Getting Historical Stock Data in Asp.net

April 29, 2011 11:47 AM

I need to access historical stock data for an ASP.NET website

I'd like to do a ASP.NET website that does stock analysis based on historical data for individual US stocks. For example, if the user selected Amazon, it would do analysis based on Amazon stock prices for the past year. I'm trying to find a service where I could get this data...preferably free, if not very cheap. I don't need a real time feed, just historical data that I can get based on user requests. I've taken a look at google, but it looks like google finance is for personal use only. I haven't been able to find TOS for the yahoo API, although I know the RSS feeds page says "for non-commercial use only"...could someone point me in the right direction? Thanks.

Response by poster: Thanks, but I was more looking for the Dow Jones and NASDAQ. Also, that is a file download, I don't see any kind of API for programmatic access.

Here is some information about the Yahoo API and its limits or lack there of.

This is not free, but does not seem to expensive - pricing (via)

The pricing of this is unclear too - but it may help
