what time frame does volume buzz cover. I didn't see it in the defination. Today it shows AAPL with a     -27% reading but the 30 day average volume is 104%. Most stocks are close but alot have big differences. I don't know why unless I know what time frame is Volume Buzz figured on?

thanks

Volume Buzz is based on the 100-Period Simple Moving Average of Volume over the previous 100 days (so not including today).

The current Volume is compared to a percentage of the average volume which is directly proportional to the percentage of the trading day which has already passed. So at 10:15 AM ET, the current volume would be compared to about 11.54% of the 100-Day Simple Moving Average of Volume ending yesterday. If the result is +25%, it would mean that current Volume is about 14.42% of the average volume instead of 11.54% of the average volume.
