数字货币是一个初级的市场,暂时是没有监管的。而对于股市来讲,这个市场可以被称为一种职业。而职业自然就需要有假日。最关键的还是股市在周末流动性很低,所以被称为after hour trading risk。股市不是用来炒作的,所以不必每天24小时交易。如果有重大消息,4x5的交易时间足够消化了。! k) R% b# o& F; {( u1 {# e

Brokers managing accounts, Portfolio Managers, and Managers of Mutual Funds doing stock picks etc. Those folks are still initiating a very large number of the trades (or at least one side of a trade). And those humans don't work 7 days a week.

The portfolios were designed to track indexes, or a mix of indexes and actively managed funds, but with the addition of managing for tax efficiency. A lot of complex math and complicated 'solver' programs that figured out each day what if anything to trade in each portfolio. Despite all those computers, humans still reviewed all the trades to be sure they made sense. And those humans only worked 5 days a week.8 _* |5 R$ y: J

Because a smaller amount of stock is being traded, prices are more influenced by single sales, and they're more volatile. It also makes it harder to match sellers’ asking price to buyers’ bids, making it difficult to complete transactions. Prices quoted during after-hours sessions aren’t “official” and don’t reflect the price for the stock upon opening. Because the system favors limit orders -- orders in which you set your maximum bid, and let the computers match you to a seller -- it can be difficult to find the best price during after-hours trades.
