>>934054>Ok. Then there ARE exchanges operating after hours.Yes, obviously.
>how do big exchanges get the ticker data from after hours?They buy it. Trade data is a commodity. All the exchanges sell it. Why do you think most sites only show 20-minute delayed trading data? (Hint: because real-time data costs money.)
>So I believe they are operating the pricing platform just not streaming it to the public. Am I right?No, each exchange has its own order book and trade data. An order placed on one exchange doesn't carry to another exchange, and therefore the bid and ask are unique to each. Sure its unlikely that they'd be too out of sync from minute to minute, but it could happen.
>I don't know what I'm talking about.No, you don't. But that's ok too.
