不是 24 hour 的股票，怎么没到 pre-market 股价就涨了？

今天还有半个小时才盘前

Nasdaq:
Investors may trade in the Pre-Market (4:00-9:30 a.m. ET) and the After Hours Market (4:00-8:00 p.m. ET).

Robinhood:
Market hours: 9:30 AM–4 PM ET
Extended hours: 7–9:30 AM ET and 4–8 PM ET

原来是 Robinhood 的 premarket 比 Nasdaq 的要晚。天天号称自己最时髦，盘前开的这么晚？
