jStocks - jQuery Stocks
A small page based using jQWidgets to get some stocks information, through Yahoo Finance API. Allows to apply indicators, choose symbols and period of time.
OBS: Works only for Bovespa (Brazilian stock market), but with a few modifications it is possible to work with any stock available on yahoo finance.
Feel free to download, modify and copy (or throw in the trash :-) ) the source code.
