Symbol data
Symbol data lists the raw figures the site holds for one symbol, exactly as received from the feed, for when you want to check a number rather than read a formatted page.
Most of the time the quote page is the right way to look at a share. Occasionally you need to verify a specific figure: whether a yield is calculated on the last dividend or the year's total, what the previous close actually was, or what bar the chart drew for a particular hour. This page shows you every field the feed supplies for the symbol, unformatted, together with the price bars for a frequency and range you choose, so you can see the exact number behind a formatted display.
It is a reference, not a trading screen. The same bid, offer, and last trade appear here as on the quote, but as plain fields with their names, and the bars are the same ones the chart draws.
