I have seen that certain people said that market will never sleep. As I know, like usual market at NASDAQ or NYE Stock Market they usually open their market at 9.30 a.m. to 4 p.m. So why does it call market never sleep? I am curious. I am new to this kind of thing
how will the market sleep if its users are active for 24 hours, from different worlds exist, with different time zones from different countries.
