TradingView RealTime

GoMarketWatch is a real-time market data tracking application built with Go, utilizing the power of concurrent websockets and scheduled tasks. It uses the Gin framework for handling HTTP requests, and integrates tradingview's API to fetch and update financial symbol data in real time.

Features

  • Real-Time Data Updates: Utilizes websockets to receive updates about financial symbols from TradingView.
  • Concurrent Handling: Manages multiple symbol data concurrently with robust synchronization using mutexes to ensure data consistency.
  • Automated Cleanup: Scheduled tasks identify and remove inactive symbols that haven't been requested in over 30 seconds to maintain efficiency.
