Alpha Vantage API: Build a Free Stock Market Dashboard in Python (Real-Time Prices, Charts, Alerts)

Last month, my friend paid $49/month for a stock tracking tool. I built the same thing for free in 45 minutes using Alpha Vantage API. Here's exactly how. Why Alpha Vantage? Most stock APIs either cost money (Bloomberg Terminal: $24,000/year) or require complex authentication. Alpha Vantage gives you: Real-time & historical stock prices (every US stock) Technical indicators (RSI, MACD, Bollinger Bands — 50+ indicators) Forex & crypto prices Fundamental data (earnings, balance sheets, income statements) Free tier : 25 requests/day (enough for a personal dashboard) Step 1: Get Your Free API Key # Sign up at alphavantage.co (takes 10 seconds) # Your key looks like: ABCD1234EFGH5678 export ALPHA_VANTAGE_KEY = "your_key_here" pip install requests pandas matplotlib Step 2: Fetch Real-Time Stock Prices import requests import pandas as pd API_KEY = " your_key_here " def get_stock_price ( symbol ): """ Get current price for any stock ticker.
