Quantower Orderflow Bridge: Install the DLL and Connect

The Quantower bridge is a compiled Quantower indicator. It forwards the trades and depth your Quantower connection already receives to Senzoukria on the same Windows PC, through 127.0.0.1:7273. Extract the DLL into Settings\Scripts\Indicators, restart Quantower, add the indicator to one chart and choose Quantower Bridge in Senzoukria. No .NET SDK is needed.

What the bridge does

The bridge runs inside Quantower, on the symbol of the chart it is attached to. It sends Senzoukria the current session’s trade history, then live trades and order-book updates. The connection stays on your machine: the server listens on 127.0.0.1:7273, which other computers cannot reach.

It forwards what your Quantower connection is entitled to receive; exchange fees and provider terms still apply. Footprint delta needs the aggressor side of each trade. When a provider does not supply it, history trades are classified with the tick rule, which is an estimate. Prefer a connection that reports the aggressor side.

Requirements

  • Windows with Quantower installed. The current DLL is built against Quantower 1.146.18 (net10.0); update Quantower first if yours is older.
  • A Quantower connection that streams tick data for your futures contract. A tick chart of that contract should update in Quantower itself.
  • Senzoukria installed on the same PC — see the download page.
  • No Visual Studio and no .NET SDK: the DLL is already compiled.

Download the bridge

Built on 2026-09-14 against Quantower 1.146.18. SHA-256 of the DLL: 56f6d58f48c04d88577419a944ff5528a29a6dd265b70e11c964d7e194672d25. To compare it with your download, run in PowerShell:

Get-FileHash "$env:USERPROFILE\Downloads\QuantowerOrderflowBridge.dll"

Find your Quantower folder

The default installation folder is C:\Quantower. It contains the Settings and TradingPlatform folders. If Quantower is installed elsewhere, right-click its shortcut → Open file location. Explorer opens a folder such as TradingPlatform\v1.146.18; go up two levels to reach the folder that holds Settings.

The bridge belongs in its own subfolder: C:\Quantower\Settings\Scripts\Indicators\QuantowerOrderflowBridge\

Not under TradingPlatform\v…\bin. Quantower installs each version in a new TradingPlatform\v… folder and later removes the old one, so an indicator placed there disappears after an update. The Settings folder is kept.

Install the DLL, step by step

  1. Close Quantower completely. In Task Manager, no Quantower process (Starter.exe) should remain. Quantower reads custom indicators when it starts.
  2. Remove older copies. Delete any QuantowerOrderflowBridge.cs or older QuantowerOrderflowBridge.dll left in Settings\Scripts or in TradingPlatform\v…\bin\Scripts\Indicators. A leftover file can hide the indicator or load an old version.
  3. Extract the ZIP. If its Properties show an Unblock checkbox, tick it and click OK. Then right-click the ZIP → Extract All…, set the destination to C:\Quantower\Settings\Scripts\Indicators\QuantowerOrderflowBridge\ and click Extract.
  4. Check the result. The folder must contain QuantowerOrderflowBridge.dll directly, not a second QuantowerOrderflowBridge folder. With the DLL alone, create that folder yourself and copy the DLL into it.

The same extraction in PowerShell, with the ZIP in your Downloads folder and Quantower closed:

Expand-Archive "$env:USERPROFILE\Downloads\QuantowerOrderflowBridge.zip" -DestinationPath "C:\Quantower\Settings\Scripts\Indicators\QuantowerOrderflowBridge" -Force

Add the indicator to one chart

  1. Start Quantower, connect as usual and open a Chart of the futures contract you want in Senzoukria, for example MNQ or ES.
  2. Open the chart’s Indicators list → Custom → QuantowerOrderflowBridge, and add it.
  3. Keep the defaults: Port 7273 and History slice (min) 30.
  4. Add it to one chart only. Only one copy can open the port.

The chart timeframe does not matter: the bridge requests tick history for the symbol itself. To change contract, move the indicator to a chart of the new contract.

Connect Senzoukria

  1. Open Senzoukria and choose Quantower Bridge as the data source.
  2. Wait for the history. The bridge first sends the trades of the current CME session, counted from 22:00 UTC, then switches to live data. On a very active contract such as MNQ, loading can take several minutes; the bridge waits up to five minutes for Quantower to return the history.
  3. Live trades and depth updates follow, with a heartbeat every five seconds.

The history is captured when the indicator starts. If you connect Senzoukria long after adding the indicator, or reconnect later, remove and re-add the indicator first so the history reaches the current time.

Check that it works

  • In Quantower’s Event log, look for QuantowerOrderflowBridge v3: listening on 127.0.0.1:7273, then a tick history line with the number of trades loaded.
  • In PowerShell, this command returns one line while the indicator is running:
Get-NetTCPConnection -LocalPort 7273 -State Listen

In Senzoukria, the footprint fills with the session history, then updates live.

Troubleshooting

Symptoms and what to check first
SymptomWhat to check
QuantowerOrderflowBridge is not under CustomThe DLL is in Settings\Scripts\Indicators\QuantowerOrderflowBridge\, not directly in Indicators and not under TradingPlatform. Quantower was fully closed and restarted. Older .cs or .dll copies are removed. Quantower is up to date.
“start failed” in the event log, or Senzoukria cannot connectThe indicator is on two charts, a second Quantower is running, or another program uses port 7273. Keep a single copy and check the port with the PowerShell command above.
Connected, but no historyWait up to five minutes. Then open a tick chart of the same contract in Quantower: if the provider returns no tick history there, the bridge has nothing to send.
History covers only the last hours on MNQ or NQProviders cap the ticks returned per request. Lower History slice (min) to 15, then remove and re-add the indicator.
Gap between the history and live dataThe history was captured when the indicator started. Remove and re-add the indicator, then connect Senzoukria right after.
Delta looks wrongCheck that your connection reports the aggressor side; without it, sides are estimated.
Senzoukria reports a bridge driftThe history received differs from the total the bridge announced. Reconnect; if it persists, reinstall the DLL from this page.
Stopped working after a Quantower updateDownload the current DLL from this page and replace the file, with Quantower closed.

Update or remove the bridge

To update, close Quantower, replace QuantowerOrderflowBridge.dll in the same folder with the version from this page, then start Quantower. To remove it, close Quantower and delete the QuantowerOrderflowBridge folder.

Senzoukria reads one bridge at a time: NinjaTrader uses port 7272 and Quantower 7273. The NinjaTrader bridge steps are on the download page; a direct connection is covered in the Rithmic guide.

Build it yourself (optional)

The source file is the one the DLL is built from. To compile it, install the .NET 10 SDK and create a class-library project targeting net10.0 that references TradingPlatform.BusinessLayer.dll from your TradingPlatform\v…\bin folder. Run dotnet build -c Release, then install the resulting DLL as described above.

Frequently asked questions

Do I need Visual Studio or the .NET SDK?
No. The ZIP contains a compiled DLL. Only building the bridge from its source code requires the .NET 10 SDK.
Where exactly does the Quantower bridge DLL go?
In your Quantower folder, under Settings\Scripts\Indicators\QuantowerOrderflowBridge\. With a default installation the file is C:\Quantower\Settings\Scripts\Indicators\QuantowerOrderflowBridge\QuantowerOrderflowBridge.dll. Do not use the TradingPlatform folder: Quantower replaces it on updates.
Can I add the bridge to several charts?
No. It opens one local port, 7273. Add it to a single chart of the contract you want in Senzoukria; a second copy cannot start its server.
Does the bridge place orders or read my Quantower login?
No. It only sends market data from Quantower to 127.0.0.1:7273 on your PC. It has no order function and does not read login details.
Does the Quantower bridge work on macOS or Linux?
The bridge is built for Quantower on Windows. On macOS and Linux, Senzoukria connects through a direct Rithmic login or the crypto feeds.
