Stock Watchy

Stock Watchy is a web application designed to help users monitor their favorite stocks by adding them to a personalized watchlist. The application provides real-time data and news sentiment analysis for each stock, allowing users to stay updated on the latest market trends and news.

Features

• User Authentication: Secure login and signup functionality.
• Personalized Watchlist: Add and manage stocks in your watchlist.
• Real-time Stock Data: Displays up-to-date stock information using TradingView widgets.
• News Sentiment Analysis: Provides sentiment analysis for the latest news articles related to the stocks in your watchlist, including:
  • Title: The title of the news article.
  • URL: The URL link to the news article.
  • Overall Sentiment Score: The sentiment score of the news article.
  • Overall Sentiment Label: The sentiment label (e.g., positive, neutral, negative) of the news article.

APIs and Data

The application features data from various APIs, including:

1. Real-time Stock Data: Integrates TradingView widgets to display live stock data and charts.
2. News Sentiment Analysis: Uses the Alpha Vantage API to fetch news articles and their sentiment scores related to the stocks.
3. Ticker Data: Utilizes a pre-defined list of stock tickers to help users search and add stocks to their watchlist.

API Call Optimization

The application optimizes API calls by caching news data for stocks that is less than one week old. If the cached data is available and not older than one week, it uses the cached data instead of making a new API request. This reduces the number of API calls and improves the application's performance.
