This is the web app that I use to monitor my investments. It reads my diary from data_entry.json, searches for the economic data with the yfinance Python API (https://pypi.org/project/yfinance/) and finally visualizes them in a table-chart fashion.
It consists of a python script that downloads the investments' coordinates contained in data_entry.json from the server and updates (and uploads) the timeseries database every 24 hours.
Some HTML and CSS to construct the tables and a javascript snippet that pictures the graphs with the Google Chatrs API.
