In simple English
This tool downloads stock market data from a popular financial website directly into your Python scripts. You can pull company financials, news, insider trades, and stock screeners without clicking through web pages by hand. It saves hours of manual copying when you build your own trading models or watchlists. The tool is free to use under an open source licence. You need basic programming skills in Python to run it and make sense of the tables.
What it is
finvizfinance is a Python (a programming language used to write software) library (a collection of pre-written code you can use in your own programs) that acts as a wrapper for the Finviz financial portal. It collects tables of stock prices, insider trading activity, economic calendars, and screener results into pandas (a Python tool for working with tables of data) dataframes.
What it is good for
Solo builders and traders who want to gather stock market data automatically for research, backtesting, or personal dashboards without paying for expensive data feeds.
- Collects stock screeners, fundamentals, and insider trades with simple Python commands.
- Organises downloaded data straight into pandas dataframes for analysis.
- Includes support for proxy servers to prevent your IP address from getting blocked.
- Depends on the structure of an external website, so website redesigns can break the code.
- Requires writing and maintaining Python scripts to get any use out of it.
- Provides no graphical interface or ready-made database storage.
