So, as a side project, I wrote a scraper in nodejs to scrape for stock price information for all companies on the stock market. Now, I have a wealth of stock price information.<p>My original plan was to write a simple moving average analyzer that tells me when averages cross above or below each other.<p>What else could I do with this data? Any interesting analytics I could do? Just curious to see what other hackers might do with this information.
Well, the truth is that predictive behavior stuff has been done before. So, maybe you could go another way; you could use it to track influence.<p>Say a NY Times article comes out about the american banking industry. You could track the price ripple from that back to the source article release time and check out how quickly it snowballs. You could probably actually use that over a series to find who is most influential and in what sector. That might be interesting.
I'm not sure what you'd do with the data itself, but if you want to build some interactive charts to show off your project, Highcharts[1] is a good way to go.<p>1: <a href="http://www.highcharts.com/" rel="nofollow">http://www.highcharts.com/</a>
