Trading Signals Buried in Telegram — No Professional Interface, No P&L Tracking

Algo Success was delivering algorithmic trading signals to retail traders through Telegram groups. The problem was fundamental: Telegram is a general-purpose messenger, not a trading tool. Signals got buried under unrelated messages. There was no way to filter by symbol, view historical performance, or track whether past signals had actually returned a profit.

Traders had no P&L dashboard, no real-time charting, and no way to understand which subscription tier would best suit their trading style. The business had no mechanism to differentiate its offering, gate content by plan, or accept recurring subscription payments cleanly. Signal providers and traders were both working around the limitations of a chat app never designed for financial data.

The client needed a purpose-built mobile app that could deliver algorithmic signals with sub-second latency, display live price charts, track P&L across all open and closed positions, and support a tiered subscription model — all in a professional UI that matched the credibility of the algo strategy behind it.

Real-Time Signal Delivery App with WebSockets, P&L Dashboard & Razorpay Subscriptions

Akshara Technologies built Algo Success as a production Flutter app published on both the Google Play Store and Apple App Store. The app establishes a persistent WebSocket connection to the signal backend, streaming live price data and new signals with latency under 200ms — a genuine step change from Telegram's unpredictable delivery timing.

When a new buy or sell signal fires, Firebase Cloud Messaging delivers a push notification instantly, even when the app is backgrounded. The signal card shows entry price, target, stop loss, and a live mini-chart powered by the Charts library. Traders can tap through to a full P&L dashboard showing realised and unrealised gains across their active signals.

Three subscription tiers — each with distinct signal access levels — are gated in the app and billed through Razorpay's subscription API. Plan upgrades are handled in-app with zero friction. The subscription state is verified server-side on every session, so access control is robust even if a user tampers with local storage.
