BlockBeats 消息，12 月 16 日，据外媒报道，纳斯达克正计划于周一向美国证券交易委员会提交文件，以推出全天候的股票交易服务。纳斯达克计划将股票和交易所交易产品（ETP）的交易时间从目前的每周五天、每天 16 小时延长至 23 小时。纳斯达克的“5X23”新模式将分为两个主要交易时段：
日间时段 从美东时间凌晨 4 点开始，到晚上 8 点结束。此时段将继续包含盘前、常规和盘后交易时段，常规交易时段的开盘钟（9:30）和收盘钟（4:00）将保留。夜盘时段从美东时间晚上 9 点开始，到次日凌晨 4 点结束。此时段，晚上 9 点至午夜 12 点之间执行的交易，将被视为属于下一个日历日的交易。根据新计划，交易周将从周日晚上 9 点开始，在日间时段结束后于周五晚上 8 点结束。(金十)
