Then it's multiple sellers and multiple buyers but same logic applies, just multiply it. It's like me selling to carbon, me selling to you at the same time, while you and rama, bluegoose and lollot etc etc Usually the trade happens or at least the agreement between parties happens during the day, then the brokers execute or more precisely they get registered by the platform afterhours.Those times are just when they get processed not necessarily when the trade actually happened. You can get a more straightforward answer from your broker, just give them a call. You don't see them a lot on ASX but they do happen. They happen a lot on Nasdaq. I do it sometimes when I transfer shares between companies.
