What happens at 8 am ET that makes the 8:00 - 9:30 time period normal versus 4:00 - 8:00?
Does something technically differ between the two time periods or is it just the fact that volume is higher during the last 1.5 hours?
I can see that Interactive Brokers allows trading from 4 am whereas e.g. Charles Schwab only allows trading from 8 am.
