I have a question regarding stocks. Mainly about the sell/update of value feature.

I have a lot of stocks and they only update once a day it since like, and I know Andrewkm told this himself.

Still this means selling your stock within 23 hours and 59min it will remain the same value?

OR (What I would prefer)

I understand they update once every 24 hour, to prevent lag.

Still you can check the value with other pages (Yahoo, google etc.) yourself. Still when you press the sell button, the server get the currently price updated when selling.

(Btw if its the first I might suggest the second with a suggestion. But I need to know how it work atm)
