This looks awesome!

Where does the data come from? Is this a screenscraped source, or was the data purchased from a reliable data source? If it was screenscraped, are there possibly licensing issues with the NYSE, CME, etc?

Actually, every data page has "look-thru" to the source of the data. bottom of the page, under "Dataset Information", "Raw Data"
