Snapshot 0.7

Snapshot 0.7

The major changes in version 0.7 is to resolve a few critical bugs in "open/close position" module, AJAX-implemented "business news" module and the new "currency chart".

This candlestick chart will draw the historical data over years, the draw back is slow in response. An average historical external feed will take out 1KB to 10KB+ bandwidth, although the JFreeChart perform drawing in a fair time, it still consider to be slow. 10KB x 1000 simultaneous requests will easily consumed around 10MB bandwidth of the server at one time (not including delay for each data fetch), a very powerful server is require to handle that kind of traffics.
