polygon-fetcher

This program runs a static file server that serves HTML reports for stocks.

Usage

The server listens to port 80 and serves HTML reports from output_dir/html folder. To request a report for AAPL, run the program and go to localhost/AAPL.html in a broswer. If the report does not exist, the program will pull data from polygon.io using REST APIs and generate a HTML report. The data will be stored in output_dir/json in JSON format, while the report will be stored in output_dir/html as HTML.
