Interactive Stock Visualization with Streamlit

📋 Description

This project allows users to visualize the historical stock prices of multiple stocks interactively in real-time using Streamlit and Plotly. By inputting a list of stock tickers (e.g., PETR4.SA, VALE3.SA, ITUB4.SA), the app fetches data from Yahoo Finance and displays an interactive line chart showing the stock prices over time. The application automatically updates every 30 seconds to ensure the displayed data remains current.

🚀 Features

• Input multiple stock tickers and view them simultaneously.

• Interactive graph with Plotly showing the historical closing prices.

• Real-time updates every 30 seconds.

• Display current stock prices in Streamlit's metric cards.

• Option to download the data as a CSV file.
