There are a number of significant errors that can lead to incorrect feedback to the user:

The highest price shown on HSBC is 10 cents lower than it actually was............

1. see enclosed example of HSBC 04-AUG-2010

pics
1. what the program shows
2. program does not even agree with itself
3. actual data taken from a service
4. far more detail

This sort of bug should not present, it is far to easy to check and remove such errors, by cross referencing against a number of different services.

    JStock is not designed for high frequency trading. Hence, the intra-day chart which is being show is just "approximate". This is because JStock is getting data from Yahoo free data source. The "accuracy" of the intra-day data, is determined by many factors. Network speed, JStock scanning speed, Yahoo server respond speed, Computer CPU speed... All these factors being added up, make JStock is not suitable to be used for high frequency trading.
