When you zoom to the deepest level in StockTouch, where you are looking at an individual stock, you should see that stock's price graph. If this is not visible, but the rest of the stock's information is displaying at the top of the screen (Price, 52-week range, etc.), then you may be suffering from connectivity issues.
If you are not on wifi, but using AT&T or Verizon 3G connectivity, you may be experiencing a data slowdown. Wait for a little while - 20-30 seconds - and see if the graph shows up. If it does not, please press the home button on your iPad and leave the app, then open it back up again. This may fix the problem. If this does not fix the problem, please email us (link at the right) so we can help you troubleshoot your problem. Thanks for your patience!
