As a newbie can someone explain in layman’s terms what trading takes place after the market has closed.
The reason I ask is I’ve noticed when the market closes I may have for example £10 in credit, then I may look later and it could have risen or fallen, so what caused that?
I mean if I decide to buy or sell a stock after the close the transaction doesn’t take place till the market opens, if I have it right.
