For the record, I responded to your message about one hour after it was posted here (i.e., on October 18). I actually saw your snapshot chart less than 20 minutes after you posted it.

I should also point out that using automated scripts to pull charts from our website is prohibited by our Terms of Use agreement. Specifically:
