That link still works. That would be all I need if I could get it to display the last 20 trading dates. Anyone know how to do that?
I also use the ichart.finance.yahoo.com/table but I only use it to get a list of dates where the market is open. Does anyone know of a simple and easy link that I can use to download a text file containing a list of dates where the markets are trading? (Excluding holidays and such)
