Set out entry signals, exits, position sizing and session rules. Generate a NinjaTrader strategy with configurable inputs you can review and test.
AI coding agent for NinjaTrader 8
Build NinjaTrader strategies and indicators with Xen AI
Describe your trading rules in plain English and develop NinjaScript C# for NinjaTrader 8. Xen helps you plan the work, create editable source and improve it through focused revisions.
Build with Xen
From an idea to a project you can test
Create custom indicators
Describe the calculations, plots, markers and alerts you need. Start with a clear visual specification and refine the indicator on your charts.
Plan larger projects
Prompt Builder helps clarify missing decisions. A staged Build Plan breaks interacting features into smaller changes you can test as you go.
Improve existing NinjaScript
Supply your complete current source to add a feature, explain unfamiliar code or repair a fault while retaining the context of the project.
Check and repair build errors
Run the server-side Build Check to identify compiler issues. Review the repair, then compile in your own NinjaTrader installation to confirm the result.
Convert source from another platform
Adapt complete Pine Script or MetaTrader source to NinjaTrader 8. Review any differences in order handling, calculations and platform behaviour before testing.
Your workflow
Build, check and refine in stages
Describe the behaviour
Choose Strategy or Indicator and explain the rules, inputs and expected output.
Build a focused version
Review the generated NinjaScript and compare it with your original requirements.
Import and compile
After a successful Build Check, download an Add-On ZIP or the editable .cs source. Compile it in NinjaTrader.
Test and refine
Use charts, Strategy Analyzer and simulation. Bring specific observations back to Xen for the next revision.
Learn from testing
Make more of your Strategy Analyzer results
Run the backtest in NinjaTrader, then use Xen to review an exported Strategy Analyzer Summary CSV. You can include a Trades CSV for a closer look at individual outcomes. This analysis works independently of the source project and can review a strategy that was not created with Xen.

Working with Xen for NinjaTrader
Do I need to know C#?
You can describe the initial tool in plain English. Understanding your trading rules and reviewing the generated source will help you assess the result.
Does a successful Build Check mean the strategy is ready?
It confirms the checks performed by the server. Compile in NinjaTrader and test platform behaviour, order handling and risk controls in simulation before live use.
Does Xen place trades?
Xen is a development workspace and does not connect to your trading account. Any generated strategy runs only after you install and enable it in NinjaTrader.
Review and test every version. Generated code can contain errors. Compile in NinjaTrader 8, check the logic and test with historical data and a demo or simulation environment before considering live use. Historical results do not guarantee future performance.
