“Bridge: connecting to NinjaTrader on 127.0.0.1:7272…” never goes live

What you see

With “NinjaTrader” chosen as the chart data source (hint: “Local bridge — NT8 chart must be running”), the banner stays on “Bridge: connecting to NinjaTrader on 127.0.0.1:7272…”. If the link was up and closed, it reads “Bridge dropped. Reconnecting in {n}s…” and the app retries on its own.

Why it happens

The bridge is an indicator, OrderflowBridge.cs, that runs inside NinjaTrader 8 and opens a listener on 127.0.0.1. Senzoukria connects to it; it never starts NinjaTrader itself. If NinjaTrader is closed, the indicator failed to compile, it is not added to a chart, or its Port property differs from the port Senzoukria uses, there is nothing to connect to. Closing NinjaTrader closes the bridge with it.

How to fix it

• Start NinjaTrader 8 and open a chart of the instrument you want.
• Check that OrderflowBridge.cs sits in Documents\NinjaTrader 8\bin\Custom\Indicators and compiles with 0 errors (NinjaScript Editor, F5).
• Add the indicator “OrderflowBridge” to the chart. NinjaTrader’s Output window should print “OrderflowBridge: listening on 127.0.0.1:7272”.
• Keep the indicator’s Port at 7272, the port Senzoukria connects to for NinjaTrader.
• In Senzoukria, pick NinjaTrader in the Chart data source selector. The banner moves to “Replaying history: …”, then the status bar shows LIVE.

What it is not

• Not a credentials problem: the bridge needs no broker login in Senzoukria.
• Not an internet problem: the connection stays on this machine (loopback).
• Not available on macOS or Linux: the bridge options are marked “Windows only”.

When to contact support

Still stuck after these checks? Use Menu → Report a problem, or post on the Senzoukria Discord. Include the last lines of NinjaTrader’s Output window and say whether the “listening on” line appeared.
