Sly, the issues seem to be coming from the box size section. For other stocks depending on the SP, try a .50 or 1.00 box size instead of the SIRI box size of .01. That should bring up the chart. As for the trend lines the chart will automatically add the lines on most P&F charts. For some reason it does not with SIRI at .01 box size. If you change the SIRI box size to .25 or larger you will see the trend lines added. Try a .50 box size on SIRI so you can see both ascending and descending trend lines.
