.
Installation
- Download the Indicator: Obtain the compiled DLL from your purchase/download link.
- Import into NinjaTrader:
- Open NinjaTrader.
- Go to Tools > Import > NinjaScript Add-On.
- Select the file and follow the prompts.
- Restart NinjaTrader if prompted.
- Verify Installation:
- Open a chart.
- Right-click > Indicators.
- Look for "●⬤【 DOM On Chart】⬤●" under the "FlowMatriX" folder in the indicator list.
- If it doesn't appear, check the NinjaTrader logs for errors (Help > Mail to Platform Support).
Important: After import, DOM On Chart will appear in the "FlowMatriX" category in the Indicators window, not in the main list.
Adding the Indicator to a Chart
