Challenge
There was no single dashboard integrating multiple exchanges and allowing strategy automation through TradingView alerts.
Solution
We built a NestJS service listening to TradingView webhooks, validated by IP whitelist, encrypting API keys (32-char encryption), executing trades on 4 exchanges. Angular frontend with real-time WebSocket updates.
Results
The manager trades 24/7 across 4 exchanges with <200ms latency on trade execution. P&L tracking, stop-loss, take-profit fully automated.
