This tutorial shows you how to build a real-time stock/crypto price alert system using a simple Python script powered by yfinance and SMTP email automation—all running locally on your own machine or on a server/cloud service. If a chosen stock falls below a certain price threshold, the script will send an email directly to an address you choose.
But this script is really just a starting point. You can easily modify it to send alerts based on major price movements, or even trigger notifications when a technical indicator hits a key level or threshold.
I walk through the setup, environment configuration, and core Python code that checks live stock prices and sends you an instant email alert when your target threshold is hit. This is perfect for anyone trading or investing who wants to stay on top of price dips even when stepping aside from watching the market.
