I just made a chage to the way the hover charts are launched. It is now easier to know where the charts are available and it should also be simpler to display them on Android devices. You'll now see a little chart icon next to stock ticker symbols in many of the tables around the site. Here's an example:
On a laptop or desktop computer you can simply hover your mouse pointer (cursor) over the chart icon and that stock's candlestick chart will appear. On mobile devices you can just tap the icon to reveal the chart. A second tap somewhere else on the screen will close the popped-up chart.
