Hi Alexis !

[fastflyer]

I did the neophyte task of searching and found this gem - Almost exactly what I wanted. My programming level is - I know enough to be dangerous, but I'm getting slightly less so over time, much too slightly.

Anyway, I was wondering if you could add another feature to this elegant code you wrote a few years ago to include - the opening value at a particular time. In my case, I'll be setting it to 9:30.

Thank You Once Again,

Glenn Swiatek
