The goal of this project was to develop a stock alert program using Python that calculates the percentage change in a stock's value. The percentage change is determined by comparing yesterday's closing price to the closing price two days ago. If the stock's value increases or decreases by more than 5%, the program will output the three latest news articles about the corresponding company.
The program can be also extended by code for sending e-mail alerts (see the hashed code example at the end of main.py). To automate this program as an e-mail stock alert, you need to host it in the cloud (e.g. pythonanywhere).
First you need to get two own API keys for this project.
Visit https://www.alphavantage.co/support/#api-key. After filling in the form, click on 'Get Free API Key'. Keep your now generated key somewhere save. In main.py pass it either directly as a string to the variable stock_api_key instead of os.environ.get("STOCK_API_KEY") or create an environment variable (e.g. STOCK_API_KEY) with your API key and pass it to stock_api_key like in the code example.
For generating an API key for the variable news_api_key visit https://newsapi.org/register. After you registered for the API key, you'll be forwarded to a new page and the key will be displayed. You'll receive also an e-mail with your API-key. Pass your key to the news_api_key variable like described in the 'stock_api_key' paragraph above.
Customize the global variables STOCK_SYMBOL (in main.py) and COMPANY_NAME (in news_request.py).
The required symbol is the symbol of the equity of your choice. For example: symbol=IBM. You can find the symbol for your equity e.g. here: https://www.tradingview.com/markets/.
Run main.py to obtain the percentage change that your stock increased / decreased and receive eventually the latest news.
