	looks like this question spans across 2 threads.....no matter, I'll repeat it here too........ we use the 5pm NY close as it's the "recognized" cut-off trigger, certainly amongst the provider desks we deal thru anyway.....it's also the (interest) rollover time period...... we calc the weekly pivots (for the following weeks activiry) based on Fridays close......same for monthly numbers - the close of the specific weekly/monthly bar on the final trading day of the week/month..........

Thanks Buk.
I see that not all use the same times for calculation. Though 5pm seems to be common in stuff I read or people I talk to.
