Free stock charts is a charting application with a long history and one I used myself back in the very early days. It has come a long way since then and is now part of the TC 2000 platform. I reference it here for you as the charting is excellent, and even more important, so is the volume. In addition, they have recently added a suite of options tools, making it more powerful still, so it may be an application you might wish to run alongside your others and use for analysis.
