The Pre-Market Indicator is calculated based on last sale of Nasdaq-100 securities during pre-market trading, 8:00 to 9:30 a.m. ET. And if a Nasdaq-100 security does not trade in the pre-market, the calculation uses last sale from the previous day's 4 p.m. closing price.
The After Hours Indicator is calculated based on last sale of Nasdaq-100 securities during after hours trading, 4:00 to 6:30 p.m. ET. And if a Nasdaq-100 security does not trade in the after hours market, the calculation uses last sale price from that day's 4 p.m. closing.
