There are a number of setting that you can use to control how mStocks+ works. These settings are in the preferences screen.
Most of these are pretty straightforward. You should experiment with these to determine how they change mStock+.
The refresh settings are useful to change how frequently mStocks+ updates the price data for each symbol that you have added. Since this can be resource intensive, there is no sense doing it when the markets are closed. You can tell mStocks when you would like to do the updates on this screen.
Ticker Tape Settings
The Ticker Tape has a number of settings that allow you to control its appearance. Make changes to the settings while the Ticker Tape is running and it will be updated with the new option.
News and Chart Settings
