A simple code snippet to capture the current price for a symbol from MarketWatch.com
One of the ways to use it is in Google Sheets.
Google Sheets provides a convenienct function named FINANCE() to query stock
prices but if that doesn't work for you, you can go to the script editor and
paste the contents of MarketWatchQuotes.js/MarketWatchQuotes.js there.
Then, you can query the stock price of any symbol supported by MarketWatch using
the function call GETPRICE(). For example: GETPRICE("VTSAX").
