Quick answer
NinjaTrader does not offer a cloud REST trading API for its desktop platform. Automation runs as NinjaScript (C#) strategies inside NinjaTrader 8, or through the Automated Trading Interface (ATI), which lets external programs send orders to the installed platform via a DLL or OIF text files. For a web API on NinjaTrader-group futures accounts, look at Tradovate.

Three ways to automate NinjaTrader
- NinjaScript: port your strategy to C#; backtest and run it in the platform.
- ATI: keep logic in Python and send orders to NinjaTrader by writing OIF files or calling the DLL.
- Tradovate API: if your futures account can live at Tradovate, use its REST and WebSocket API directly.
Build a NinjaTrader strategy with AlgoGP
AlgoGP does not connect to NinjaTrader natively yet. NinjaTrader connects through a local gateway, socket, FIX or Protobuf stack rather than plain HTTPS, so it runs as a separate process next to your strategy.

Design and backtest in AlgoGP
Describe the strategy to the copilot and backtest it on years of normalized history. The result does not depend on any vendor.

Export the Python project
Every project exports
strategy.py,market_data.py,brokers.pyandlive.py. The strategy only sees bars, cash, positions and orders, never a vendor’s wire format. - 3
Plug in NinjaTrader
Implement the four adapter methods (
account,positions,submit_market_orderand a candle fetcher) with NinjaTrader’s SDK, or keep a built-in platform for paper trading and add NinjaTrader when you go live.
Built-in data sources for the same markets: Yahoo Finance, Alpha Vantage, OANDA, Massive (Polygon.io).
NinjaTrader API: frequently asked questions
Does NinjaTrader have a REST API?
Not for the desktop platform. Use NinjaScript or ATI, or the Tradovate API for a web-native route.
Can I use Python with NinjaTrader?
Yes, indirectly: Python can place orders through ATI (OIF files or DLL) while NinjaTrader is running.
Design and backtest your NinjaTrader strategy first
AlgoGP turns an idea into Python and tests it on years of history before you connect it to NinjaTrader. The exported code keeps the broker behind four small adapter methods.
- AI copilot writes and revises the rules
- Backtests with realistic costs
- Exported Python ready to wire to NinjaTrader
Free plan, no card required.
