How do Finance Site generate Stock Charts?
Are there massive Databases storing this information?
Curious...

RE: Stock Chart Generation
I am sure they have to have giant databases full of that info...i know that Yahoo Finance is run with php....

Actually, I just looked at the very bottom of the finance.yahoo.com page and saw this:
Quote:
Quote technology by TIBCO Software, Inc. Historical chart data and daily updates provided by Commodity Systems, Inc. (CSI). Quote data provided by Reuters. Market Cap and Avg Vol provided by Market Guide.

So, it looks like they are grabbing that data from a couple of services. Makes sense, TIBCO and Commodity Systems probably make a living on supplying data like that....

RE: Stock Chart Generation
I figured as much...
I'm already using a product that webfetches data. I was working on something that's less out sourcing and more in house.
Yet... I've come to a stand still with the Charting portion of the App.
