Author	Topic: daily volume covers what times? (2 messages, Page 1 of 1)
orbwen -Interested User- Posts: 12 Joined: Feb 5, 2011	Posted: Jul 10, 2011 06:45 PM Msg. 1 of 2 Can anyone please clarify for me... I thought the daily volume reported from daily historic requests included only trades during market hours 9:30am-4pm EST. But it looks like this is not the case. On 6/24, most stocks of the scores I checked did half or more of their trades after-hours according to the intraday statistics. So when final volume is reported for a “day” what time period is this supposed to cover? 9:30am to 9:30am the next day? Midnight to midnight? Is there a special cutoff time each evening a few hours after market close? I understand the numbers will not always agree exactly -- the exchanges report their official numbers based on adjustments we don't have visibility into. Many thanks! Jonathan
