Real-Time Trading Bot Dashboard with SignalR

In the .NET world, SignalR is the cleanest way to push real-time updates from your c# trading bot to a web browser. It handles WebSocket connections, fallbacks, and client management automatically.

Setting Up SignalR Hub

public class TradingHub : Hub\n{\n    public async Task SendPnlUpdate(decimal pnl)\n    {\n        await Clients.All.SendAsync("ReceivePnl", pnl);\n    }\n}

Pushing Bot Events

Inject the IHubContext<TradingHub> into your bot service. Every time an order fills, call hubContext.Clients.All.SendAsync("OrderFill", order). Your dashboard instantly reflects the state without polling in your algorithmic trading with c# .net tutorial.

The JavaScript Client

const connection = new signalR.HubConnectionBuilder().withUrl("/tradinghub").build();\nconnection.on("ReceivePnl", (pnl) => {\n    document.getElementById("pnl").innerText = pnl;\n});\nawait connection.start();

Deployment

Deploy your ASP.NET Core app to the same VPS as your bot. Use NGINX as a reverse proxy with WebSocket support enabled. This gives you a professional-grade monitoring UI for your build trading bot with .net project with minimal extra infrastructure.
