A financial news service needed a way to push real-time market alerts to subscribers — with filtering by asset class, threshold-based notifications, and a self-service subscription management system.
Bot Features
- Real-time alerts: Price movement notifications triggered by webhooks from market data APIs, delivered in under 2 seconds
- User preferences: Subscribers set alert thresholds, choose which assets to track, and set quiet hours — all via the bot's inline keyboard menu
- Mini dashboards: Users request on-demand portfolio snapshots or market summaries directly in chat
- Group management: Premium tier channels with invite link management, subscription expiry, and auto-kick for expired users
- Admin panel: Broadcast messages, view subscriber stats, manage subscriptions — all via Telegram itself
Technical Details
Built with python-telegram-bot (async), a FastAPI webhook server, PostgreSQL for user state, and Redis for rate limiting. The system handles 10,000+ active subscribers with sub-100ms response times.
