Altogether, volume land inside 32 different half-hour buckets across the extended day.

Wetin be premarket and after-hours trading?

Premarket (4:00 a.m. to 9:30 a.m. ET) and after-hours (4:00 p.m. to 8:00 p.m. ET) na electronic-only trading windows around the normal trading day. Fewer participants dey trade for those periods, bid-ask spreads dey wider, and most brokers dey accept only limit orders for those sessions. Company news dey gather for these periods. Earnings releases dey come mostly just after the 4:00 p.m. close and during the hours before market open. Na those times stock price fit gap far from the previous close. Price wey print at 7:00 p.m. no guarantee where the stock go open the next morning.

The short version, as the panels above show: extended sessions dey real and person fit trade for them, but volume dey thin compared with the regular day.
