Trade3Dx IBKR Bridge 0.1.2-beta — Windows x64
Signed publisher: LVL N CAPITAL LLC

Extract the entire ZIP into a writable folder; keep every file and Assets together.
Run Trade3Dx.IbkrBridge.exe. The .NET runtime is included.

Setup guide: https://trade3dx.com/ibkr-setup/
Trade3Dx installer: https://trade3dx.com/downloads/

Install the official IBKR TWS API separately and accept its terms:
https://interactivebrokers.github.io/
If CSharpAPI.dll is not built, install the .NET 8 SDK and run:
dotnet build "C:\TWS API\source\CSharpClient\client\CSharpAPI.csproj" -c Release -f net8.0
The bridge searches standard API build folders. You can also place the built
CSharpAPI.dll beside the bridge executable. The IBKR API is not included here.

Enable ActiveX and Socket Clients in TWS API Settings. Allow 127.0.0.1.
Read-Only API can remain enabled. Use a unique client ID (default 73).
Default ports: TWS Live 7496, TWS Paper 7497; Gateway Live 4001, Paper 4002.
Choose the contract and subscriptions in the bridge. Start it, then connect
Trade3Dx. Run one IBKR or NinjaTrader bridge at a time.

Market data requires your own IBKR entitlements. API Smart Depth can differ
from a TWS Level 2 view. Recorded heatmap carry-forward is historical data;
it does not establish that a level still exists in the current order book.
After a TWS/Gateway disconnect, restore the session and restart the bridge.
