Stock Market Data Visualizer

Author: Charles Eleri

Overview

This is a Python-based Stock Market Data Visualizer that fetches real-time stock data from the Alpha Vantage API, processes it using Pandas, and displays an interactive graph with Matplotlib. This version is designed for command-line execution, removing the dependency on a GUI (Tkinter).

Features

• Fetch stock market data from Alpha Vantage API
• Visualize closing prices over time using Matplotlib
• Simple command-line interface for easy stock symbol input
• Data processing with Pandas for better insights

Installation

Prerequisites

Ensure you have Python installed (>=3.7). Then, install the required dependencies:

pip install requests pandas matplotlib

How to Use

1. Get an API Key from Alpha Vantage.
2. Insert your API Key into the script (already pre-configured):

   API_KEY = "21YYWNHZ2DFIUIPX"  # Replace with your Alpha Vantage API Key if needed

3. Run the script in the command line:

   python stock_visualizer.py

4. Enter a stock symbol (e.g., AAPL, GOOGL) when prompted.
5. View the stock price trend in the generated chart.

Example Output

• The program prompts you to enter a stock symbol.
• The script fetches and processes the stock data.
• A Matplotlib chart displays the stock's closing price trend.

API Key Insertion

To use this tool with your personal Alpha Vantage API Key, update this section in fetch_stock_data():

API_KEY = "your_actual_api_key_here"  # Replace with your Alpha Vantage API Key

Future Enhancements

• Add support for multiple stock symbols in one chart
• Implement moving average indicators
• Save fetched data as CSV for further analysis
