NinjaTrader 8 Bridge —
the connection that holds it all together

Direct JSON bridge between NinjaTrader 8 and the OrderFlowAi dashboard. ML data sync across windows, strategy bridge, and auto rotation that eliminates out-of-memory crashes.

TECHNICAL BACKGROUND

How the NT8 Bridge works

NinjaTrader 8 runs natively on Windows — but complex visualizations and AI analysis need a separate process. The NT8 Bridge crosses this boundary via JSON file communication with automatic rotation.

The NinjaScript indicator writes tick data, DOM levels, and order-flow signals to a JSON file. The dashboard reads them in real time and renders them in the GPU-accelerated heatmap and every other visualization.

Auto rotation prevents JSON files from growing unbounded — a problem that regularly causes OOM crashes in other solutions. With OrderFlowAi, the bridge runs stable for hours.

FAQ
Common questions

Why JSON instead of a direct socket connection?

NinjaScript has limitations with direct socket connections. JSON files are more robust, easier to debug, and enable async processing without blocking the NT8 main process. The data rotation makes the approach production-grade.

What's the bridge latency?

The JSON file updates after every tick — so update rate is bound by NT8 tick rate (typically 4–20ms on ES). The dashboard reads on a configurable interval (default 50ms) for an effective end-to-end latency under 100ms.

Can I use the bridge with my own application?

API access for your own applications is not part of the current plans. If you are interested, write to support@orderflowai.io.

What happens if NT8 crashes or restarts?

The dashboard detects automatically when new data stops arriving and shows a connection status indicator. After NT8 restarts, the bridge reconnects automatically — no manual intervention.
