I would imagine that most data vendors do offer the ability to link real-time data to an Excel spreadsheet. I have created spreadsheets that are linked to my trading platform using real-time quotes and then I can sort by various choices. I copied a list of ETFs (over 200) from finance.Yahoo.com and I can see which ones are moving on a percentage basis in real-time. Yahoo is delayed data. I can do the same thing for futures to look for high volume situations real-time in Excel.
