Very interesting discovery. Thanks for your post. Regarding www.freestockcharts.com I had been using it for a couple of months when I discovered that the realtime data is slow in coming in or not accurate at all at times compared with my on-line broker's data. The data can be 15 or 20 seconds slow in arriving and sometimes just doesn't seem to come in for much longer periods. I would be very cautious using this for realtime trading.

I have switched to www.advfn.com and find it very accurate and much better. It costs $9.99/month for US markets realtime streaming charts, and you can open as many charts as you want in separate windows so you can view them at the same time. I would recommend using Firefox as your browser for this, as it uses much less in computer resources.
