Rewritten in GoLang (versus JavaScript)
Displays stock quotes in a table format with color-coding of wins/loss and sparklines for the last 20d
Install by moving the folder stock.widget to the Übersicht widget folder.
Adjust bottom and right in the style section in index.coffee if you want it placed somewhere else on the screen
Adjust and amend stock list in src/config.json
Since it seems that the Yahoo Finance API has been deprecated as had been the Google Finance API, I switched to the Robinhood Private API, documented here, which for now allows querying real time stock quotes and get good historicals to plot the sparklines.
This however doesn't allow for Stock Indexes, Currency or non US markets, AFAIK.
