The hard drive based application. I use the web update feature that pulled Yahoo's historical data to generate the charts. The problems arise when a stock split occurs because Yahoo does not adjust their old data and only reports the stock split as a field in the historical data. As an example SBUX is reported as such:

25-Oct-05 	28.00 	28.10 	27.55 	27.89 	5,648,500 	27.89 
 24-Oct-05 	27.67 	28.25 	27.50 	27.89 	6,303,900 	27.89 
 24-Oct-05 	2 : 1 Stock Split 
 21-Oct-05 	54.97 	55.25 	54.40 	55.01 	7,609,200 	27.50 
 20-Oct-05 	54.58 	55.09 	53.79 	54.19 	8,358,000 	27.09
