Live data representation of stock

in General Discussion • Other • 1 year ago

Hello,

Sorry but I am a little new to processing. I am wondering if it is possible to represent a live feed of stock through processing.

What I want to do is have D.R. Horton Inc stock http://finance.yahoo.com/q?s=DHI control and then have that control the opacity or brightness of a jpg.

Does anyone have any idea how this might be possible? Thanks!

Here's a start...

String url = "http://finance.yahoo.com/q?s=DHI";
String[] site = loadStrings(url);
println(site);
exit();

The next step is to find what you want in there, for example the value of something. Then write some code to just extract that value from the whole page. Once you have a value, use the map() function to convert it to a 0-255 range, which you can use to control the opacity or brightness of the image. Once you got this up and running, you can re-check the value every so much frames or milliseconds.
